Most common colon cancer symptoms
When colon cancer is caught before it spreads to any other tissue, the survival rate is 91%.
Colorectal cancer is the third-most commonly diagnosed cancer and the third-leading cause of cancer death in men and women combined in the United States. The American Cancer Society estimates the risk of developing colorectal cancer at about 1 in 23 for men and 1 in 26 for women.
If cancer begins in the colon, which is the first four to five feet of the large intestine, it may be referred to as colon cancer. If the cancer begins in the rectum, which is the last several inches of the large intestine leading to the anus, it is called rectal cancer.
If caught early when only in the bowel, colorectal cancer is highly treatable and often curable.
Because early detection is key, rectal and colon cancer screening guidelines recommend that people of average risk begin screening at age 45. But if you have a family history or symptoms, you should talk with your health care provider about starting earlier.
Continue regular screening through 75. If you are over 75, talk with your doctor about whether screening is right for you.
Several factors can increase your rectal and colon cancer risk factors.
Having one or more of these risk factors does not guarantee that you will develop colon or rectal cancer.
Several screening tests are available for early detection of colon and rectal cancer. These tests can help identify precancerous polyps or detect cancer early, when it is more treatable.
This is considered the gold standard for colon cancer screening. During a colonoscopy, a long, flexible tube with a camera (colonoscope) is inserted into the rectum to examine the entire colon. It allows the doctor to visualize the colon and rectum, remove polyps and take tissue samples for analysis.
This procedure involves the insertion of a flexible, slender tube with a camera (sigmoidoscope) into the rectum and lower part of the colon. It allows visualization of the rectum and sigmoid colon but not the entire colon. A follow-up colonoscopy may be necessary if polyps or suspicious areas are found.
Stool-based tests look for problems after they happen, while a screening colonoscopy looks for anything that might cause a problem. Stool tests are only appropriate for those considered low risk for colorectal cancer. You will need a colonoscopy if the test returns positive.
Preparation begins the day and night before the procedure. Your doctor will also prescribe a colon cleanse beverage and anti-gas medication along with fasting. Cleansing the colon is essential for accurate screening.
The procedure takes about 30 minutes, and complications and risks are low.
First, you are sedated. Many people describe it as the best nap they have ever had. Next, the doctor will perform the colonoscopy. Because you will be sedated, you will need someone to go with you to drive home.
You will wake up in the recovery room. After a short observation and recovery from the sedative, you can eat and go about your day.
The most appropriate screening test depends on various factors, including individual risk, personal preferences and your primary care provider’s recommendation.
Talk to your primary care provider about your risk factors and when to be screened for colorectal cancer.
