New Cancer Treatment Breakthroughs (2026 Update): The Biggest Advances Changing Cancer Care

Despite trillions spent on cancer research (1), cancer still kills around 10 million people a year (2) and is a leading cause of death globally, according to the World Health Organization. Cancer research continues to advance at an unprecedented pace, with new treatments offering hope to millions of patients worldwide.

The 2026 American Association of Cancer Research (AACR) Annual Meeting took place in San Diego from April 17-22 and reflected how cancer research continues to evolve. Progress is increasingly driven by how advances across biology, technology, and policy come together to shape how we understand disease, develop new treatments, and bring them into practice.

A central theme this year was the continued focus on cancer as more than just a collection of tumor cells. It is shaped by a complex ecosystem — immune cells, surrounding tissue, metabolism, and even the microbiome — all interacting in dynamic ways.

As we enter 2026, several groundbreaking therapies and innovations—including next-generation immunotherapy, gene-editing technologies, repurposed drugs, and alternative cancer treatments—are reshaping cancer care.

Here are some of the most promising breakthroughs to watch for this year:

1. Next-Generation Immunotherapies

Perhaps the most transformative breakthrough in modern oncology has been the rise of immunotherapy—a set of treatments that awaken the immune system to recognize and attack cancer cells. It is an idea as beautiful as it is powerful: train the body to see the enemy hiding in plain sight.

Advances in immunotherapy continue to improve survival rates. Novel checkpoint inhibitors, CAR-T cell therapies, and bispecific antibodies are expanding treatment options for hard-to-treat cancers like pancreatic and brain tumors.

Intra-tumoral immunotherapy represents a promising strategy to convert tumors into in situ vaccines, offering targeted immune activation with reduced toxicity. While clinical success has been observed in accessible tumors like melanoma, challenges persist in achieving consistent systemic responses and treating visceral metastases. Future advancements in delivery techniques and combination therapies hold significant potential to broaden its applicability.

Checkpoint Inhibitors

Checkpoint inhibitors were the first major triumph in this domain. Cancers like melanoma, lung cancer, and Hodgkin’s lymphoma once carried grim prognoses. Now, drugs such as nivolumab (Opdivo), pembrolizumab (Keytruda), and atezolizumab have offered durable responses—sometimes even complete remission—by blocking the “brakes” cancer places on immune cells.

CAR-T-cell therapy

But checkpoint inhibition is just the beginning. CAR-T cell therapy has taken the world by storm, especially in blood cancers. This process involves harvesting a patient’s T-cells, genetically engineering them to recognize a cancer-specific antigen, and infusing them back into the bloodstream. These modified cells become hunters. In diseases like B-cell leukemia, CAR-T therapy has shown cure rates of over 80% in patients who had exhausted every other option.

A key theme at AACR 2026 was a deeper focus on why immune responses fail. Even when immune cells are present, tumors can create conditions that push those cells into a dysfunctional state, reframing resistance as a dynamic state that may be reversible. 

Cell therapies such as chimeric antigen receptors (CAR) T-cell therapy continue to demonstrate the potential of immune-based approaches. The AACR-ASCO Joint Session showcased ongoing efforts to expand CAR T- and other engineered cell therapies into solid tumors, where efficacy has remained one of the field’s most persistent challenges. These next-generation approaches aim to improve durability, targeting, and safety.

A treatment that makes immune cells hunt down and kill cancer cells was declared a success for leukaemia patients in 2022. In the journal Nature, scientists at the University of Pennsylvania announced that two of the first people treated with CAR-T-cell therapy were still in remission 12 years on.

More recently, the same journal announced that a woman treated with CAR-T therapy as a four-year-old is in remission 19 years later.

However, the US Food and Drug Administration is currently investigating whether the process can in fact cause cancer, after more than 30 cases of secondary cancer were observed in patients receiving CAR-T therapies. The jury is still out as to whether the therapy is to blame but, as a precaution, the drug packaging now carries a warning.

New research is pushing CAR-T therapy into solid tumors—a far more complex challenge due to the tumor microenvironment and antigen heterogeneity. Trials in glioblastoma, pancreatic cancer, and ovarian cancer are underway, with engineered cells being further augmented with “logic gates” and “safety switches” to navigate the maze of normal tissues.

Immunotherapy vs Chemotherapy

Chemotherapy still saves lives and remains essential in many cancers. But for a growing number of patients, we now have better options. These are treatments that are more targeted, more personalized, and often less toxic.

According to Dr Daniel Flora, an oncologist:

I specialize in melanoma and early-phase clinical research, and I haven’t prescribed chemotherapy for melanoma in years. Instead, I offer immunotherapy, targeted therapy, and clinical trials with promising approaches like bispecific T-cell engagers (BiTEs) and tumor-infiltrating lymphocytes (TILs). These therapies are designed to work with the immune system or go after specific cancer targets. We’ve made real progress, though there is still more work to do.

This shift is happening across oncology. Here are ten cancers where chemotherapy is used less often, replaced by more effective or better-tolerated treatments:

1. Melanoma Immunotherapy and targeted treatments are now the primary tools. Chemotherapy is rarely used.

2. Chronic Myeloid Leukemia (CML) Oral tyrosine kinase inhibitors like imatinib allow most patients to live normal lifespans without chemotherapy.

3. Chronic Lymphocytic Leukemia (CLL) Targeted drugs like venetoclax and BTK inhibitors are commonly used first-line. Chemotherapy is now the exception.

4. MSI-High Colorectal and Endometrial Cancers Immunotherapy can provide long-lasting responses for patients with mismatch repair deficiency.

5. ER+ Breast Cancer (Low Oncotype DX Score) Hormonal therapy alone is often appropriate when genomic testing shows a low recurrence risk.

6. PD-L1 High Non-Small Cell Lung Cancer Single-agent immunotherapy may be more effective and better tolerated than chemotherapy in selected patients.

7. Advanced Prostate Cancer Hormone-targeting agents like enzalutamide and abiraterone are now preferred over chemotherapy in many cases.

8. Kidney Cancer Most patients now receive immunotherapy and VEGF inhibitors, not chemotherapy.

9. Liver Cancer (HCC) The combination of atezolizumab and bevacizumab has become a standard first-line treatment.

10. Multiple Myeloma Treatment now often starts with monoclonal antibodies and other targeted agents, reducing the need for traditional chemotherapy.

We still rely on chemotherapy when the evidence supports it, particularly when it improves cure rates. But in many cases, we are moving toward more refined treatment strategies.

People are often surprised when I tell them I rarely prescribe traditional chemotherapy anymore.. As an oncologist, it’s meaningful to be able to offer patients better options. And when a clinical trial is available that could replace chemotherapy with something more precise or less toxic, I do my best to make that available. (Dr Daniel Flora)

2. Breakthrough Targeted Cancer Therapies

Recent oncology innovations show that targeted therapy remains a cornerstone of modern cancer treatment — particularly when paired with metabolic and immune strategies. According to a 2026 review of emerging advancements in cancer care, targeted therapies are part of a multi-modal landscape that includes precision gene editing and molecular profiling. Therapies targeting tumors with KRAS mutations — once considered “undruggable” — are beginning to show promising results in pancreatic and lung cancers, with data from Revolution Medicines pointing to new possibilities in some of the field’s most challenging diseases.

Key developments include:

  • Precision Targeted Drugs — New compounds designed to inhibit specific oncogenic pathways (e.g., KRAS, EGFR, BRAF) are now entering clinical trials or receiving regulatory attention, enhancing the ability to tailor treatment to individual tumour profiles.

  • Molecular Profiling for Therapy Selection — Advanced sequencing and biomarkers such as ctDNA (liquid biopsies) allow clinicians to match patients with targeted agents more effectively and adjust therapy in real time.

  • Combination Targeted Approaches — Strategies that simultaneously block multiple signalling pathways are being evaluated to delay resistance mechanisms that often limit the effectiveness of single-agent therapies.

For patients with actionable mutations identified through molecular profiling, targeted therapies are the preferred treatment approach. These include:

  1. PARP inhibitors for BRCA mutations,

  2. NTRK inhibitors,

  3. immune checkpoint inhibitors (e.g. pembrolizumab, dostarlimab) for MSI-H/dMMR,

  4. KRAS G12C inhibitors,

  5. anti-HER2 agents, and

  6. BRAF/MEK inhibitors.

  7. Melanoma: Immunotherapy and targeted treatments are now the primary tools. Chemotherapy is rarely used.

  8. Chronic Myeloid Leukemia (CML): Oral tyrosine kinase inhibitors like imatinib allow most patients to live normal lifespans without chemotherapy.

  9. Chronic Lymphocytic Leukemia (CLL): Targeted drugs like venetoclax and BTK inhibitors are commonly used first-line. Chemotherapy is now the exception.

  10. MSI-High Colorectal and Endometrial Cancers: Immunotherapy can provide long-lasting responses for patients with mismatch repair deficiency.

  11. ER+ Breast Cancer (Low Oncotype DX Score): Hormonal therapy alone is often appropriate when genomic testing shows a low recurrence risk.

  12. PD-L1 High Non-Small Cell Lung Cancer: Single-agent immunotherapy may be more effective and better tolerated than chemotherapy in selected patients.

  13. Advanced Prostate Cancer: Hormone-targeting agents like enzalutamide and abiraterone are now preferred over chemotherapy in many cases.

  14. Kidney Cance: Most patients now receive immunotherapy and VEGF inhibitors, not chemotherapy.

  15. Liver Cancer (HCC): The combination of atezolizumab and bevacizumab has become a standard first-line treatment.

  16. Multiple Myeloma: Treatment now often starts with monoclonal antibodies and other targeted agents, reducing the need for traditional chemotherapy.

These developments underscore that targeted therapy continues to evolve, especially when integrated with diagnostics, immunotherapy, and systems-level treatments. However, their impact on long-term survival still depends on addressing host metabolic and immune context — a theme central to OneDayMD’s metabolic–immune framework.

3. AI-Driven Drug Discovery and Clinical Research

Artificial intelligence is revolutionizing drug discovery by identifying new cancer-fighting compounds at an accelerated rate. AI algorithms analyze vast datasets to pinpoint potential treatments, significantly reducing the time required for drug development.

Artificial intelligence is now being used across the research pipeline, from drug discovery to trial design, helping analyze data and identify patterns more quickly and consistently. At the same time, new platforms from companies such as 10x Genomics are enabling researchers to analyze tumors at single-cell resolution and within their spatial context, offering a more detailed view of how cancer and immune cells interact.

Randomized controlled trials (RCTs) are costly and time-consuming endeavors. Incorporating computational simulations and AI algorithms into RCT design could enhance trial efficiency, optimize protocols, and ultimately inspire more real-world research. This innovative approach holds promise to reduce costs, speed up the development process, and improve the relevance and accuracy of clinical findings.

AI-based Risk Profiling

In India, World Economic Forum partners are using emerging technologies like artificial intelligence (AI) and machine learning to transform cancer care. For example, AI-based risk profiling can help screen for common cancers like breast cancer, leading to early diagnosis. AI technology can also be used to analyze X-rays to identify cancers in places where imaging experts might not be available. These are two of 18 cancer interventions that the Centre for the Fourth Industrial Revolution India, a collaboration with the Forum, hopes to accelerate.

AI-Assisted Radiotherapy

Radiotherapy is becoming more precise with AI-powered systems that tailor radiation doses to individual patients. This reduces damage to healthy tissues and improves overall treatment outcomes.


4. Intra-Tumoral Chemotherapy Is Reviving Localized Precision Cancer Treatment

Another emerging breakthrough is intra-tumoral chemotherapy — a strategy that delivers anti-cancer drugs directly into the tumor itself rather than throughout the entire body.

Instead of flooding the bloodstream with chemotherapy, doctors inject the treatment precisely where it is needed.

This approach aims to:

  • increase drug concentration inside tumors,

  • reduce systemic toxicity,

  • minimize side effects,

  • and potentially stimulate anti-tumor immune responses.

Intra-tumoral therapy is gaining renewed interest because many cancers develop:

  • poor blood supply,

  • hypoxic regions,

  • dense stromal barriers,

  • and drug-resistance mechanisms that limit intravenous chemotherapy effectiveness.

By bypassing some of these barriers, localized delivery may improve treatment penetration.

Why Intra-Tumoral Therapy Matters

Traditional chemotherapy often struggles with the classic oncology dilemma:

enough drug to kill the tumor may also damage healthy tissue.

Intra-tumoral approaches attempt to improve the therapeutic ratio:

  • higher local tumor exposure,

  • lower systemic exposure.

This is particularly attractive for:

  • pancreatic cancer,

  • liver tumors,

  • melanoma,

  • head and neck cancers,

  • glioblastoma,

  • and accessible solid tumors.

Researchers are also exploring combinations with:

  • immunotherapy,

  • radiotherapy,

  • nanoparticles,

  • oncolytic viruses,

  • and thermal ablation.

New Technologies Driving the Revival

Several innovations are helping intra-tumoral chemotherapy re-emerge as a promising field:

Drug-Eluting Systems

Slow-release implants, gels, and microspheres can continuously release chemotherapy inside tumors over days or weeks.

Nanoparticle Delivery

Nanotechnology may improve:

  • tumor penetration,

  • drug stability,

  • and selective targeting.

Image-Guided Injection

Modern imaging allows more precise placement using:

  • ultrasound,

  • CT guidance,

  • MRI guidance,

  • or endoscopic ultrasound.

Combination Immunotherapy

Localized tumor destruction may release tumor antigens and potentially enhance immune activation when paired with checkpoint inhibitors.

Some researchers describe this as turning the tumor into an “in situ vaccine.”

Intra-Tumoral Therapy and the Future of Multi-Modal Oncology

Intra-tumoral chemotherapy reflects a larger shift in oncology:

from broadly systemic treatment toward highly localized and precision-guided interventions.

Future cancer care may increasingly combine:

  • systemic immunotherapy,

  • targeted therapy,

  • radioligand therapy,

  • metabolic approaches,

  • and localized intra-tumoral treatments.

Rather than replacing standard therapies, intra-tumoral chemotherapy may become another important chess piece in personalized cancer treatment strategies.

Important Reality Check

Despite growing excitement, intra-tumoral chemotherapy remains:

  • experimental in many cancers,

  • technically challenging,

  • and not universally applicable.

Some tumors are difficult to access safely, while others may already have widespread microscopic metastases requiring systemic therapy.

Large randomized trials are still needed to determine:

  • survival benefit,

  • optimal drug combinations,

  • patient selection,

  • and long-term outcomes.

However, the field is gaining momentum as oncology increasingly focuses on:

  • precision delivery,

  • reduced toxicity,

  • and smarter combination therapies.


5. Repurposed Drugs and Metabolic Therapy: Unlocking New Potential in Integrative Cancer Treatment

Why 'repurposed drugs' and 'metabolic therapy' are trending on social media platforms — and what it actually means.

A significant breakthrough in 2025 and 2026 is the growing and trending use of repurposed drugs as complementary cancer treatments—medications originally developed for non-cancer conditions but now showing promise in oncology. 

Cancer treatment “breakthroughs” are not just new drugs—they are advances that meaningfully change survival, remission rates, or quality of life, often by introducing a new mechanism of action, a new way to select patients, or a less toxic approach.

Access to effective, cancer-specific therapies remains limited, particularly in impoverished and low- and middle-income countries where cancer survival rates lag behind those in high-income settings due to inadequate funding and infrastructure (source, source). 

Repurposing drugs is a well-established and highly effective approach within the pharmaceutical industry. Rather than developing entirely new compounds from scratch—a process that can be costly, time-consuming, and fraught with uncertainty—companies identify new therapeutic uses for existing drugs. This strategy not only accelerates the development timeline but also leverages existing safety and efficacy data, reducing regulatory risks.

Many blockbuster drugs owe their commercial and clinical success to this approach. For example, Viagra was initially developed to treat hypertension and angina but found enormous success as a treatment for erectile dysfunction. Keytruda, originally designed for melanoma, has since been approved for a wide range of cancers, including lung, bladder, and head and neck cancers, significantly expanding its market potential. Similarly, Ozempic was first developed for type 2 diabetes management but has gained attention for its effectiveness in weight management, tapping into a new patient population.

Drugs like ivermectin, mebendazole, and fenbendazole, traditionally used as antiparasitic agents, are being studied for their anticancer properties. A peer-reviewed protocol published in September 2024, led by researchers such as Dr. Ilyes Baghli and Dr. Paul Marik, demonstrates that these drugs can disrupt cancer cell growth by targeting microtubules, essential for cell division [Baghli et al 2024].

Additionally, drugs like metformin, originally developed for diabetes, and anastrozole, a breast cancer treatment now repurposed for prevention, are gaining traction. Metformin disrupts cancer cell metabolism, while anastrozole reduces estrogen levels to lower breast cancer risk. These repurposed drugs are particularly valuable in low- and middle-income countries, where access to expensive therapies is limited, and their established safety profiles accelerate their integration into clinical practice.

While anecdotal reports, such as more than 700 case studies on fenbendazole (N=700), suggest benefits, controlled clinical trials are needed to confirm efficacy. Patients considering these treatments should consult integrative oncologists to tailor protocols to their needs.

6. Personalized Cancer Vaccines and Gene Therapy

Cancer vaccines have evolved beyond prevention, with new personalized vaccines targeting individual tumors. These mRNA-based therapies train the immune system to recognize and attack cancer cells, offering a promising avenue for highly tailored treatments. 

Thousands of NHS cancer patients in England could soon access trials of a new vaccine treatment. It's designed to prime the immune system to target cancer cells and reduce recurrence risk. These vaccines are also hoped to produce fewer side effects than conventional chemotherapy. Thirty hospitals have joined the Cancer Vaccine Launch Pad, which matches patients with upcoming trials using the same mRNA technology found in current COVID-19 jabs. Over 200 patients from the UK, Germany, Belgium, Spain and Sweden will receive up to 15 doses of the personalized vaccine, with the study expected to complete by 2027.

Repurposed drugs like metformin are being explored as part of alternative cancer treatment strategies to enhance immune responses by altering cancer cell metabolism, potentially boosting vaccine efficacy in combination therapies [PubMed 2021].

Cancer Gene Therapy

Gendicine (recombinant human p53 adenovirus), developed by Shenzhen SiBiono GeneTech Co. Ltd., was approved in 2003 by the China Food and Drug Administration (CFDA) as a first-in-class gene therapy product to treat head and neck cancer, and entered the commercial market in 2004.


The global cancer gene therapy market size was valued at USD 1.68 billion in 2021 and is expected to expand at a compound annual growth rate (CAGR) of 20% from 2022 to 2030. The growth of the market is attributed to factors such as the growing demand for gene therapy and an increased incidence of cancer cases across the globe. 

Gendicine is a biological therapy that is delivered via minimally invasive intratumoral injection, as well as by intracavity or intravascular infusion. The wild-type (wt) p53 protein expressed by Gendicine-transduced cells is a tumor suppressor that is activated by cellular stress, and mediates cell-cycle arrest and DNA repair, or induces apoptosis, senescence, and/or autophagy, depending upon cellular stress conditions.

In the 20 years since its introduction, tremendous progress has been made in identifying and developing clinical therapeutic trials for Gendicine in patients with a variety of cancers, including lung cancer, head and neck cancer, liver cancer, and cervical cancer. There are several advantages associated with rAd-p53 administration, including a high efficiency of gene transfer, with nearly 100% transduction efficiency, and it can transduce different types of cells in different human tissues. It also has high safety and controllability, as well as easy storage and transportation. It was estimated that nearly 30,000 people had been treated with Gendicine by 2013. The treatment resulted in a 30%–40% complete response rate and a 50%–60% partial response rate, for a cumulative response rate of over 90%. Notably, Gendicine also has few adverse effects and mild cytotoxicity to non-cancer cells.

Thirteen published studies that include long-term survival data showed that Gendicine combination regimens yield progression-free survival times that are significantly longer than standard therapies alone. Although the p53 gene is mutated in >50% of all human cancers, p53 mutation status did not significantly influence efficacy outcomes and long-term survival rate for Ad-p53-treated patients.

CRISPR Gene Editing in Cancer Therapy

CRISPR technology has progressed to clinical trials, allowing scientists to edit genes within cancer cells or immune cells to enhance treatment. This approach aims to correct genetic mutations responsible for tumor growth and improve immune system targeting.


7. Precision Medicine and Genomics

Precision medicine, powered by advances in genomics, is revolutionizing how cancer is diagnosed, treated, and even prevented. Unlike the traditional “one-size-fits-all” approach, precision medicine tailors prevention and treatment strategies to each person’s unique genetic makeup, environment, and lifestyle. 

Precision oncology is the “best new weapon to defeat cancer”, the chief executive of Genetron Health, Sizhen Wang, says in a blog for the World Economic Forum. This involves studying the genetic makeup and molecular characteristics of cancer tumours in individual patients. The precision oncology approach identifies changes in cells that might be causing the cancer to grow and spread. Personalized treatments can then be developed.

The 100,000 Genomes Project, a National Health Service initiative, studied more than 13,000 tumour samples from UK cancer patients, successfully integrating genomic data to more accurately pin-point effective treatment. Because precision oncology treatments are targeted – as opposed to general treatments like chemotherapy – it can mean less harm to healthy cells and fewer side effects as a result.

This shift is leading to more effective therapies, fewer side effects, and earlier interventions (PubMed, Cancer Australia). 

Molecular Profiling and Liquid Biopsies for Early Detection

Work presented at AACR 2026 by CRI Research Scientist Fahad Benthani, PhD, further revealed how the clinical landscape is evolving. Analyses of more than 24,000 global immunotherapy trials show increasing diversity in therapeutic approaches and combination strategies, along with shifts in how biomarkers guide development.

Liquid biopsies—blood tests that detect cancer-related genetic mutations—are becoming more refined and accessible. These non-invasive tests allow for early cancer detection, real-time monitoring, and personalized treatment adjustments.


8. Pancreatic cancer breakthrough 2026

Pancreatic cancer is one of the deadliest cancers. It is rarely diagnosed before it starts to spread and has a survival rate of less than 5% over five years. At the University of California San Diego School of Medicine, scientists developed a test that identified 95% of early pancreatic cancers in a study. The research, published in Nature Communications Medicine, explains how biomarkers in extracellular vesicles – particles that regulate communication between cells – were used to detect pancreatic, ovarian and bladder cancer at stages I and II. And now a new test, coined PAC-MANN, can pick up signs of the disease from just one drop of blood, say researchers.

Scientists are also getting closer to a cure. A US/UK study has discovered that pancreatic cancer shuts down particular molecules in a key gene. The hope now is that the new knowledge "could lead to the development of more effective treatment options in the future”, Dr Chris Macdonald, head of research at Pancreatic Cancer UK, told The Guardian.

The Future of Cancer Treatment: Combination Strategies

Cancer is rarely defeated with a single intervention. Think of cancer therapy as a chessboard:

you do not win with one powerful move alone.

You win by coordinating multiple pieces to achieve strategic advantage.

Increasingly, future oncology may involve combinations such as:

  • immunotherapy,
  • targeted therapy,
  • radioligand therapy,
  • surgery,
  • metabolic therapy,
  • anti-angiogenic approaches,
  • repurposed drugs,
  • lifestyle interventions,
  • and precision diagnostics.

The future likely belongs to personalized, adaptive, multi-modal cancer care.

Important Reality Check

Despite extraordinary progress, cancer remains incredibly complex. Many “breakthroughs” generate headlines long before proving meaningful survival benefit in large human trials.

Some therapies work spectacularly for small subsets of patients but not for most people. Others improve progression-free survival without significantly extending overall survival. Careful interpretation of evidence matters.


Bottom Line

The landscape of cancer treatment in 2026 is marked by rapid innovation, from high-tech solutions like CRISPR and AI to practical, cost-effective alternative cancer treatments like repurposed drugs and holistic integrative approaches.

The overarching message from AACR 2026 is clear: cancer research is moving from a focus on individual discoveries to a focus on integration, connecting biology, technology, and policy to deliver real-world impact. This progress reflects the work of a broad community of researchers, including members of the CRI network who contributed findings across basic immunology, translational science, and clinical research at this year’s meeting.

The most important cancer breakthroughs of 2025–2026 include:

  • expansion of immunotherapy,
  • next-generation CAR-T and CAR-NK therapies,
  • antibody-drug conjugates,
  • radioligand therapy,
  • AI-driven oncology,
  • precision medicine,
  • and earlier cancer detection.
The science continues to advance rapidly. The opportunity now is to ensure that progress reaches patients — faster, more equitably, and with greater precision.

These advancements bring new hope for patients and medical professionals, particularly in making advanced care more accessible globally. While many of these breakthroughs are still in early stages, their potential to revolutionize cancer care is undeniable. 

Rather than a single “cure for cancer,” the field is moving toward increasingly personalized treatment strategies tailored to the biology of each patient and tumor.

The oncology revolution is real — but it is happening through many coordinated advances rather than one magic bullet.

Staying informed about the latest advancements, including the promise of repurposed drugs, can help patients and caregivers make more informed treatment decisions.
