Not necessarily. You may have a higher risk of developing colon cancer if your uterine cancer was caused by a certain genetic mutation. This mutation causes a condition called hereditary non-polyposis colorectal cancer (hnpcc). Patients with this have about an 80% chance of getting colorectal cancer and about a 50% chance of uterine cancer over their lifetime.
Increased risk. Having any cancer (aside from a skin cancer) increases the risk of a second cancer. Also, there are some family cancer syndromes (lynch syndrome or hnpcc) in which there is an increased risk for both colorectal cancer and uterine cancer, as well as some other cancers. Your physician can help you assess your risks in this area. He or she may also suggest you consult a genetic counselor.
Sometimes. There is a familial disorder known as lynch syndrome which increases both the risk of colon cancer and endometrial (uterine) cancer. About 5% of all colon cancers are caused by lynch syndrome. If a family has multiple cases of both colon and endometrial cancer or colon cancer under the age of 40, lynch syndrome should be considered.
No. No connection. However, treatment with radiotherapy may damage rectal tissues, andpotentially lead to induced cancer years later in a minescule proportion of survivors.
Why does having had endometrial cancer increase risk of colon cancer? I have lynch syndrome but risk would be high anyway?
You have not had. Enough or appropriate genetic counseling with regard to Lynch syndrome 1 or 2, to which you are cecertainly entitled. Find out which laboratory tested you for confirmation, by demanding a copy of your laboratory report, to which you are entitled, which will provide you with the number for the Genetics Counselor at that laboratory. He/she will explain the significance to you and for your relatives.
Depends on. Stage at diagnosis. Early cancers have excellent prognosis, whereas more advanced stages have poorer outlook. This is exactly why screening is important for this particular cancer.
Possibly. Poor dietary habits can lead to obesity as well as colon cancer.
Yes, & other cancers. The national cancer institute, on its website, lists several cancers whose risks are increased in an obese person. The cancers are: breast cancer in post-menopausal women (women after menopause), endometrial cancer (cancer of the uterus' lining), colon cancer, kidney cancer, and esophagus cancer (the tube that carries food from the mouth to the stomach).
Why do people become upset when I say if I get colon cancer im most likely going to refuse treatment?
Curable cancers. If yopu have to get cancer, this is the top 3 cancers you want to have: 1. Testicular 2. Colon 3. Breast they are very treatable and with good cure rates. #1 if for the guys, #3 for the girls, #2 for everyone. This way everybody is happy.
Unwise. If you ever get colon cancer in an early stage and refuse treatment, you would be choosing to die of a curable illness. It is certainly your choice but probably not a wise decision.
