Im worried i have hnpcc. grandmother
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.
