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).

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).

How exercise influences cancer cell viability

This interview uncovers how exercise may reduce cancer cell viability, with insights into adipose interactions and innovative 3D culture systems.

Study reveals why aging makes the body more vulnerable to breast cancer

Researchers at Georgetown's Lombardi Comprehensive Cancer Center have identified a mechanism that may help explain a key reason why older people experience worse outcomes from breast cancer.

15 May 2026

Researchers develop pH and redox-sensitive systems to reduce immunotherapy toxicity

Although cancer immunotherapy has transformed treatment by harnessing the immune system to eliminate tumors, only a small subset of patients benefit. Many solid tumors remain "cold," characterized by poor immune cell infiltration and resistance to immune checkpoint blockade (ICB).

Gene panel predicts chemotherapy response in triple-negative breast cancer

Researchers at The University of Texas MD Anderson Cancer Center have characterized cancer cell-specific features in the tumor microenvironment (TME) of early-stage triple-negative breast cancer (TNBC) tissues, identifying specific macrophage subtypes associated with chemotherapy response.

Adult weight gain strongly linked to higher obesity-related cancer risk

New research presented at this year's European Congress on Obesity (ECO 2026) in Istanbul, Turkey (12-15 May) shows that people who gain the highest amount of weight across adulthood are at greatly increased risk of certain obesity related cancers.

13 May 2026

Could GLP-1 drugs help breast cancer patients live longer?

A large retrospective cohort study of adult female breast cancer patients found that GLP-1 receptor agonist use was associated with better all-cause survival and recurrence-free survival in patients with obesity or type 2 diabetes. The strongest associations were seen versus non-use in obesity and versus insulin or metformin in type 2 diabetes, while comparisons with SGLT2 inhibitors were less consistent and require further study.

Cedars-Sinai develops AI tool for faster and cheaper tumor analysis

A team led by Cedars-Sinai Health Sciences University investigators has created a faster, cheaper way to determine the genes expressed in cancerous tumors.

New study reveals how slow-growing cells drive breast cancer relapse

A new study by the Garvan Institute of Medical Research has uncovered a hidden mechanism explaining why breast cancer can return many years after successful treatment.

Copper-based nanoplatform shows promise against metastatic tumor growth

What happens if cancer cells lose both their mitochondrial energy supply and their glycolytic backup system? This question is central to a new study published in Research by researchers from Northwestern Polytechnical University and collaborating institutions.
