Cancer surgery is currently one of the most common methods for cancer, through which tumor tissue can be removed, reducing the patient's pain and prolonging survival. However, in some cases, cancer cells will metastasize and spread after surgery, which brings new challenges to patients. To better understand this question, here are four reasons why we need to take it seriously.
First, surgical trauma may stimulate the metastasis and spread of cancer cells. Cancer cells can be mechanically damaged during surgery, which causes changes inside the cells that make it easier to break away from the primary tumor and enter the bloodstream or lymphatic system. In addition, the procedure may cause an inflammatory response, releasing a range of cytokines and chemicals that may promote the migration and invasion of cancer cells.
Second, immunosuppression after surgery may provide favorable conditions for the metastasis and spread of cancer cells. Surgical trauma and the use of *** substances may lead to the suppression of the immune system, which makes the body's immune monitoring and elimination of cancer cells decrease. In this way, cancer cells that were originally controlled by the immune system have a chance to escape immune surveillance and spread further to other sites.
Third, the tumor bed after surgery may become a "breeding ground" for cancer cells to metastasize. After surgical removal of the tumor, there may be remnants of cancer cells in the remaining tumor bed, which may have a greater ability to invade and metastasize. In addition, there may be a range of growth factors and cytokines present in the tumor bed after surgery, which may provide a favorable environment for cancer cells to grow and migrate.
Finally, the blood circulation and lymphatic system after surgery may become a conduit for cancer cells to metastasize. Abnormalities in the blood and lymphatic systems can occur during surgery, making it easier for cancer cells to enter these systems and spread to other parts of the body through the blood or lymph. In addition, there may be some abnormal vascular and lymphatic structures in the blood circulation and lymphatic system after surgery, which may provide better metastatic pathways for cancer cells.
In summary, the reasons for the metastasis and spread of cancer cells after cancer surgery can be attributed to many aspects such as surgical trauma, immunosuppression, tumor bed, and blood circulation lymphatic system. Understanding these causes can help us better prevent and control the metastasis and spread of cancer cells, and improve the effectiveness of surgery**. Therefore, we should take this issue seriously and strengthen the monitoring and care of patients after surgery to reduce the risk of cancer cells metastasizing and spreading and improve the quality of life of patients.
