What Are the Early Warning Signs of Colon Cancer?
Colon cancer starts in the last portion of the
digestive tract, known as the colon. It usually occurs in older
adults but can occur at any age. Colon cancer, sometimes referred to as
colorectal cancer, is the third most common cancer in
both men and women in the United States, excluding skin cancers. Colon cancer
begins with small noncancerous cell clumps, known as polyps, in the colon. Some
polyps can become cancerous with time.
Polyps cause very few and unrecognizable symptoms, if at
all. Some of the symptoms and risk factors include:
·
Blood in the stool, persistent changes in bowel
consistency including constipation or diarrhea, fatigue or weakness, persistent
abdominal discomfort, inexplicable weight loss, and feeling like the bowel
doesn’t completely empty. Many of these symptoms will appear later and will
most likely be varied depending on the size of the cancer and where it is
located in the large intestine.
·
Generally, colon cancer occurs when healthy
cells experience DNA mutations. Its causes remain uncertain but there are
certain factors that predispose one to it. These include: older age, chronic
inflammatory intestinal conditions such as Crohn’s disease, personal or family
history of colon cancer, are African-American, sedentary lifestyle, a low-fiber
high-fat diet, smoking, alcohol consumption, diabetes, obesity, and radiation
therapy directed at the abdomen for the treatment of other cancers. Some gene
mutations passed down from family could put some at a higher risk of this
particular cancer. These syndromes include Lynch syndrome and familial
adenomatous polyposis (FAP).
