Blocking sugar modification could boost breast cancer immunotherapy success

Immunotherapies such as so-called checkpoint inhibitors activate the body's own immune system to fight cancer cells and have revolutionized the treatment of many types of tumor.

Study unravels mystery about why physical forces slow cancer growth

Researchers have solved a long-standing mystery about why physical forces slow cancer growth – and the answer could reshape how the disease is treated.

Roswell Park scientists present five key cancer studies at clinical meeting

The research findings of experts from Roswell Park Comprehensive Cancer Center will be featured during the American Society of Clinical Oncology (ASCO) annual meeting May 29 to June 2 at McCormick Place in Chicago.

Smaller tetraploid cells drive more aggressive cancer

Megan Sweet slices tumors. A normal day in the lab finds the Virginia Tech graduate student with hands deep inside a refrigerated metal box, pulling a mounted mouse-grown tumor incrementally closer to a razor-sharp blade.

Researchers link surgical weight loss to reduced female cancer mortality rates

Substantial and sustained weight-loss has been linked to a reduced risk of cancer and cancer-related death, mainly in women. Two new studies now provide clues to why the risk is reduced - and suggest that gender, metabolism and genetics may play a crucial role.

Targeting lipid enzymes triggers starvation states in aggressive tumor cells

While many American adults are trying to reduce cholesterol levels, certain cancerous tumors have a relentless appetite for the metabolite.

Explainable AI could make breast cancer drug predictions safer and clearer

AI-driven genomic analysis could help researchers identify existing drugs that may be repurposed for subtype-specific breast cancer treatment. The review proposes an interpretability-driven framework that links multi-omics data, mechanistic validation, and clinical translation to make AI predictions more transparent and clinically useful.

Excess EXO1 protein may drive cancer DNA damage and treatment response

When it comes to cancer, tumor suppressor genes are usually thought of as the "good guys." These genes make proteins that protect and repair DNA in cells.

Light-driven nanomotors improve multimodal breast cancer treatment efficacy

The nanomotor starts with bowl‑shaped mesoporous polydopamine (PDA) nanoparticles. These biocompatible bowls are loaded with two key payloads: Fe(II) ions as a Fenton catalyst, and BNN6, a thermally sensitive NO donor.

Spatial modeling of tissue compartments predicts breast cancer treatment response

HER2-positive breast cancer accounts for about 20% of breast cancer cases and is generally associated with more aggressive behavior and a higher risk of distant metastasis, while pathologic complete response (pCR) after neoadjuvant chemotherapy is strongly linked to better survival outcomes.

Study reveals cellular mechanisms driving resistance to targeted cancer therapies

Despite impressive innovations in medicine, most advanced-stage cancers still carry a grim prognosis. Developing more effective treatments requires a deeper understanding of the cellular processes that drive the formation and growth of common cancers.

Vitamin D deficiency linked to higher postoperative breast cancer pain

Vitamin D deficiency is associated with more moderate to severe pain following breast cancer surgery and an increased consumption of opioid drugs, finds research published online in the journal Regional Anesthesia & Pain Medicine.

Molecular profiling initiative seeks to uncover late breast cancer recurrence mysteries

The ECOG-ACRIN Cancer Research Group (ECOG-ACRIN), in collaboration with the SWOG Cancer Research Network (SWOG), has launched a new initiative to analyze paired original and recurrent tumor specimens from two practice-changing breast cancer clinical trials.

Young cancer survivors frequently report long-term sexual problems

Many young adults who have been treated for cancer experience sexual problems. This is shown in a doctoral dissertation at Karolinska Institutet, which also highlights gaps in information provided by the healthcare system.

Common allergy medication may also help fight aggressive cancers

A drug widely used to treat asthma and allergies may also help fight aggressive cancers, reports a new Northwestern Medicine study that uncovered how tumors hijack common white blood cells to evade immunotherapy.

DNA-guided CRISPR system targets RNA and expands Cas12 beyond gene editing

Researchers developed ΨDNA, a DNA-based CRISPR guide that allows Cas12 enzymes to target RNA with high specificity while retaining compatibility with DNA-editing workflows. The platform detected HCV RNA in clinical samples and enabled programmable RNA knockdown, multiplex targeting, and RNA modification in human cells.

Blood test detects tumor DNA to guide advanced cancer treatment

A blood test that detects tumor DNA circulating in the bloodstream may help select the most effective treatment options for cancer patients whose tumors have started to spread, according to one of the largest randomized controlled trials of its kind presented at the Congress of the European Society for Radiotherapy and Oncology (ESTRO 2026).

18 May 2026

Research offers clearer genetic blueprint of breast cancer variants

A study led by Dr Jason Pitt, Principal Investigator at the Cancer Science Institute of Singapore (CSI Singapore), has identified eight new "signatures" of DNA patterns (gains and/or losses) in breast cancer.

Targeted radiotherapy may delay progression in metastatic breast cancer patients

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 (ESTRO 2026).
