Screening FAQs

Q. How does screening save lives?
A. Screening for colon cancer works in two ways: first, by finding cancers early when treatment is most effective and second, by finding growths (polyps) inside the colon and removing them before they become cancer.
Q. If screening works, why aren't more people doing it?
A. Screening compliance rates are influenced by many factors, not least of which are:
- lack of public awareness about colon cancer and of the benefits of regular screening
- inconsistent promotion of screening by medical care providers
- uncertainty among insurance providers and consumers about insurance benefits and limitations on covered benefits
- characteristics of the screening procedures (e.g., imperfect tests, negative attitudes towards the screening procedures)
- absence of social support for openly discussing and doing something about "the disease down there"
Q. Why remove polyps if they are benign?
A. Colon polyps are important, since some may turn into colon cancer over time. While not every colon polyp turns to cancer, it is felt that almost every colon cancer begins as a small non-cancerous polyp. Fortunately, during colonoscopy these polyps can be identified and removed or destroyed--thus preventing a possible colon cancer. If a polyp is large enough, tissue can be retrieved and sent for biopsy to determine the exact type of polyp.
Q. What are my options for screening?
A. Thousands of lives could be saved every year if people followed recommended screening guidelines. There are many options for screening methods – we recommend that you talk to your doctor about which test is right for you. Learn more about who should be screened and when.
