Well-Rounded Prevention May Lower Colon Cancer Risk

continued...

Sigmoidoscopy only examines the rectum and left side of the large bowel, or colon, whereas colonoscopy examines the entire large bowel. "The distinction is important," Antman tells WebMD, "because benign and cancerous tumors are distributed evenly throughout the colon."

Fortunately, nature also offers protection against colon cancer. "Aspirin and [nonsteroidal anti-inflammatory drugs] block the enzyme that activates cancer cells, but there are natural sources that do the same thing," says Mitchell Gaynor, MD, director of medical oncology and integrated medicine at the Strang Cancer Prevention Center in New York City. "The herb rosemary, the spice turmeric, the skin of red grapes, and green tea all have similar effects as the [nonsteroidal anti-inflammatory drug] Celebrex."

Janne was supported with a fellowship grant from the Friends of Dana-Farber Cancer Institute.
