Unlike other cancers, the symptoms of colorectal cancer can be difficult to detect early. However, there are certain symptoms that you should be aware of, including pain and a yellowing of the skin or eyes. The disease is most successful when detected early, but it may not appear until it is quite advanced. It may also be asymptomatic for years, or not at all. Here are the symptoms of colorectal cancer and how to recognize them.

Early stage: If the cancer is only inside the inner layer of the colon or rectum, it is called a carcinoma in situ. It has not spread beyond this layer and is easily treated. Stage 1: The cancer has spread to the colon’s wall but hasn’t spread to nearby lymph nodes. Stage 3: The cancer has spread to nearby organs and lymph nodes, but is still considered a localized tumor.

Stage 0: Early stage cancers may have no visible signs. Often, cancer cells are detected in stage 0 lesions, known as “carcinoma in situ.” These lesions are not cancerous, and removing them may be all that is required. In other cases, a diagnosis of colorectal cancer will help determine which treatment options are right for you. Fortunately, there are several options for treating this condition.

Early stage colorectal cancer can occur in people younger than the recommended age for colon cancer screening. It may also develop between screenings, so it is important to have regular checkups to catch it in its early stages. If you experience any of these symptoms, see your doctor immediately to be safe. He will assess your symptoms, including frequency and duration, and then determine if you have colorectal cancer.

The disease usually starts in the colon or rectum, which are parts of your digestive tract. The most common form of colorectal cancer is adenocarcinoma. It begins in the colon lining and spreads to other parts of the body. Unlike other types of cancer, this disease is more likely to affect African-Americans than other races. A person with inflammatory bowel disease is more likely to develop colorectal cancer in the future.

If you suspect you have colorectal cancer, your doctor will perform a biopsy in order to diagnose the disease. A biopsy will be needed to determine the extent of the tumor. The doctor will also examine the tissue under a microscope to determine whether it has cancer cells or not. If the tissue has cancer cells, genetic tests may be performed to confirm its diagnosis. Other lab tests may be performed to classify the type of cancer.

Other symptoms of colorectal cancer may be rectal bleeding. A bright red or dark red blood in the stool may be an indicator of colon cancer. Occasionally, this symptom may be caused by a hemorrhoid or a fissure. However, if the blood is excessively large, it may be indicative of colorectal cancer. In addition, stool consistency can indicate a number of internal problems. A small, hard stool may indicate constipation, while any other changes in stool should be evaluated by a physician.
