The American Cancer Society came out last week with the recommendation that screening for colon cancer start at age 45 instead of 50. This was based on the fact that people are developing colon cancer at an earlier age than they used to. Screening recommendations vary over time – for example: the flexible sigmoidoscopy used to be a recommended option to be done every 5 years – but this isn’t done as much now since it only allows the doctor to see the left half of the colon, and there has been an increase of cancers on the right side of the colon over time.
It is not uncommon for screening bodies to disagree – for example recommendations for screening for breast cancer and prostate cancer vary across these agencies. There is also a difference in how strong recommendations are. The American Cancer Society rates this new recommendation as “qualified” or less strong than their recommendation for screening for those 50-75 yo. The U.S. Preventative Services Task Force, American Academy of Family Physicians and American College of Gastroenterology currently still recommend starting screening at age 50 for someone who is not at increased risk. The new recommendations by the American Cancer Society were made after looking at data that showed a trend of cancer developing earlier than it used to. Click here to get a link to the study.
It is one thing for an agency to make a recommendation, it is another thing for a patient to get it paid for. At this time it would be unlikely for insurance companies to pay for a screening colonoscopy in a 45 year-old without other risk factors. It is also important to remember that these recommendations are about screening tests – which implies that the person doesn’t have any symptoms – no rectal bleeding, abdominal pain, stool changes, etc. that are concerning. If a person has any symptoms, then it would not be a screening test, but rather a diagnostic test and none of the above recommendations would apply.
While screening 45 year-olds for colon cancer may not be routinely covered at this time, there are behavioral changes people can make to decrease their risk. Colon cancer is associated with cigarette smoking; excess body weight; a lack of physical activity; and an unhealthy diet, including a lot alcohol and red or processed meat, and lacking fruits/vegetables, dietary fiber and calcium. Making these healthy changes can decrease risk of colon cancer and as well as many other cancers and chronic diseases. If someone believes that they need screening for colon cancer earlier than 50 years-old, it would be a good idea to speak with their doctor.
There are a large number of people in their 50’s who haven’t gotten colon cancer screening yet. Hopefully by seeing that there is a shift towards recommending screening at an even younger age, people from 50-75 years- old will be more likely to go ahead and get screened and get the benefit of early detection or prevention of colon cancer.
