Researchers developing new colon cancer tests amid rising cases

TAMPA, Fla (WFLA) – With more than 200,000 cases of colon cancer diagnosed across the country every year, researchers are working on new ways to detect the disease better.

Colon cancer is the second leading cause of cancer deaths both in the U.S. and across the world. In recent years, doctors say they’ve seen a spike in cases among younger people. That includes patients in their 20s and 30s.

“The increase has become where now colorectal cancer is the most common cause of cancer death in men younger than 50,” said Dr. Jorge Marcet, the medical director of colorectal surgery at Tampa General Hospital.

Researchers are currently developing blood tests that can detect the cancer. The tests look for altered DNA associated with the cancer. One test, developed by New Day Diagnostics, is now approved for use by the FDA. Doctors say that and other blood tests could eventually become a standard screening tool.

“We hope that soon we may have a blood test not just colon cancer but other cancers,” said Dr. Jorge Marcet. “Once those tests are available, I imagine initially they’re going to be rolled out for patients who are very high risk. High-risk people would include those that have a strong family history of colon cancer.”

For now, doctors say a colonoscopy remains the best tool to detect colon cancer. It’s recommended people get their first screening at age 45, however those with a family history of the disease should begin screening earlier. Stool tests are another alternative for screening.

While colon cancer is one of the most common types of the disease, doctors say it’s also one of the most treatable if detected early.
