It varies: Colon cancer can strike from the 20s and beyond, but is much more common in people in their 50s to 70s hence the recommendations to not routinely do colonoscopies in people before the age of 50. Colon cancer that presents before 60 is often genetic whereas after 60 is more likely due to environmental factors like smoking and red meat.

Colorectal Cancer: 90% of colorectal cancers strike after age 50, unless the person has a hereditary form such as familial adenomatous polyposis, or certain chronic diseases such as ulcerative colitis. There has been an uptick in recent years in cases in young people, and screening is recommended in those with a positive family history beginning at age 45. A colon cancer screening test is easy to obtain at any time.

Mesenteric nodes: As colon cancer grows from premalignant cells in the mucosa of bowel it invades the muscularis reaching serosal outer surface (Dukes B). It then invades nodes of the mesentery C1 expanding to 4 or more nodes C2 and then along the mesenteric lymphatics to liver. Subpopulations in the primary however can eventually spread directly to lung or bone depending on their surface antigens.

High fiber low fat: A diet rich in fiber and low in fat may reduce the risk of colon cancer. Screening colonoscopy at 40 or even earlier may be warranted with a strong family history. You should discuss the use of Aspirin or related drugs for prevention, with your doctor.

Unclear question: Before metastases, colorectal cancer affects the mucosa and wall of large intestine. Tumors on the left side of the colon are more common than on the right side. See this site for more info. http://www.ncbi.nlm.nih.gov/pubmedhealth/pmh0001308/.
