Dear OncoLink "Ask The Experts,"
I was diagnosed with colon cancer at age 36, but have no family history of it. I am concerned for my 2 small children. When should my children start screening for colon cancer?
Carmen E. Guerra, M.D., M.S., Associate Professor of Medicine at Penn Medicine, responds:
Your young age at diagnosis is concerning for a familial or inherited predisposition for colorectal cancer. Currently, we can check for several colorectal cancer genetic syndromes, which include Lynch Syndrome [also called Hereditary Non-Polyposis Colorectal Cancer (HNPCC)] and FAP. You should discuss with your physician whether these tests are appropriate for you and, if you have a genetic predisposition, consider discussing whether the tests are appropriate for your children. Screening recommendations will depend on whether your family is affected by these conditions.

Oct 1, 2014 - The risk of colorectal cancer in first-degree relatives of colorectal cancer patients increases if the tumors are defective in repairing their DNA and if patients developed disease early, but most of the excess risk cannot be accounted for by defects in known genes, according to research published online March 23 in the Journal of Clinical Oncology.
