Minimally invasive interventional medicine for tumors is a branch of surgical oncology, which also intersects with imaging, with a relatively short history of less than 30 years. Interventional treatment methods are characterized by small trauma, wide indications, reliable efficacy, low recurrence rate, low price, short operation time, fast recovery and repeated treatment. In terms of solid tumors, interventional treatment can be done for almost anything that can be treated by surgery, and even for many diseases that cannot be solved by surgery, interventional medicine can also do so. For liver cancer, radiotherapy and chemotherapy are generally effective, and surgery is almost the only option. Interventional therapy can cover almost all liver cancer patients with a wider range of indications than traditional surgery. Even for patients with advanced stage and those who can only be treated symptomatically by traditional surgical tasks, interventional therapy can reduce patients’ pain and can prolong their survival to a certain extent. For lung cancer, open-heart surgery is more traumatic due to the obstruction of the thoracic ribs, and interventional treatment is also a very good means.
