NEW YORK – New guidelines released Wednesday recommend US adults start colon cancer screening, aged 45 instead of 50.
The American Cancer Society's Council disagrees with guidelines from an influential government advisory group that kept the age from 50 in an update two years ago.
Cancer Society officials acknowledge that switching to 45 physicians and patients could cause confusion, but they firmly believed that they needed to act now. The stakeholder group was influenced by their study, published last year, which found rising rates of colorectal cancer and death in people under 50 years of age. Experts are not sure why, since 1
guidelines are for men and women aged 45 to 75 years with an average risk of colorectal cancer; Recommendations are different for people with certain conditions, such as Crohn's disease or a family history of colorectal cancer. The group advocates six types of screening, from low-cost fecal tests, which are conducted every year, to colonoscopies, which are conducted every ten years.
"All of these tests are good tests, and the choice should be offered to the patient," said the Cancer Society of the Company. Rich Turners. "The best test is the test done."
The same tests are recommended by the US Preventive Services Task Force, a panel of evidence that provides evidence for a variety of screenings and treatments. It updates its colon cancer guidelines in 2016 and its next review is not expected until about 2021.
The panel's recommendations are driving what screening by insurance is covered under the Affordable Care Act, though 20 states have laws that cover the cancer to associate policies of the company. It is not uncommon for groups to have slightly different guidelines, although those for colorectal cancer have remained roughly the same for decades.
Most colon cancer occurs in adults 55 and older, and the good news is the case numbers and deaths have fallen for decades. Colon cancer, along with rectal cancer, is the second leading cause of cancer death in the US. This year, more than 140,000 Americans are expected to be diagnosed with it and about 50,000 die from it.
Doctors will probably pay attention to Specialized Medical Societies to sort out the various guidelines, Dr. Marcus Plescia from the Association of State and Territorial Health officials. But it may take a while for them to give clear advice.
Some experts have been worried about the risks of colorectal cancer 50 years ago in some ethnic and ethnic groups, and at least one gastroenterologist association has been pushing the screening of black adults at the age of 45 years.
Others argue that more efforts should be made to test more people, rather than reducing the age of routine examinations. Only about two-thirds of over-50s have followed the screening guidelines.
"It's hard enough to get people to even do it," Plescia said.
Dr. Andrew Wolf, the lead author of the latest guidelines, said they considered and rejected this reasoning.
"We should be able to do both," said Wolf, an internist at the University of Virginia.
