Doctors believe most colon cancers develop in colon polyps. Therefore, removing and preventing the development of colon polyps may also prevent colorectal cancer. Polyps may be small and produce very few symptoms. Having colonoscopies done regularly can help identify cancerous polyps. Signs of colon cancer include bowel habit changes, blood in stool, abdominal pain, weight loss, fatigue and persistent cramping. Risk factors include age, polyps of the colon, diet, heredity, smoking, alcohol and environmental factors. Those who are over age 50, have a diet high in red meats, smoke, drink and a family history of cancer increases the possibility of getting colon cancer.
PREVENTING POLYPS: A new combination of drugs has been shown to reduce the risk of colon cancer by preventing the recurrence of polyps. The treatment combines a low dose targeted cancer-fighter known as diflouromethylorinithine (DFMO) with a non-steroidal, anti-inflammatory drug known as sunlindac (NSAID). In a study of the therapy, 375 patients with a history of at least one colorectal polyp were randomly assigned to either the drug treatment or placebo treatment. For three years, doctors monitored these patients to measure polyp reoccurrence. Results of the study were promising. Doctors found it reduced the risk of recurrent colorectal polyps by up to 95 percent. "It's the first example of a combination chemo prevention for cancer that really works," Eugene Gerner, Ph.D., director of the Gastrointestinal Cancer Center at the Arizona Cancer Center in Tucson, Ariz., was quoted as saying. "This trial is the biggest possible prevention ever detected for any cancer trial."
