Currently, clinically for colon cancer, there are mainly the following treatments:
Surgery can be applied to almost all stages of colon cancer patients. Depending on the patient's condition, the surgical methods selected are also different. In the early stage, local excision is the main method, and the lesions are removed through surgery. If the tumor grows relatively large and the doctor suspects that there are cancer cells distributed around it, a colectomy and anastomosis is usually performed, which is to remove part of the patient's colon, including the lesion and some normal tissue, and then anastomose the severed colon.
2. Chemotherapy and radiotherapy
Surgery can only remove visible lesions, but cancer cells may also lurk in normal tissues, so 40% to 50% of patients may eventually experience recurrence and metastasis, which is also a major factor threatening the patient's later survival. Chemotherapy plays an important role in patients with high-risk factors for recurrence or metastasis. Adjuvant chemotherapy can reduce the possibility of recurrence and metastasis.
However, chemotherapy not only kills cancer cells in the body, but also affects normal cells. Therefore, patients may experience multiple symptoms such as weakness, leukopenia, and loss of appetite during chemotherapy. If the patient's condition is relatively poor, he or she may not be able to withstand the various discomforts caused by chemotherapy, and may even aggravate the condition. Therefore, chemotherapy also needs to be selected according to the patient's own situation.
Radiotherapy is actually radioactive therapy, which is generally used for the treatment of late-stage colon cancer and metastasis. At this time, the patient has lost the best opportunity for surgery. The use of radiotherapy can carefully remove the metastases and eliminate excess cancer cells in the body, thereby prolonging the patient's life.
3. Immune cell therapy
This is a commonly used and relatively mature anti-cancer method in recent years. After the lesion removal surgery, in order to improve the activity of the body's immune system, and when the body allows it, immune cell therapy can be performed. This therapy mainly involves: after immune cells are cultivated, activated and trained, they are injected into the patient's body.
By obtaining the antigen information of the cancer cells, the immune cells can launch an attack on the cancer cells as soon as they find them. By completely destroying it, it can effectively inhibit the metastasis of cancer cells and control the further development of lesions.
The above are the methods commonly used in clinical treatment of colon cancer. For patients with colon cancer, only early treatment can improve the prognosis. And if you want to detect colon cancer as early as possible, the best way is to have a "physical examination"! Especially patients with a family history of colon cancer, adenomatous disease, and chronic colitis should not ignore physical examination.
