Colorectal cancer Treatment
Colorectal cancer

Patients diagnosed with colorectal cancer are mostly males aged about 50-75. Most colorectal cancers occur when a tiny polyp, often benign, undergoes gradual canceration over a course of 10 years or more. Generally, colorectal cancers are cancerous malignant tumors developed from benign tumors.

Surgical excision
This is the most common therapy. The colon is surgically removed alongside with neighboring lymphoid tissues. However, to facilitate defecation of patients in future, one end of the intestine must be connected to an artificial stoma outside the abdominal cavity. Its side effects include frequent defecation, frequent abdominal distension, etc.
It uses high-energy radiant rays to kill cancer cells or inhibit the proliferation of cancer cells, and reduce damage to normal cells. However, its side effects include diarrhea, skin inflammation, intestinal tract or bladder bleeding, impaired bone marrow functions, etc.
It destroys the self-replication of cancer cells by drugs so as to stop the proliferation of tumors. This therapy is particularly suitable for patients with metastatic colorectal cancer, contributing to alleviating their symptoms and stabilizing their conditions. However, its side effects include weakened immunity, fatigue, nausea, diarrhea, mouth pain, hair loss, redness and swelling on hands and feet, etc.
Targeted therapy
It attacks and kills specific cancer cells without causing damage to normal cells. For example, an angiogenesis inhibitor can cut off the blood supply of tumor cells to block the nutrients that allow them to proliferate, "starving" the cancer cells to death. However, its side effects include hypertension, fatigue, diarrhea, and even internal bleeding and gastrointestinal perforation.
