Simple, safe, effective, minimally invasive and with few complications. To a certain extent, interventional therapy = surgery without incision. The advantages of interventional therapy over traditional surgery are: 1. It requires no incision and generally only local anesthesia rather than general anesthesia, thus reducing the risk. 2. 2. Less damage, faster recovery, better results, less interference with the body, and protection of normal organs to the greatest extent. 3. For malignant tumors for which there is no curative method, interventional treatment can confine the drugs to the lesion as much as possible, while reducing the side effects on the body and other organs. Because of these advantages, many interventional treatments have become one of the most important treatment methods for certain diseases (e.g. liver cancer, lung cancer, lumbar disc herniation, aneurysm, vascular malformation, uterine fibroids, etc.), even replacing or eliminating the original surgical procedures.
