"We are all confused and bewildered," says Mark Pochapin, MD, a professor of medicine and director of the Department of Gastroenterology and Hepatology at New York University's Langone Health.
The study concerns even more information It has been found that the likelihood of late-stage disease is nearly 60 percent higher in older people than the age of 55 years. "When a 25-year-old complains of blood in the stool or a sudden change in bowel habits, the family doctor rarely thinks that it may be cancerous, and does not offer check-ups to diagnose the problem, such as a colonoscopy , "Explains Edith Mitchell, MD, Program Director for Gastrointestinal Oncology at the NCI-designated Sidney Kimmel Cancer Center at Jefferson Health in Philadelphia. "Therefore, they are diagnosed much later. But it's amazing how many young patients we have now. I would say that today about 40 percent of my patients are under 50 years old.
Colon cancer or rectal cancers in younger adults are often attributed to other risk factors, such as: As an inflammatory bowel disease (Crohn's disease or ulcerative colitis) or a genetically inherited gene syndrome such as Lynch syndrome. However, experts say that for many of the younger people, there is no clear reason why they occur.
"The increase in colorectal rates in younger adults has been in line with the increase in the obesity epidemic that is a factor," said David Liska, MD, a Cleveland Clinic bowel surgeon. "Many of the risk factors for obesity are also risk factors for colon cancer, including a high-fat diet rich in red meats and low vegetables and sedentary. However, I see many younger patients of normal weight and healthy lifestyle, so there must be other reasons. "
One theory says that changes in the microbiome – the bacteria in your digestive tract – can also be a factor. "Younger adults may have been exposed to many antibiotics as children and eat more processed foods than their parents," notes Pochapin. "That, in turn, may have altered gut bacteria in ways that make cancer cells grow."

The two major familial conditions that increase the risk of colorectal cancer are familial adenomatous polyposis (FAP), in which hunts occur. Dred polyps cover the inner lining of the colon and Lynch syndrome. However, there can be many other genetic mutations that increase the risk of colorectal cancer that we do not know about, Liska notes. "Data-reactid =" 30 "> Up to 35 percent of people under the age of 35 diagnosed with colorectal cancer has a genetic mutation, compared with about five percent of all cases of colorectal cancer, according to a 2015 study published in Journal of Clinical Oncology was published: "There is more and more evidence that colon cancer in younger people is possible to be genetically different than colon cancer in the elderly," adds Liska. The two major familial conditions that increase the risk of colorectal cancer are familial adenomatous polyposis (FAP), in which hundreds of polyps cover the inner lining of the colon and Lynch syndrome. There could be many other genetic mutations that increase the risk of colon cancer We do not know anything yet, Liska notes.
If you have colon cancer or colonic polyps in the family, you should consult with a genetic counseling consultant, advises Joy Larsen Haidle, spokeswoman for the National Society of Genetic Counselors. You can see if it makes sense for you to do genetic testing to see if you have one of the most common colorectal cancers that cause genetic mutations.

According to a study published in the International Journal of Cancer of 2018 (2019003), there is a greater chance of developing colorectal cancer In published in JAMA Oncology revealed that women over the age of 20 were 30- and 40-year-olds who were either overweight or obese, had up to twice the risk of developing colon cancer before the 50's. Compared to normal-weight women. "Data-reactid =" 33 "> People who are overweight before the age of 30 have a higher chanc e, to develop colorectal cancer later, according to a report from 2018 published in the International Journal of Cancer . Another 2018 study from JAMA Oncology found that women in their 20s, 30s and 40s, who were either overweight or obese, were up to twice as likely to be at risk before the age of 50 Colorectal cancer, compared with normal weight women.
It is also important to eat a diet that is high in fruits, vegetables and whole grains, and one that contains little red or processed meat adds pochapin. All of these steps have also shown that they reduce the risk of colon cancer, move regularly, do not smoke and limit alcohol.
The American Cancer Society recommends now all adults, at the age of 45, to start a colorectal cancer screening. The Gold Standard is a colonoscopy – a test that uses a flexible, lighted tube for your doctor's examination For polyps in your rectum and large intestine during sedation – You can also perform a screening test at home, the so-called immunological fecal test (FIT ), which checks for hidden blood in your stool. (Remember, if you have a positive test result, you need to colonoscopy.)
However, if you have colorectal cancer in the family, you may need to start earlier: "We recommend starting at the age of 40 or 10 Years younger than the youngest person in the family was diagnosed with cancer, "explains Pochapin.

Most younger adults who have been diagnosed with colon cancer develop first in the lower part of the intestine, which is usually called rectal bleeding expresses, notes Pochapin. "Any rectal bleeding should be taken seriously and requires a colonoscopy," he stresses.
However, you should also watch for changes in bowel function – that is, diarrhea or constipation that lasts longer than a few days. "One of the common signs is that the chair is getting thinner and thinner, almost like a pencil caliber," adds Pochapin. "This is because colon cancer narrows in the gut."
If you feel your doctor ignores your concerns, get a second opinion. "My 15-year-old patient complained for months about symptoms and was repeatedly reminded that it was due only to her onset of menses," says Mitchell. "She was diagnosed correctly when she ended up in the emergency room and had to be operated on immediately."
