Breast cancer that has begun to spread could be controlled for longer with targeted radiotherapy

European Society for Radiotherapy and Oncology (ESTRO)
Reports and Proceedings

Treating breast cancer that has begun to spread around the body with targeted radiotherapy could help patients to live longer without their cancer getting worse, according to the results of a small randomised controlled trial presented at the Congress of the European Society for Radiotherapy and Oncology.

Just two radiotherapy sessions given over eight days can treat prostate cancer without any extra side effects

European Society for Radiotherapy and Oncology (ESTRO)
Reports and Proceedings

Two larger doses of radiotherapy for prostate cancer cause no additional side effects compared to the standard five doses of radiotherapy, according to results presented at the Congress of the European Society for Radiotherapy and Oncology (ESTRO 2026). Experts say the research brings us one step closer to safe and effective radiotherapy in only two out-patient sessions.

Long-term EORTC trial challenges assumptions about lymph node radiation therapy in breast cancer

European Organisation for Research and Treatment of Cancer
Peer-Reviewed Publication

Stockholm, Sweden, 17 May 2026 — Final results from a landmark EORTC randomised trial with more than 20 years of follow-up show that irradiation of the internal mammary and medial supraclavicular lymph nodes reduces breast cancer mortality but does not improve overall survival.

Tiny materials, stronger antitumor immunity

China Anti-Cancer Association
Peer-Reviewed Publication

Cancer immunotherapy has changed the treatment landscape, yet many tumors still evade immune attack by hiding antigens, blocking T cell entry, and building an immunosuppressive tumor microenvironment (TME).

Future doctors rally around children with cancer and their families at PBSTA Day

Duke-NUS Medical School
Meeting Announcement

More than a student event or hospital outreach effort, Paediatric Brain and Solid Tumour Awareness (PBSTA) Day has become a growing community of support for children living with cancer and the families who care for them.

Meeting an AI doctor before a real-life consultation improves cancer patients’ understanding and reduces stress

European Society for Radiotherapy and Oncology (ESTRO)
Reports and Proceedings

Cancer patients who interact with an artificial intelligence (AI) avatar doctor before they meet their real-life consultant feel more knowledgeable and less stressed, according to research presented at the Congress of the European Society for Radiotherapy and Oncology.

Blood test that detects tumour DNA could help guide treatment when cancer has spread

European Society for Radiotherapy and Oncology (ESTRO)
Reports and Proceedings

A blood test that detects tumour DNA circulating in the bloodstream may help select the most effective treatment options for cancer patients whose tumours have started to spread, according to one of the largest randomised controlled trials of its kind presented at the Congress of the European Society for Radiotherapy and Oncology.

ESTRO: Select breast cancer patients may be able to omit surgery following ablative radiation

University of Texas M. D. Anderson Cancer Center
Reports and Proceedings

A select group of patients with early-stage breast cancer were able to omit surgery with no tumor progression after three years, according to results of a Phase 2 trial of ablative radiation therapy and endocrine therapy led by researchers at The University of Texas MD Anderson Cancer Center.

ESTRO: ctDNA improves treatment monitoring for patients receiving metastasis-directed therapy

University of Texas M. D. Anderson Cancer Center
Reports and Proceedings

Analysis from one of the largest studies of its kind showed that circulating tumor DNA (ctDNA) testing provided new insights that could better guide treatment decisions compared to the current method of counting lesions for patients with early metastatic cancers, according to researchers from The University of Texas MD Anderson Cancer Center.

Cancer-causing protein also helps tumors repair their DNA

Oregon Health & Science University
Peer-Reviewed Publication

Researchers at Oregon Health & Science University found that the protein MYC, which is overactive in most human cancers, plays a direct role in fixing dangerous breaks in DNA. By helping cancer cells survive chemotherapy and other treatments that damage DNA, the protein may contribute to tumor resistance and poor patient outcomes.
