T3nomo colon cancer stage 2a had perforation is that high risk?

Dr. Leon Katz Dr. Katz
3 doctors agreed:

Partially yes: The staging information is generally favorable. The T3 (liothyronine) means that this tumor was involving the bowel wall but not the surrounding organs and this may have contributed to the perforation during the dissection. My advise is when you see an oncologist, make sure to point out this information. Even though you are node negative, the oncologist may be more willing to recommend chemotherapy to be safer. ...Read more

Is colon cancer and olvarian cancer often related?

Is colon cancer and olvarian cancer often related?

No: Colon Cancer is induced for the most part in non hereditary disease by viral transfection. The most common organism is the polyoma virus. Ovarian cancer is not derived from this viral event. Colon cancer begins in the mucosa of the bowel where ovarian Ca is an epithelial disease similar to that of peritoneal carcinomatosis. The only relationship is when colon metastasizes to ovary. ...Read more

Mom died of colon cancer, all 4 of dad's sis had breast cancer or precancer. 1 of the sis tested negative for cancer gene. Do I have elevated risk?

Yes, you do: First, i'm sorry to hear about your mom. That's so hard. And it's hard to worry about your own risk. You do have a higher risk of cancer, and it is probably not due to the breast/ovarian cancer gene (brca). Lynch syndrome is more likely. I can't tell you your exact risk because that depends on the age of your mom and your aunts when they were diagnosed. Tell every doctor this history from now on! ...Read more
