What are the causes of recurrence after lung cancer surgery

summary

My uncle was found suffering from lung cancer during the physical examination some time ago. Recently, he had a resection operation. It is estimated that the method is not thorough, and there is a recurrence after the operation. Let me talk about the reasons for the recurrence after the operation.

What are the causes of recurrence after lung cancer surgery

First, the constitution of cancer has not changed. The reason why cancer patients suffer from cancer is that the body environment has a "cancerous constitution". Surgery, radiotherapy and chemotherapy kill cancer cells. However, the regulatory mechanism of cell differentiation in patients' body has not changed, and the living environment of cancer cells has not changed. Therefore, new cancer cells will continue to emerge, and cancer will relapse and metastasize.

Second, the treatment is not thorough. The tumor cells can be resected by surgery. Radiotherapy and chemotherapy can kill all or part of the adult cancer cells, but not the young cancer cells. When the patient's immune function is low, once the young cancer cells wake up from dormancy, fission and mutation quickly, new adult cancer cells will be formed, which is the fundamental reason for cancer metastasis and recurrence.

Third: low immunity. The cells in normal human body are metabolized day and night. In the new cells formed every day, about millions of cells will have gene mutation. If a few mutant cells are not restricted by the immune system, they will further malignant transformation and form tumor cells. Under normal circumstances, the body's immune system is always monitoring and eliminating these mutated and malignant cells or cancer cells in time. Once abnormal conditions are found, a large number of immune cells will be mobilized to wipe out "alien molecules", making it difficult to form a climate.

matters needing attention

The treatment of lung cancer is very difficult. Cancer is easy to relapse. As for the reasons, there are many aspects. For example, incomplete treatment leads to relapse. In addition, patients with lung cancer have low immunity.
