There are several different types of colorectal cancer. A Stage 1 cancer has not spread beyond the colon’s wall and has not yet reached lymph nodes or distant organs. Stage 2 cancer has spread into one or more lymph nodes and has not yet metastasized. Stage 3 and 4 cancers have spread beyond the colon but have not yet metastasized to other parts of the body. Once it has spread beyond the colon, it may not return.

Some colorectal cancer symptoms are not immediately apparent. The initial symptoms of this disease are often mistaken for other conditions, including hemorrhoids, ulcerative colitis, and Crohn’s disease. Although colorectal cancer is rarely fatal, if you notice any of these symptoms, see your doctor for a consultation. If you notice a change in the color of your stool, make an appointment immediately.

The stage of the cancer will determine the type and severity of treatment that will be needed. Lower staged cancers are those that have not spread, and a stage III cancer has spread to lymph nodes. The higher the stage, the lower the chance of survival. If your cancer has spread, you may need chemotherapy to slow the spread of the cancer. However, you should be aware of the fact that it can spread to other organs.

Depending on the type of colorectal cancer, your symptoms may not appear until you reach stage 2 or stage 3. It is important to see your doctor regularly and undergo regular screenings. If you have a family history of colorectal cancer, it is recommended to go for regular screening tests. You should also be aware of any symptoms that may be associated with rectal or colon cancer.

Screening for colorectal cancer is essential to detect early polyps before they transform into cancer. Fortunately, the disease is curable when detected early. Screening has an excellent 5-year survival rate when diagnosed early. In fact, about 40 percent of people diagnosed with colorectal cancer are diagnosed in the early stage. And thanks to medical advances, screening has become more effective. It also has a lower incidence than ever.

While doctors cannot pinpoint the exact causes of colon cancer, certain factors seem to increase the risk of developing the disease. ACS notes that some genes may increase the chances of developing colorectal cancer. DNA changes can result in changes in certain genes in the body that help the cells stay alive and grow. These changes can either affect oncogenes or tumor suppressor genes. Some cancers can start as polyps in the colon, but some polyps are benign and can cause cancer.

However, colorectal cancer may not have any noticeable symptoms in the early stages. So it is important to know the symptoms of colorectal cancer as soon as possible. This is especially true if the cancer is in the early stages.
