Why is the sigmoid colon susceptible to cancer?

Background: Cancer of the sigmoid colon is especially sensitive to environmental factors such as food. The authors have conducted a series of studies with food as the external environmental factor and intestinal microflora as the internal environment factor in relation to sigmoid colon carcinogenesis.

What part of the colon is most likely to develop cancer?

The sigmoid colon is the most common site for cancer of the colon. Rectal carcinoma is the most common cancer of the lower gastrointestinal tract.

Can a 25 year old have colon cancer?

Colon cancer is rare in individuals under age 25. Prevalence of the disease in patients under age 20 is 0.2 percent. While the Surveillance, Epidemiology and End Results Program (SEER) estimates more than 145,000 new cases of colon cancer for 2019, only about 290 cases are expected in children and young adult people.

Is colon cancer one of the worst?

Colon cancer is the second most deadly form of cancer after lung cancer. But it’s one of the easiest diseases to detect, and in its earliest stages, it’s also one of the most curable. If you’ve been diagnosed with colon cancer, or if you’re at risk for the disease, it’s time to learn everything you can.

Can a 23 year old get colon cancer?

Why is colon cancer more common in males?

Conclusions. As there are minimal sex differences in the data from routes to diagnosis to survival, the higher mortality of colorectal cancer in men appears to be a result of exogenous and/or endogenous factors pre-diagnosis that lead to higher incidence rates.

Is colon cancer more common in ethnicity?

Your racial and ethnic background African Americans have the highest colorectal cancer incidence and mortality rates of all racial groups in the US. Jews of Eastern European descent (Ashkenazi Jews) have one of the highest colorectal cancer risks of any ethnic group in the world.

Who is likely to get colon cancer?

Age. 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.

Which race gets the most colon cancer?

Colorectal cancer also disproportionately affects the Black community, where the rates are the highest of any racial/ethnic group in the US. African Americans are about 20% more likely to get colorectal cancer and about 40% more likely to die from it than most other groups.

What are the risk factors for HNPCC colon cancer?

Colon cancers in HNPCC are characterized by early age of onset and predominant involvement in the right (or ascending) side (or part) of the colon. Cancer risk is also increased for endometrial, ovary, stomach, small bowel, the hepatobiliary system, and the urinary system.

What makes hereditary non polyposis colorectal cancer so common?

Hereditary non-polyposis colorectal cancer (HNPCC), or Lynch syndrome, is one of the more common familial cancer syndromes, affecting one in 1000 individuals. The molecular basis for HNPCC is a defect in a DNA mismatch repair gene, usually a germline mutation in hMLH1 or hMSH2.

Which is the most common inherited cause of colon cancer?

Only a small percentage of colon cancers are linked to inherited genes. The most common inherited syndromes that increase colon cancer risk are familial adenomatous polyposis (FAP) and Lynch syndrome, which is also known as hereditary nonpolyposis colorectal cancer (HNPCC).

How many relatives have been diagnosed with HNPCC?

At least three relatives have colorectal or other HNPCC-related cancers, with one person being a first-degree relative (parent, child, or sibling) of the other two; At least one person received a diagnosis of colorectal cancer before age 50;

How is hereditary non polyposis colorectal cancer ( HNPCC ) diagnosed?

Hereditary Non-polyposis Colorectal Cancer (HNPCC) Abnormalities in some of the genes in colon cells that control cell growth and death can cause colorectal cancer. Hereditary Non-polyposis Colorectal Cancer (HNPCC), which affects nearly 5 percent of colorectal cancer patients, is characterized by a mutation in an important gene,…

Colon cancers in HNPCC are characterized by early age of onset and predominant involvement in the right (or ascending) side (or part) of the colon. Cancer risk is also increased for endometrial, ovary, stomach, small bowel, the hepatobiliary system, and the urinary system.

Which is an inherited gene that causes colon cancer?

Inherited gene mutations that increase the risk of colon cancer. Hereditary nonpolyposis colorectal cancer (HNPCC). HNPCC, also called Lynch syndrome, increases the risk of colon cancer and other cancers. People with HNPCC tend to develop colon cancer before age 50. Familial adenomatous polyposis (FAP).
