Cancer answers: Are all colon polyps cancerous?

Written by Community Health Network on 3/11/2014 7:00:00 AM

Dr. Agarwala is a medical oncologist and certified MD Anderson Cancer Network® physician.

The short answer is no. Not all polyps in the colon are cancerous, nor will all polyps turn into cancer. A majority of polyps are asymptomatic and are caught on screening colonoscopies.

More often than not, these polyps are removed at the time of the colonoscopy and no further treatment is needed, except for ongoing colorectal cancer screening.

What is a colon polyp?

Written by Community Health Network on 3/5/2014 6:00:00 AM

A colon polyp is a small clump of cells that forms on the lining of the colon. Although most colon polyps are harmless, some become cancerous over time.

Anyone can develop colon polyps. But you're at higher risk if you're 50 or older, are overweight or a smoker, eat a high-fat, low-fiber diet, or have a personal or family history of colon polyps or colon cancer.

Usually colon polyps don't cause symptoms. That's why it is recommend that people receive regular colon screenings. Colon polyps that are found in the early stages can usually be removed safely and completely.

Sedentary men at greater risk for reoccurring adenomas

Written by Community Health Network on 11/3/2013 9:00:00 AM

(Medical – October 30, 2013) Sedentary men are at greater risk for developing reoccurring adenomas or polyps, which are benign tumors in the colon or rectum known to be precursors to colorectal cancer, according to Columbia University medical researchers presenting their study at the 12th Annual AACR International Conference. 

"Sedentary behavior is emerging as a risk factor for poor health," said Christine L. Sardo Molmenti, PhD, MPH, Columbia University. "Even among those who fulfill daily recommendations for physical activity, lengthy periods of sedentary behavior have been associated with early morbidity and mortality, leading to the 'active couch potato' paradigm.” The physicians suggest reducing prolonged sitting time.

Family history of polyps significant factor in colorectal cancer

Written by Community Health Network on 11/2/2013 9:00:00 AM

(US News & World Report -- October 25, 2013) Cancer researchers at the Huntsman Cancer Institute at the University of Utah say even distant relatives have a higher colorectal cancer (CRC) risk, but up to 10 percent of CRCs are being missed by current colorectal cancer screening guidelines

Family history of adenomatous polyps is a significant risk factor for CRC. They analyzed 126,936 patients between the ages of 50 and 80. All had a colonoscopy screening: 43 percent had adenomas (polyps) and 4 percent had advanced adenomas.

Overall, the reported CRC risk is greatest for first-degree relatives (35-70%) who have polyps, but second and third-degree relatives also have a smaller but significant increased risk. 

"The biggest surprise was the percentage of missed cancers under the current guidelines. We figured there would be a few percent, but 10% is a large number,” said the study’s author Dr. N. Jewel Samadder. "Our results support the current screening guidelines, but they also raise the issue of whether some level of more aggressive screening should be considered, not only for first- degree relatives of patients with polyps diagnosed at or below age 60, but also for those first- degree relatives of patients diagnosed above age 60."

Live colonoscopy: Q/A with Dr. Narayanan, colon and rectal cancer specialist

Written by Community Health Network on 10/31/2013 12:00:00 PM

On October 29, 2013 during a live 30-minute colonoscopy procedure, Dr. Shekar Narayanan, colorectal surgeon at Community Health Network, answered questions about colon and rectal cancer and why it’s important to have a colonoscopy if you are 50 years and older - or earlier if you have a family history of colorectal cancer.

Patient Tami Schwenk of Columbus, IN, whose father is recovering from colon cancer, felt having a colonoscopy is a common sense thing to do and encourages others to take time to prevent the third most common  cancer for men and women and the second leading cause of cancer deaths. One in 20 adults are at risk for developing colorectal cancer. Watch videos: More about Tami and her history >>

Tami prepped the day before, drinking a solution throughout the day to clean out her large intestine. Dr. Narayanan said as he observed her colon during the colonoscopy, her overall prep condition was fair, but not excellent. There were sections of Tami’s colon that could not be observed with the digital camera/scope that traveled from her rectum through the large intestine/colon to the start of the small intestine. The folds in the lining of her colon are normal, said Dr. Narayanan. In the rectum, a hemorrhoid was observed. With her family history and this being her first colonoscopy, he would recommend a repeat colonoscopy in five years instead of 10 years as part of her best practices. continue reading ...
