Colorectal cancer can be treated with chemotherapy drugs

Colorectal cancer can be treated with chemotherapy, and many people generally choose this method. So what are the treatments for colorectal cancer? This is a question that people often ask. Let the experts answer for us what treatments there are for colorectal cancer .

The treatment of colorectal cancer can be mainly manifested in the following aspects:

1. Surgical treatment: The only radical cure for colorectal cancer is early removal of the tumor. If cancer metastasis is found during exploration, but the diseased intestinal curve is still free, the colorectal cancer should be removed in principle to avoid intestinal obstruction in the future; on the other hand, the tumor is often eroded, bleeding or accompanied by secondary infection, and resection can improve the general condition. For patients with extensive cancer metastasis, if the diseased intestinal segment can no longer be removed, palliative surgery such as fistula or shortcut should be performed, which is the treatment of colorectal cancer.

2. Radiotherapy: The efficacy is still unsatisfactory. Some people believe that: ① Preoperative radiotherapy can shrink the tumor, increase the resection rate, reduce regional lymph node metastasis, intraoperative cancer cell spread and local recurrence; ② Postoperative radiotherapy: For cases that require radical surgery, such as the tumor has penetrated the intestinal wall, invaded local lymph nodes, lymphatic vessels and blood vessels, or there are residual tumors after surgery but there is no distant metastasis, postoperative radiotherapy is appropriate; ③ Simple radiotherapy: For cases of advanced rectal cancer, small doses of radiotherapy can sometimes have a temporary hemostatic and analgesic effect. This is the treatment of colorectal cancer.

3. Chemotherapy: After radical resection of colorectal cancer, about 50% of cases still have recurrence and metastasis, mainly because the hidden metastatic lesions were not found before surgery or the lesions were not completely removed during surgery. Therefore, before laparotomy, intra-intestinal chemotherapy for tumors or preoperative enema for rectal cancer can prevent the spread of cancer cells, kill and eliminate cancer cells. Continuing chemotherapy after surgery may increase the 5-year survival rate after radical resection, which is the treatment of colorectal cancer.

4. Cryotherapy: Cryotherapy uses liquid nitrogen as a refrigerant. After fully exposing the tumor through an anoscope, cryotherapy uses shell-shaped cryotherapy heads of varying sizes to contact the tumor tissue, which can effectively kill and destroy the tumor tissue. When patients in the middle and late stages cannot undergo surgery, it can be used as appropriate to reduce the patient's pain and avoid artificial anus. It can be combined with chemotherapy to achieve satisfactory results. This is the treatment of colorectal cancer.

The above is the explanation given by experts on the treatment of colorectal cancer. I hope it can help you answer your questions. Experts remind everyone that if you suffer from any disease in your daily life, you must not delay treatment. This is very dangerous. Some diseases will worsen or cause other diseases.
