Depends. Inherited forms of colon cancer, e.g., apc and hnpcc have a near 100% risk. Having a family history, without defective genes, increases the risk but no where near 100%.
How probable would colorectal cancer be at 22 with no family history or risk factors. I always have a fear of cancers and make up symptoms in my head.
Quite low. BUT not impossible. Regular checkups, rectal exam and stool for blood testing are sensible In females, lung and breast are more common. American Cancer Society has prevalence listing. No SMOKING, limited alcohol, good diet and weight management can be your focus!
Low risk. The risk of colorectal cancer for a 22 year old person with no family history is low. Typical symptoms which would warrant investigation include rectal bleeding and a persistent change in bowel habits. Routine screening colonoscopy should begin around age 50.
Depends on family. You should see a clinical geneticist to document your family history of colon cancer and look for associated symptoms (e.g., dark skin, eye, tooth changes in gardner syndrome). The family pattern (e.g., autosomal dominant or multifactorial) and type of colon cancer (usual older age or early onset as cancer syndrome) will guide testing (blood sent to labs such as myriad genetics).
10 years earlier. The general recommendation is to get a colonoscopy at an age 10 years younger than the youngest age of your first degree family member when they were diagnosed. For example, if your mother was diagnosed with colon cancer at age 48, you should have a colonoscopy at age 38. The frequency depends on what they find at that 1st colonoscopy. If you have fap or lynch syndrome in your family, earlier.
I don't have a family history of cancer but I was worried about whether I have colorectal cancer. So what are my chances of getting colorectal cancer?
Under age. 50, about 4/100, 000. After age 50, it goes up sharply. Unless you have ulcerative colitis, multiple polyps, or any condition that increases your chances, you don't need to have a conlonscopy until age 50.
Can young people get colorectal cancer? If there is no family history and if the person is under 30, should they be concerned about getting colorectal cancer?
Yes, but it is rare. Colon cancer is rare under age 40. It can occur in people with predisposing conditions like ulcerative colitis or familial polyposis. The vast majority of cases occur in people over 50. That is the age when screeing should start for most people. In short, colon cancer should be low on the list of concerns for someone in their 20s (unless they have the conditions I mention above).
In short, yes but. It is much less often than in folks over the age of 45. Young folks with colitis or a family history of colon polyps or cancer are at increased risk. If you are having symptoms related to your colon that are persistent, see a GI doctor or colorectal surgeon and let them decide if diagnostic testing is necessary.
By age 40 or sooner. Colonoscopic screening for cancer is recommended by age 50 and earlier if there is a family history. You should develop a relationship with a primary care provider long before you may need the services of a doctor so that s/he may advise you about other preventive and health maintenance matters.
Screening. You should start colonoscopy screening at age 40 or ten years before the earliest case in your family, whichever is earlier.
I am 22 and experiencing incomplete evacuation after a bowel movement and occasional flatulence. Can it be colorectal cancer-i have no family history?
See a GI doctor. The symptoms are not common for colorectal cancer but if it is a change, see a GI doctor.
Probably not. Colon cancer would not be the first diagnosis I would come up with those symptoms in a 22 year old. Best to see your friendly GI doctor to help with your symptoms.
