Tumors are undoubtedly very harmful to human body, especially malignant tumors, which have the characteristics of easy to spread, rapid development of disease and high death rate. Nowadays, because of the development of technology, there are many good treatment methods, especially the minimally invasive interventional therapy, which gives patients more chances to recover. Many people think that malignant tumor is an incurable disease and once suffering from this disease, it is a death sentence. No, the answer is in the negative. Minimally invasive interventional therapy is a kind of minimally invasive treatment by applying modern high-tech means, that is, under the guidance of medical imaging equipment, special catheters, guidewires and other precision instruments are introduced into human body to diagnose and locally treat lesions in the body. Interventional therapy has been developed to involve almost every organ of the human body. It does not require an incision, but only a small opening less than the size of a grain of rice, and a thin tube can be inserted into a blood vessel to treat many diseases. Minimally invasive interventional therapy has less damage, fewer side effects and high efficacy, and its development brings gospel to the recovery of tumor patients.
