I have a similar post sometime ago when an aunt of mine died of it. Then Cory Aquino died of it, and now, another relative and the mother of one of my staff are suffering from it.
Colorectal cancer is the third most common cancer in the United States. And it occurs most often in people older than 50. This type of cancer happens when cells that are not normal grow in your colon or rectum. These cells grow together and form tumors.
When it is found early, it is easily treated and often cured. But because it usually is not found early, it is one of the leading causes of cancer deaths worldwide. Screening tests can prevent this cancer, but only a few of us undergo screening. According to the American Cancer Society, if everyone were tested, tens of thousands of lives could be saved each year.
What causes colorectal cancer?
Most cases begin as polyps , which are small growths inside the colon or rectum. Colon polyps are very common, and most of them do not turn into cancer. But doctors cannot tell ahead of time which polyps will turn into cancer. This is why people older than 50 need regular tests to find out if they have any polyps and then have them removed. And some people who are younger than 50 need regular tests if their medical history puts them at increased risk for colorectal cancer or have signs and symptoms that can be suggestive of it.
What are the signs and symptoms?
Colorectal cancer usually does not cause symptoms until after it has begun to spread. See your doctor if you have any of these symptoms:
§ Pain in your belly
§ Blood in your stool or very dark stools
§ A change in your bowel habits, such as more frequent stools or a feeling that your bowels are not emptying completely
How is colorectal cancer diagnosed?
If your doctor thinks that you may have this cancer, you will need a test, called a colonoscopy , that lets the doctor see the inside of your entire colon and rectum. During this test, your doctor will remove polyps or take tissue samples from any areas that don't look normal. The tissue will be looked at under a microscope to see if it contains cancer.
Sometimes other tests, such as a barium enema or a sigmoidoscopy, are used to diagnose colorectal cancer.
How is it treated?
Surgery is almost always used to treat colon and rectal cancer. The cancer is easily removed and often cured when it is found early.
If the cancer has spread into the wall of the colon or farther, you may also need radiation or chemotherapy. These treatments have side effects, but most people can manage the side effects with medicines or home care.
Learning that you have cancer can be upsetting. It may help to talk with your doctor or with other people who have had cancer. Your local American Cancer Society chapter can help you find a support group.
How can you screen for colorectal cancer?
Screening tests can prevent many cases of colon and rectal cancer. They look for a certain disease or condition before any symptoms appear. Regular screening is advised for most people age 50 and older. If you have a family history of this cancer, you may need to begin screening earlier than that.
These are the most common screening tests:
§ Stool tests that check for signs of cancer:
§ Fecal occult blood test (FOBT).
§ Barium enema. A liquid with barium is put into your rectum and colon. The white liquid outlines the inside of the colon so that it can be more clearly seen on an X-ray.
§ Sigmoidoscopy. A doctor puts a flexible viewing tube into your rectum and into the first part of your colon. This lets the doctor see the lower portion of the intestine, which is where most colon cancers grow. Doctors can remove polyps during this test also.
§ Colonoscopy. A doctor puts a long, flexible viewing tube into your rectum and colon. The tube is usually linked to a video monitor similar to a TV screen. With this test, the doctor can see the entire large intestine.
§ Computed tomographic colonography (CTC). This test is also called a virtual colonoscopy. A computer and X-rays make a detailed picture of the colon to help the doctor look for polyps.
