[|Human|] Im worried i have hnpcc. grandmother: colon cancer age 66 (survived, died of heart disease age 76), father: adenomatous polyp(s) age 46, now age 64 but had a few more polyps on later colonoscopies, grandmothers brother stomach cancer age 75 (survived, i think died of alzheimers age 86). great-grandmother died of stomach cancer age 45-50, was not histologically confirmed. grandmothers other 4 brothers no cancer, one died of kidney failure in his 60s the other 3 are in their 70s, no cancer. i am a med student. i know cancer (stomach and colon) tends to set in in the 60s-70s in general population, but im worried b/c there is a clustering of GI cancers (and great grandmother died in her 40s)
[|AI|]  Hi, dairy have gone through your question. I can understand your concern.  You have family history of cancer.  You also have increased chance of gastrointestinal cancer.  Many genetic factors are responsible for this cancer development.  No need to worry.  Just be relaxed.  You should go for annual health check up and regular colonoscopy. So if you have cancer then you can detect at very early stage, and we can treat it better. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
