I've had 4 colonoscopies in 20 years and will continue to have them, as both my mother and my sister have had colon cancer. My mom was very lucky; she was 70 years old and her tumor type was so contained and small that basically even chemo was optional after the surgery to remove the tumor. She did the chemo and was fine. My sister? She was diagnosed with colorectal cancer, with 7 nodes involved, at the age of 31. She had a weekend to determine the rest of her life. Her surgical option was to have her entire lower digestive system removed (about 3 feet of large intestine as well as rectum/anus) and wear a bag for the rest of her life, or have the surgery and spend her life incontinent. In addition, she and her husband needed to decide if she wanted to postpone surgery, take high doses of estrogen so that the doctors could collect ova, fertilize those ova and freeze them, if they wanted to ever consider having a family. That is a LOT for a 31 year old (and her 26 year old husband) to face and determine in a 48 hour time span, and they decided that she'd have the surgery and opt for the colostomy, and that they wouldn't be having children. Ever. Chemotherapy and radiation were brutal, and as she also has cerebral palsy, she was unable to walk for quite awhile due to the muscle wasting and not having the strength to manage crutches. Rehab also wasn't pretty, but PT was necessary to regain mobility. The upside? She's a 20 year cancer survivor- so it was definitely the right decision!
If you need a colonscopy, please have one. Don't let the statistics scare you. Don't let the idea of discomfort or embarrassment deter you. What convinced me, finally, to have the first colonoscopy? I just couldn't figure out how I'd be able to look my daughter in the eye and say, "Sorry, mommy's going to die because she was afraid and embarrassed to have a simple test."
