The treatment of rectal cancer is what patients have always been pursuing, so what are the main methods of treating rectal cancer? This question has been raised by many people. Now, experts will introduce us to the treatment of rectal cancer . I hope that reading this article will be helpful to you.

The treatment of rectal cancer mainly includes the following:

1. Removing the tumor in the early stage of rectal cancer is a common treatment method for rectal cancer. The progression of rectal cancer is that tumor cells invade the mucosal layer, muscle layer and then the outer cortex of the large intestine. In the early stage of rectal cancer, since tumor cells only invade the mucosal layer, surgical resection can achieve a good therapeutic effect on rectal cancer. In the late stage, the lesions metastasize and turn into systemic diseases. The overall quality of patients is poor, and most of them can no longer tolerate the trauma caused by surgical resection. Moreover, it is not easy to completely remove the cancer by surgery. Therefore, the treatment of rectal cancer after its spread and metastasis cannot be treated by surgery alone.

2. Radiotherapy and chemotherapy are also common treatments for rectal cancer. Radiotherapy and chemotherapy are treatments that use various rays of different energies to irradiate the tumor to inhibit and kill cancer cells. Radiotherapy can be used alone or in combination with surgery, chemotherapy, etc. as part of comprehensive treatment to improve the cure rate of cancer. A period of radiotherapy before surgery can reduce the size of the tumor, so that patients who were originally unable to undergo surgery can have the opportunity to undergo surgery. For advanced cancer, palliative radiotherapy can be used to relieve compression and relieve pain. Radiotherapy and chemotherapy can reduce the tumor cell load locally or systemically, and the effect is fast, but it cannot eradicate tumor cells, is prone to metastasis and recurrence, has large systemic toxic side effects, and causes damage to the human immune function.
