Edna, age 55: My grandmother died of colon cancer, so I think I am going to have a colonoscopy. I know that colonoscopy may have slightly greater risks of complications than a barium enema or sigmoidoscopy. However, I would rather have a colonoscopy to make sure I don't have cancer.

Jose Luis, age 54: I've had a fecal occult blood test every year, and now I'm going to have a sigmoidoscopy. I am a little worried and embarrassed about having a sigmoidoscopy, but I would rather be a little embarrassed than have colon cancer.

Frank, age 52: If I have to have an uncomfortable, embarrassing test, I would rather have one every 10 years than have one every 5 years. Besides, a colonoscopy examines the entire colon, not just part of it.

Stella, age 58: A sigmoidoscopy is a good way for my doctor to look for signs of cancer. I know it can't be used to look at the whole colon, but I feel comfortable that it will detect any problems.

Patrick, age 56: No one in my family has ever had colorectal cancer. I try to eat a balanced diet and get plenty of exercise. I am going to do yearly fecal occult blood tests. I am more comfortable doing that than having other more costly procedures.

Joycelyn, age 50: My mother has had colon cancer and my sister was recently diagnosed with breast cancer. I plan to have a colonoscopy and ask my doctor how frequently I should repeat the test. I am worried about my family history and want to do everything I can to avoid colorectal cancer.
