"How long can someone survive with bowel cancer that has metastasized to the peritoneum?"

It is generally inaccurate to predict how long a patient with colon cancer that has metastasized to the peritoneum can live. The presence of peritoneal metastasis in colon cancer indicates an advanced stage of the cancer, possibly mid-stage or late-stage, resulting in a relatively shorter survival time. With active cooperation with medical treatment, the 5-year survival rate may be around 50%; however, without such cooperation, the 5-year survival rate may drop to 20%, emphasizing the importance of prompt and appropriate medical intervention.

Colon cancer refers to the development of cancerous cells in the tissue of the intestinal mucosa. In its early stages, it may not exhibit metastasis or spread of these cells. The occurrence of peritoneal metastasis signifies disease progression, indicating that the cancerous cells have already undergone distant metastasis. Failure to treat this condition promptly can jeopardize the patient's health.

It is crucial for individuals with colon cancer to seek early detection and treatment without delay. Treatment options may include resection via colonoscopy, transanal endoscopic microsurgery (TEM), open surgery, and postoperative approaches such as radiofrequency ablation, cryotherapy, and immunotherapy to inhibit further metastasis and proliferation of cancerous cells.
