Dr. Alessandro Fichera talks about prevention and early detection of colorectal cancer. Dr. Fichera is a surgeon and Director of Colorectal Surgical Oncology at the University of Washington and SCCA. Dr. Fichera stresses that colon and rectal cancer can be detected early and even prevented through routine colonoscopies. Pre-malignant stage polyps can be found and removed. Current low fiber and high fat diets increase many problems, including promoting colorectal cancers. Everyone should have a colonoscopy by the age of 50. First degree relatives of patients with colorectal cancer or polyps should have a colonoscopy by age 40. Earlier colonoscopies are recommended for individuals with a known mutation for familial polyposis, lynch syndrome, or other genetic predispositions.
