Digital rectal examination is not useful to early detect prostate cancers

A new study suggests that digital rectal examination (DRE) is not a reliable screening tool for early prostate cancer detection. Researchers found that DRE missed many cancers in their early stages, with only 3 out of 57 suspicious cases detected. This method was compared to PSA testing, which detected four times more prostate cancers.

Two-pronged immunotherapy eliminates metastatic breast cancer in mice

Researchers identified a way to treat surrounding breast tumors that have spread to bone, making them vulnerable to the immune system's attack. Boosting T cells and macrophages eliminated metastatic breast tumors in mice, suggesting a new approach for treating bone-spreading breast cancers.
