Am I having any colon or stomach cancer risks by eating teen diet at college? Mom was strict due to cancer in the family.

Not really. Growing up in the western world is associated in with an increased risk of colon cancer. Stomach cancer is less common and is seen more frequently in asia and 3rd world countries, perhaps due to h.Pylori and genetics. Though associations with diet have been suggested, there is no direct evidence that you can affect your colon cancer risk by modifying your diet. A vegetarian diet may help.
