Late-stage rectal cancer is primarily due to the metastasis and proliferation of cancer cells. At this stage, surgery alone cannot completely eliminate cancer cells, so chemotherapy is necessary. Chemotherapy has certain effects clinically, especially in patients who are sensitive to chemotherapy drugs, where the effects are more pronounced. This can control the spread of cancer cells in multiple locations and can, to some extent, improve patient survival rates. For patients, it is important to maintain good health, enhance their immune system, consume foods rich in high-quality proteins, and engage in appropriate exercise. Moreover, maintaining a positive mindset is beneficial for extending life. Additionally, patients can integrate traditional Chinese medicine and acupuncture as complementary therapies, which can also potentially improve postoperative survival rates.
