Colon Cancer is still the second leading cause of death from cancer in the United States despite numerous advances in screening and early detection. It is a disease that is found more commonly in black Americans with 46.7 cases per 100,000 individuals as compared to 38.9 cases per 100,000 individuals for Caucasian Americans. Death from colorectal cancer occurs in every 21.1 cases for African Americans and only 14.6 cases for white Americans.
Even with these dismal figures the cancer death rate from this disease has decreased by 22 percent over the last decade. We attribute this to increased awareness and increased screening.
All individuals should report a change in bowel habits to their doctor immediately. Blood stained stool is a cause for an immediate call to your physician. Generally at age 40 all adults should be having a digital rectal examination as part of a checkup. Stool occult blood slides or stool fecal immunoglobulin slides are used to screen for microscopic gastrointestinal tract bleeding. These tests involve placing a small smear of stool on a slide and submitting it to the lab where it is tested for microscopic blood loss. Usually a CBC or complete blood count is performed as well since gastrointestinal blood loss in small constant amounts usually produces a low blood count or anemia of the iron deficient variety.
Screening colonoscopies are recommended for all non-Black Americans at age 50. Due to the increased risk of colon cancer in Black Americans we recommend that they start screening colonoscopies at age 45. If you have a first degree relative who had colon cancer or precancerous polyps we ask that you start your screening at an age that is 10 years earlier than your relatives disease became apparent.
For those individuals unwilling to have a screening colonoscopy we can offer a CT Virtual Colonoscopy. The preparation is simpler than for a colonoscopy but the radiation dosage involved is equivalent to receiving ten years’ worth of chest x-rays all at once. If the virtual colonoscopy shows a polyp or a mass you will then need to undergo a traditional colonoscopy for biopsy and removal preceded by a traditional pre- colonoscopy bowel cleansing prep.
Cologuard is a new and attractive stool test that detects abnormal DNA associated with premalignant polyps and cancerous tumors. It is fairly new but readily available.
Numerous lifestyle choices can influence your development of colon cancer. Tobacco use is associated with an increased risk, as is drinking more than moderate alcohol. Red meat intake is associated with an increased risk of colon cancer with a 20% increase per 100 gram increase in red meat per day. Regular exercise and intake of high fiber food helps to decrease your risk of developing colon cancer.
March is colon cancer awareness month. Speak to your physician about your risk of developing this serious disease and ways to prevent it from developing. You can use the visit to establish your own personalized colon cancer screening surveillance schedule.
