	Cannabis compounds may weaken glioblastoma response to chemotherapy and radiation Several cannabinoids reduced chemotherapy- and radiation-induced apoptosis in glioblastoma cell models, with effects linked to reduced apoptotic priming, increased pro-survival signaling, and G1 cell-cycle arrest. The findings raise concern that cannabinoid exposure could interfere with some cancer treatments, although the results are limited to laboratory models and require in vivo and clinical validation.

	Optimal prostate-specific antigen cutoff linked to improved prostate cancer survival After treatment for metastatic prostate cancer, a drop in prostate-specific antigen (PSA) levels in the blood is an indicator that the treatment is working.

			Most veterans with low-risk prostate cancer choose active surveillance Three decades after UC San Francisco pioneered "active surveillance" for patients with low-risk prostate cancer, a new study has found that the vast majority of veterans with the diagnosis pursued this option instead of treatment.

			Ultra-processed foods linked to higher prostate cancer risk in men Ultra-processed foods (UPFs) account for nearly 60% of adults' and 70% of children's energy intake in the United States.

			Traditional prostate cancer features fail to predict hormone therapy benefit A new study led by investigators at the UCLA Health Jonsson Comprehensive Cancer Center found that while traditional pathological features used to classify aggressive prostate cancer -such as high-grade disease, cancer extending outside the prostate and cancer involving the seminal vesicles- after surgery can help identify patients who are more likely to have worse outcomes, they do not predict who will benefit more from adding hormone therapy to...

	Aircrews face highest risk of radiation-related cancer deaths Of more than 500 occupations in the United States, flight attendants and pilots have the highest and second-highest proportion of radiation-related cancer deaths, a new study has found.

	New study links chronic stress to immunotherapy resistance in tumors Immunotherapy has transformed cancer treatment, yet many tumors remain stubbornly resistant to its effects.

	New method enables more precise labeling of protein-protein interactions in cancer-specific cells Using a photochemically driven labeling technique, a Cornell University-led research group has devised a strategy for capturing cancer-specific protein-to-protein interactions, which could one day spawn targeted therapies for prostate, small-cell lung, pancreatic and other deadly forms of the disease.

	Study shows how prostate tumors rewire metabolism to resist therapy Prostate tumors can rewire amino acid metabolism to override the normal brakes on cholesterol production, a process that may fuel hormone therapy resistance, according to a study by Weill Cornell Medicine investigators.
