In brief: Bowel Cancer
Bowel cancer can be associated with a hereditary disease - familial adenomatous polyposis - an, in addition, there are families in which bowel cancer runs, striking members at an earlier age than the usual 50+ onset.
If there is colo rectal cancer in your family, it is best to undergo a simple screening test at your age, even though you are below the age when colorectal cancer usually strikes.

In brief: Somehow yes
There is some genetic predisposition in families with hx.
Of colorectal cancer. Diet also plays a rol ( low fiber diet increases cancer). Familiar poliposis increases chances of colon cancer. Colon polyps may degenerate in cancer. Small intestine cancers are rare and difficult to find. In general there are families affected by cancers and families affected by atherosclerosis but both together too.
