The three most difficult cancers to treat

Pancreatic cancer is a malignant tumor that occurs in the gastrointestinal tract. When patients show pancreatic cancer, the treatment may not be particularly good. The second is cancer that occurs in the liver and lungs. For liver cancer and lung cancer, early treatment may be better. However, once it develops to an advanced stage, the patient still shows metastasis and diffusion of distant organs. At this time, even if active treatment is carried out, the survival time is relatively short, and the patient only has a survival time of about half a year.
