New study highlights importance of family history-based screening for colorectal cancer
Colorectal cancer, which develops in the large intestine, begins with small, noncancerous clump of cells, known as polyps, that form on the inside of the colon and turn cancerous over time. Regular screening tests can help prevent the disease by identifying these polyps so they can be removed.
But not everyone is screened early enough — and a new study underlines the importance of taking family histories of the disease into account.
