What are the treatments for rectal tumors

Treatments for rectal tumors include surgery, which is a treatment for early-stage rectal cancer because the effect is more obvious. Chemotherapy is an auxiliary treatment method after rectal cancer surgery, but it has great side effects.

1. Surgical treatment of rectal cancer: It is the preferred treatment method for early rectal cancer and has obvious therapeutic effects. Surgical treatment of rectal cancer can also be used for patients in the middle and late stages who have no contraindications to surgery. It can remove the metastatic lesions of rectal cancer, but the effect is not ideal. Surgical treatment of rectal cancer, whether in the early or advanced stages, is prone to recurrence and metastasis. Combining biological immunotherapy after surgery and using one's own immune cells for anti-cancer treatment can effectively consolidate the surgical results and effectively prevent cancer metastasis and recurrence.

2. Chemotherapy for rectal cancer: mostly used as adjuvant therapy before and after rectal cancer surgery. When used before rectal cancer surgery, it cannot improve the patient's survival rate, but it can shrink the tumor to a certain extent, which is beneficial for surgical resection and preservation of sphincter function and can reduce the chance of tumor spread during and after surgery. Many studies have shown that the use of adequate combined chemotherapy after surgery can improve the patient's survival rate. However, since most patients are weak after surgery and find it difficult to tolerate the toxic side effects of chemotherapy, biological immunotherapy is often combined clinically to reduce its toxic side effects.

3. Radiotherapy for rectal cancer: Radiotherapy for rectal cancer must be used with caution. Not only its efficacy on the cancer lesions should be considered, but also its damage to the adjacent organs around the rectum. In clinical practice, it is generally only used as an adjuvant treatment for rectal cancer surgery. It has certain contraindications and should be used with caution in patients with poor physical constitution. In clinical practice, it is often combined with biological immunotherapy to reduce its toxic side effects.
