Colorectal Cancer
What is Colorectal Cancer ?
Colorectal cancer is a type of uncontrolled growth of abnormal cells that can develop in the colon, rectum or both. Together the colon and rectum make up the large intestine (large bowel). It carries the remnants of digested food from the small intestine and eliminates them as waste through the anus.
What are the Symptoms of Colorectal Cancer?
Precancerous polyps and early colorectal cancer generally don't cause symptoms. More advanced cancer can cause any of the following symptoms.
- A change in bowel habits
- Diarrhea or constipation
- Blood in the stool (bright red, black or very dark)
- Narrowed stools (about the thickness of a pencil)
- Frequent gas pains
- A feeling that the bowel does not empty completely
- Weight loss without dieting
- Continuing fatigue
How it can be diagnosis ?
Colorectal cancer usually is diagnosed by a sigmoidoscopy or colonoscopy. In these tests, a flexible viewing tube is inserted into your rectum and colon to look for polyps or cancerous masses.
You also may have a test called a barium enema. In this test, a fluid containing a substance called barium is pumped into your rectum before X-rays are taken. The barium helps abnormalities show up on the X-rays. These tests provide information about the size and location of the cancer.
Sometimes, if the cancer has spread outside the colon or rectum, you may need a biopsy of that area. In a biopsy, a small piece of tissue is removed and examined in a laboratory.
