Is colon cancer genetically inherited?
Approximately 5 to 10 percent of colon cancer is hereditary. The major hereditary colon cancer syndromes are Lynch syndrome (previously known as Hereditary Non-Polyposis Colorectal Cancer or HNPCC) and Familial Adenomatous Polyposis (FAP). Other genes have also been implicated in hereditary colon cancer risk.
What are the chances of getting colon cancer if it runs in your family?
What Are the Chances of Getting Colon Cancer if It Runs in Your Family? Most people who develop colon cancer do not have a known family history of the condition. However, in approximately one out of every three cases, at least one family member is known to have had colon cancer as well.
Will I get colon cancer if my father had it?
If you have familial risk, a single first degree family member (parent or sibling) with colon or endometrial cancer under age 50, your lifetime risk increases to 10-20%. Family history is an important indicator not only because of shared genes, but similar lifestyles too.
When should you get a colonoscopy if colon cancer runs in your family?
Individuals with a family history of one or more first-degree relatives (sibling, parent or child) with sporadic colorectal cancer, regardless of age, should undergo colonoscopy beginning at age 40 years or ten years younger than the age of the affected relative at time of diagnosis, whichever is earlier.

Who gets colon cancer the most?
The risk of colorectal cancer increases as people get older. Colorectal cancer can occur in young adults and teenagers, but the majority of colorectal cancers occur in people older than 50. For colon cancer, the average age at the time of diagnosis for men is 68 and for women is 72.
How long does it take for colon cancer to get to stage 4?
Colon cancer, or cancer that begins in the lower part of the digestive tract, usually forms from a collection of benign (noncancerous) cells called an adenomatous polyp. Most of these polyps will not become malignant (cancerous), but some can slowly turn into cancer over the course of about 10-15 years.
What are the odds of getting colon cancer?
Overall, the lifetime risk of developing colorectal cancer is: about 1 in 23 (4.3%) for men and 1 in 25 (4.0%) for women. A number of other factors (described in Colorectal Cancer Risk Factors) can also affect your risk for developing colorectal cancer.
What is a strong family history of colon cancer?
A family history of colorectal cancer or adenomatous polyps
Still, as many as 1 in 3 people who develop colorectal cancer have other family members who have had it. People with a history of colorectal cancer in a first-degree relative (parent, sibling, or child) are at increased risk.
What type of food causes colon cancer?
Just like processed meats, processed grains can also increase your risk of colon cancer. Refined grains in white bread and other white flour foods can increase blood sugar levels, which lead to insulin resistance. This can raise your risk of colon cancer—as well as other cancers like kidney cancer.
