These two polyp types may represent separate cancer pathways that can occur at the same time. Nearly half of patients with serrated polyps also had adenomas, making this high-risk combination more common than expected. The results emphasize the importance of early detection and regular colonoscopy monitoring.

New research finally explains why. Scientists discovered that these T cells aren’t all the same: one subtype actually helps keep tumors in check, while another shields cancer from immune attack. The balance between these “good” and “bad” cells can determine whether a tumor grows or shrinks.

Researchers from the Francis Crick Institute and Vividion Therapeutics discovered a compound that blocks the signal telling cancer cells to grow and divide. The treatment worked in mice with lung and breast tumors and didn’t cause harmful side effects seen in earlier drugs. Now entering human trials, this breakthrough could open the door to safer, more precise cancer therapies.

Researchers from the University of Cambridge identified that the hormone INSL5 spikes when bile acid reaches the colon, triggering intense diarrhea. Their discovery not only sheds light on the biological cause of symptoms but opens the door to a diagnostic blood test and new treatment options, including a surprising existing drug that blocks this hormone’s effects.

Scientists report that exposure to colibactin in early childhood imprints a distinct genetic signature on the DNA of colon cells -- one that may increase the risk of developing colorectal cancer before the age of 50.
