Colon cancer prevention facts
- Colon cancers may be both curable and preventable if detected early and treated.
- Screening for colon cancer in asymptomatic people is recommended to begin at age 50.
- Risk factors for colorectal cancers include a family history of colorectal cancer, genetic factors and certain lifestyle choices.
- Colonoscopy and flexible sigmoidoscopy may treat and/or prevent colorectal cancers safely and effectively; the new Cologuard test also may detect early precancerous and/or cancers of the colon safely and effectively, and thus allow invasive colonoscopy to become more of a treatment modality instead of a "test and treat if necessary procedure."
- Treatments of patients to prevent colorectal cancer that may be effective in some individuals but may have long-term adverse side effects include any NSIAD therapy.
- The use of two antioxidants, vitamins A and C, are apparently ineffective in reducing the incidence of colorectal cancer.
- People with hereditary colon cancer syndromes should consider genetic testing
- Genetic testing and counseling can help determine the possibility of early-onset of colorectal cancers and allow early treatments.
- Lifestyle changes (high fruit/fiber diet, no smoking, weight loss, screening and genetic testing in some individuals) may help reduce and/or possibly even prevent some people from developing colorectal cancers.
