The increased use of multimodal therapy for the treatment of Stage II and III disease continues. [ncbi.nlm.nih.gov]

This local treatment may be accompanied by systemic (whole-body) treatment such as chemotherapy. When cancer is more extensive and surgery is not possible, systemic therapy is the primary approach to treatment. [michaelsmission.org]

The potential benefits of receiving cancer treatment must be carefully balanced with the potential risks of receiving cancer treatment. The following is a general overview of the treatment of Stage I rectal cancer. [texasoncology.com]

These stages are a lot like those for colon cancer, but because the tumor is much lower in the large intestine, treatment options may vary. Surgery to remove the cancer is almost always the first treatment. [webmd.com]

When clinical trials show that a new treatment is better than the standard treatment, the new treatment may become the standard treatment. Patients may want to think about taking part in a clinical trial. [bowelcanceraustralia.org]

CAN RECTAL CANCER BE PREVENTED? Rectal cancer is preventable. Nearly all rectal cancer develops from rectal polyps, which are benign growths on the rectal wall. [fascrs.org]

The mucin, in turn, creates a barrier that may, in fact, prevent chemotherapy medications from effectively penetrating cancer cells. In short, the chemo may not be able to get where it needs to be. [verywellhealth.com]

Prevention If there is a family history of developing such cancer, one should get regular screening tests to protect themselves from the disease. Other prevention measures include: Quitting smoking. Limiting alcohol consumption. [medanta.org]
