Quite rare; not zero. Colorectal cancers in young adults are most often due to a genetic problem like hnpcc (hereditary nonpolyposis colorectal cancer) or fap (familial polyposis coli). Cr cancers can also be seen in young adults with inflammatory bowel disease, although it is rare. Any young adult with symptoms that don't respond to treatment should seek further evaluation.
Extremely rare. This is quite uncommon, and usually only seen in people with an extensive family history of the disease, polyposis coli (a disease with thousands of polyps) or ulcerative colitis (an inflammatory disease of the colon known to [over many years] to cause cancer). You should be tested for genetic markers for colon cancer and other cancers to determine best treatment for you, and screening for family.
Rare. Rare, but certainly occurs.
Quite Rare. It is relatively rare. This raises the question of a genetic predisposition to this cancer (e.g. Lynch syndrome). The 25yo with the colon cancer should be seen by a genetics counseling team as well for possible genetic testing.
Pretty rare. Please check out www. Michaelsmission. Org it is a very informative website about colorectal cancer.
Full explanation please of why colon cancer is so rare in their 20s? But I read online of hundreds of stories people are telling about colon cancer in their 20s
Social phenomenon. As with most "news" what is talked about is the unique/unusual and tragic/dramatic stories. It doesn't surprise me that cancer in the young is blogged more than that of the usual/elderly. A generalization for most cancers can be made is that the older you are, the more vulnerable one is to a malignant transformation. Colon, breast are the most notorious. Familial risk increases with time.
It is rare. This normally is a disease of people over 50 and more typically in their 60's. Some theories about colon cancer suggest that a series of mutations must occur over time. This likely the reason that it is a rare disease in young patients. It can occur in the young as part of a genetic syndrome. Usually found in families. The typical rarely is news or of internet interest. The odd situation is.
Need exposure/time. Cancers like colon and lung cancer need time and exposure to promoting substances to develop. Lung cancer develops over years of exposure to smoking, even if a small amount of smoking puts one at risk for it. Colon cancer comes from years of a diet high in animal fat, etc. Exceptions are those with polyposis symdromes, etc. That make it almost certain that colon cancer ossurs at a younger age.
Mutations. There are many theories. One is that cancer is often the result of several mutations in cells that occur over time. It may take several of these mutations over time to cause cancer. Another is that certain cell growth control systems get inactivated over the years. This is call epigenetic change. Also over time more environmental exposures take their toll. Age allows more of these thing to happe.
5% From 2005-2009, the median age at diagnosis for cancer of the colon and rectum was 69 years of age. Approximately 0.1% were diagnosed under age 20; 1.1% between 20 and 34; 4.0% between 35 and 44; 13.4% between 45 and 54. You should see a genetician to see if there is familial cancer syndrome like hnpcc.
Curious: What are the chances of colon cancer in someone age 34, non smoker, rare drinker, no fam hx, healthy weight (BMI around 21 or 22)?
Low risk before 50. Colon Cancer and Age 90% of new cases and 95% of deaths from colon cancer occur in people 50 or older. However, colon cancer does not discriminate and can happen to men and women at any age. While rates for colon cancer in adults 50 and older have been declining, incidence rates in adults younger than 50 years has been increasing. Just launched! New pages with tons of information about young-onset colon cancer, who’s at highest risk and resources for you. Check them out! Colon Cancer and Ethnicity and Race Jews of Eastern European descent (Ashkenazi Jews) may have a higher rate of colon cancer. Partly because of disproportionate screening, African-American men and women have a higher risk of developing colon cancer and a lower survival rate (about 20% higher incidence rate and 45% higher mortality rate) compared to Caucasians, Asians, Hispanics and Native Americans. The risk of death is also increased for Native Americans and Alaskan Natives. Colon Cancer and Family History People with a first-degree relative (parent, sibling, or children) who has colon cancer are between two and three times the risk of developing the cancer than those without a family history.
Uncommon. Cancer of the colon is frequently seen in younger pts. When inflammatory bowel disease is present. The disease is related to inflammation not controlled by normal MicroBiome. Another cause is development of a field effect secondary to a carcinogen or virus. The virus probably polyoma which induces transformation. In past years certain meds contaminated by SV40 virus which can induce Ca.
22 yr old I am are colon cancer a rare sign of colon cancer? Its not listed as the signs of colon cancer im scared I may have it because of noappetite
Rarely. No appetite (anorexia) is a rare and late presentation of colon cancer. Your age is another reason you are unlikely to have colon cancer. Rectal bleeding, change in stools or abdominal pain/bloating are more common symptoms. Anorexia can indicate other problems so I recommend you see your doctor, especially if it is making you lose weight!
Go to your doctor. Please check out www. Michaelsmission. Org it is a very informative website about colorectal cancer.
How rare is colon cancer in a 28 year old female? My family has no history of the disease. I've recently been diagnosed with ibs.
Colon cancer. Colon cancer is rare is young people but can be see in association with diseases such as familial polyposis. Patients with ulcerative colitis or Crohn's disease involving the colon with longstanding colitis are at greater risk of developing colon or rectal cancer than the general population. Patients who develop IBD at a younger age may be at an increased risk when they are older.
