A new study suggests that a DNA-damaging gut bacterium may drive cancer development in patients with familial adenomatous polyposis (FAP), a rare inherited condition that causes hundreds of colon polyps and almost always leads to colorectal cancer if untreated.

Sellar chondrosarcomas are a very rare form of bone cancer occurring in the base of the skull, which are not only poorly understood but also frequently misdiagnosed. Now, researchers have explored the clinical outcomes of non-invasive surgical techniques for these tumors, while additionally exploring their diagnosis, treatment, and prognosis. They also provide valuable recommendations on using clinical and imaging data for accurate preoperative diagnosis of these tumors.
