Colon Cancer | Early Warning Signs & Stages of Colon Cancer

Low-grade VS High-grade

Cancer is also classified on the basis of grades. The lower grade represents a less severe cancer, while a higher grade represents more advanced levels.

The cancer cells get rankings when they are observed under a microscope. The microscopic features of the tumor cells elaborate the differentiation of the cancer cell. If the tumor looks less differentiated, a lower grade is given. The higher grades are given to the cells which are highly differentiated from the parent tissue and looks more abnormal. The higher the differentiation between cells, the higher will be their grade and malignancy.


There are numerous causes of colon cancer. It includes smoking, drinking alcohol in excess, diabetes, obesity, aging, hereditary, and less active lifestyle etc. Usually, colon cancer is diagnosed in people at the age of 50. But those with a family history of colorectal cancer can develop this disease at an early stage. There are a number of screening tests to detect colon cancer at initial stages. If diagnosed earlier and prompt treatment is given during the stage 1 or stage 2, the chances of full recovery are brighter. However, if the disease progressed to more advanced stages, it is very difficult to control the rapid spread of cancer.
