I am 14 yr old female, and my grandpa later during his life got cancer and died. IS it likely its been pass down to me?

Colon cancer is something that tends to run in families. However your diet has a lot to do with it. Since you have a history (although you didn't say your grandpa died from colon caner) you should start being screened when you turn 40. You only need to concentrate on living now not this illness. I have a history of this in my family, several members and I get checked once a year since I turned 40.

Not likely. Without much background on you, I would guess your chances of getting colon cancer are not much different than the average person.

There is a hereditary condition HPCC where the colon is full of benign polyps. This increases the risk of getting colon cancer. However, most colon cancers have no hereditary aspect.

BTW, no cancer is hereditary (except chrionocarcinoma given by mother to infant). Rather the an increased risk of cancer can be inherited. Cancer is a set of genetic mutations to genes that are involved in cell growth and genes that prevent abnormal cell growth (tumor suppressor genes). In most cancer cases, these genes are mutated during ones lifetime. When people talk about the hereditary aspect of cancer, they usually mean that they have mutated (deactivated) tumor suppressor genes at birth.

As for having a grandfather with colon cancer late in life, that is more reason to believe that there is no inheritable aspect. The older a person is the more likely he/she will get cancer. The reasons are two-fold. First, the longer you live the more exposure you get from carcinogens and the more opportunities for a cell to become cancerous. Second, elderly people usually have a weaker immunity system which is key to preventing cancer (There are cancers that only occur in those with compromised immune systems - Kaposi's Sarcoma in AIDS patients).

there's a high chance, you can minimize the risk by avoiding or Minimize eating foods that are fatty, salty, oily etc
try eating foods rich in fiber

colon cancer can also be influence by your diet
