Colorectal Cancer Stages
Determining the stage of the cancer
is a very important step; it helps your oncologist to determine the type of treatment to use to better fight the
disease. In addition, the cancer stage at the diagnosis plays a major role in your survival chance. In general,
colorectal cancer includes the following stages:
- carcinoma in situ – also known as stage 0, carcinoma in
situ indicates the genesis of the cancer; it is still in the inner layer of the colon or
- Stage I
– at stage I, the tumor has affected the mucosa of the colon or rectum, but has
not yet spread beyond the colorectal wall.
- Stage II
– the tumor has spread from the
colorectal mucous into the wall of the colon or rectum without reaching the nearby lymph
III – a stage 3 colorectal
cancer has affected the inner layer of the colorectal tissue, colorectal wall and the nearby lymph nodes;
however, the tumor has not affected distant parts of the body.
- Stage IV
– in this last stage, the cancer has
spread to other organs of your body, such as liver, lungs, or ovary.
- Recurrent – a cancer that has returned after treatment is
considered as a recurrent cancer. In general, recurrent colorectal cancers are more difficult to be
treated; your survival chance is lower. To prevent recurrent cancer, after treatment, it is important that
you respect your doctor’s appointments, adopt a healthy lifestyle and consume a healthy diet.
