When it comes to the colon, there are two main conditions that are considered precancerous – adenomas and hereditary colorectal syndromes. While they’re not thought to be cancerous, these conditions indicate abnormal changes to cells that may eventually become colorectal cancer. That’s why it’s important to watch out for all signs of colon cancer, especially precancerous colon conditions, so your RCCA cancer specialist can help catch and monitor any potential conditions when they’re most treatable.
If left untreated, adenomas, otherwise known as adenomatous polyps, can develop into cancer. These abnormal growths can be found attached to the lining of either the colon or rectum. There are three main types of adenomas, including tubular, villous and tubulovillous, and they’re used to differentiate between varying growth patterns. Villous adenomas are most likely to develop into colon cancer. While most adenomas will not cause any symptoms, some may cause:
- Bowel habit changes, such as mucus in the stool
- Rectal bleeding
Signs of Hereditary Colorectal Syndromes
Though rare, hereditary colorectal syndromes can cause colorectal polyps, increasing a patient’s chances for developing colon cancer. These syndromes include familial adenomatous polyposis (FAP), Peutz-Jeghers syndrome, Lynch syndrome and juvenile polyposis syndrome. Those with hereditary colorectal syndromes may notice the following symptoms:
- Changes in bowel habits
- Rectal bleeding
- Abdominal pain or discomfort
- Bowel obstruction
Diagnosing Precancerous Colon Conditions
At Regional Cancer Care Associates, we can order a variety of tests, such as colonoscopies, biopsies, genetic testing, flexible sigmoidoscopies and CT colonography, to diagnose precancerous colon conditions. If an adenoma is found, our highly credentialed physicians will help create a treatment plan that works for you. In most cases, precancerous polyps can be removed during a polypectomy.
