Kidney cancer is a common malignant tumor of the genitourinary system, which can be surgically removed if detected early. However, kidney cancer is usually hidden and difficult to detect, and most patients have lost the chance of surgical resection when they are diagnosed. Many patients will choose systemic chemotherapy or give up the treatment, in fact, interventional therapy can be adopted in this case. What is interventional therapy for kidney cancer? Under the guidance of imaging equipment, the interventional surgeon will thread a very tiny catheter from the thigh to the blood supply vessel of kidney cancer, and then tumor-killing drugs can be injected into the kidney cancer cells through the catheter to kill the cancer cells directly. Depending on the situation, the blood supply artery of kidney cancer can be blocked so that the kidney cancer cells are deprived of blood nutrition, which is simply called “starving the cancer cells”. Interventional treatment of kidney cancer is suitable for patients who cannot undergo surgical treatment. Its advantages are: 1. Less invasive: it is only a small puncture wound on the thigh, which can be slightly bandaged after surgery; 2. 3, good effect: while killing kidney cancer cells, it can also block the blood supply vessels of kidney cancer cells, i.e. nutrient channels, which enhances the therapeutic effect. In the treatment of kidney cancer, with the continuous development and perfection of interventional therapy technology, interventional therapy has become the third major clinical treatment system alongside with internal medicine and surgery, and interventional therapy for kidney cancer enables patients to achieve survival with tumor.
