Colon Cancer Symptoms

The colon is part of the large intestine and the final part of the digestive system. It plays an important role in absorbing fluids, salts and other waste products from our body and preparing for its elimination.

Colon cancer also referred to as colorectal cancer mainly affects the large intestine and it usually starts with polyps in the walls of the large intestine varying in their size. According to the records, this cancer is the third most common cause of cancer-related death. This can be easily preventable and highly curable if detected in the early stages.

It begins as small clumps of cells formed inside the colon. Over time, these clumps become cancerous. There are several treatments that help to control colon cancer, such as radiation, drug treatment, chemotherapy, surgery, etc.

The exact cause of colorectal cancer is unknown. There are certain genetic causes, other histories of breast, uterine or ovarian cancer, lifestyle changes, age-related, etc.
