Depends: 20% are genetically caused, the remainder being environmentally caused by some as yet unknown combination of exposures to various agents. The person who finds the actual answer will no doubt be on a south pacific island relaxing after having won the nobel prize. We just don't know in every case.

Combination : Environmental and genetic factors can increase the likelihood of developing colorectal cancer. 70% of cases are sporadic cases, only about 10% is a true inherited cancer and approximately 25% is familial type. Some risk factors include- inflammatory bowel disease, dietary habit ( processed red meat), dm, alcohol, growth hormone, obesity, cigarette, immunosupressant , age, etc.

Colon cancer: Nobody know for sure. However, recent studies showed genetic mutations in tumor suppressor gene such as apc can be detected in majority of sporadic colon cancer, while dna repair gene mutation account for some high risk colon cancer syndromes known as lynch syndrome. The risk factors include die (fat), alcohol/smoking, prior polyps, ibd, and family history, etc.

Very complicated: Monoclonal theory says that just like we are a living thing, we are born, we have jobs to do and then we die, each cell has a similar cycle of birth, life, and death. Cancer occurs when a cell develops so many mutations that it does not follow that cycle and does not die but can still divide itself and hides from our immune system which is there to detect abnormal cells and destroy them.

Rectal bleeding is c: Colon cancer can be entirely silent disease, producing little or no symptoms when early and localized to the bowel. So screening with colonoscopy in asymptomatic subjects is advised to look for polyps which are precursors of colon cancer. Rectal bleeding and abdominal pain can be symptoms of this cancer but they are often not early symptoms. The cause of colon cancer is not known.

Unknown: Uncertain as to what exactly causes any cancer, which is non-stop cell growth. Some risks are genetic, some are related to obesity, eating too much fatty foods, eating too much meat and not enough fruits and fibers, cigarette smoking, etc.

IBD, viruses: Colon cancer probably begins from the effect of exogenous factors on the bowel, considering that the patient does not have hereditary causes. A virus such as polyoma is probably a contributing factor along with carcinogens in the food. In addition patients with inflammatory bowel disease release, over a long period of time cytokines that can induce malignant transformation.
