Several main non-surgical treatments for colon cancer

For patients with colon cancer, in addition to surgical treatment, they can also choose non-surgical treatment. Patients agree that they can get good results in treating colon cancer , and the harm caused will be relatively small, which is beneficial to patients. What are the main non-surgical treatments for colon cancer? The following will tell you about the main non-surgical treatments for colon cancer.

In general, the main non-surgical treatments for colon cancer are:

Biological therapy: Immunotherapy and gene therapy are both biological therapies. Currently, immunotherapy is the most commonly used method for treating colon cancer in clinical practice. It mainly mobilizes the body's natural anti-cancer ability and restores the balance of the body's internal environment, which is equivalent to "strengthening the body's health and harmonizing yin and yang" in traditional Chinese medicine. Biological therapy can prevent tumor recurrence and metastasis, improve the efficacy of radiotherapy and chemotherapy, and reduce the toxic side effects of radiotherapy and chemotherapy.

Targeted therapy: The so-called molecular targeted therapy is to design corresponding therapeutic drugs at the cellular molecular level, targeting the already identified carcinogenic sites (the site can be a protein molecule inside the tumor cell or a gene fragment). When the drug enters the body, it will specifically select the carcinogenic sites to combine and act, causing the tumor cells to die specifically without affecting the normal tissue cells around the tumor. It is also the main method for treating colon cancer.

Chemotherapy: As colon cancer grows and develops, it gradually metastasizes to distant sites. Three-quarters of patients already have metastases at the time of diagnosis. Of those who can undergo radical surgery, half of them eventually develop distant metastases. Therefore, chemotherapy after radical surgery, i.e. adjuvant chemotherapy, is an important component of the treatment of colon cancer. The mechanism of adjuvant chemotherapy is to use chemotherapy to control and eliminate residual lesions in the body after radical surgery. After surgery, the body's tumor load is reduced, and the proliferation of distant micro-metastases increases its sensitivity to chemotherapy. Early chemotherapy after surgery can achieve the greatest goal of eliminating the tumor.

Radiotherapy: For patients with unresectable tumors or distant metastatic lesions, local radiotherapy is also a good method for treating colon cancer. It can shrink tumors and improve patients' symptoms. It is often used in combination with other treatment options. Currently, the most studied and effective treatment is the combined treatment of surgery and radiotherapy, including preoperative radiotherapy, intraoperative radiotherapy, postoperative radiotherapy, and "sandwich" radiotherapy.

The above are the main non-surgical methods for treating colon cancer. I believe everyone should have a certain understanding of this. If you have more questions about the treatment of colon cancer, you can consult our online experts, who will answer them in detail and seriously.
