Learn what each stage of colorectal cancer means, from Stage 0 (usually a polyp)
to Stage IV (spread to distant organs), and the treatment options available for
each stage, including surgery, chemotherapy and radiation.
Title: Stages of tumor growth
Stage 0
The condition is precancerous (usually found in a polyp). Removal of the polyp (polypectomy)
is the usual treatment.
Stage I
Cancer is confined and has not spread to neighboring tissue. Your treatment is most
likely surgery.
Stage II
Cancer has spread beyond the original (primary) site, but there is no lymph node
involvement. Treatment options are usually surgery and sometimes chemotherapy.
Stage III
Cancer has spread beyond the original (primary) site to nearby lymph nodes but not
to other parts of the body. Your treatment options are usually surgery, chemotherapy,
and sometimes radiation.
Stage IV
Cancer has spread to distant organs. Your treatment options may include chemotherapy,
surgery, and radiation.
