The high mortality rate of cancer may be due to the fact that it is more difficult to treat, or more difficult to detect early, and also there may be no effective anti-tumor treatment currently available. Currently, among all cancers, pancreatic cancer and liver cancer are more difficult to treat. The highest mortality rate may be pancreatic cancer, which is called the king of cancers. If it is inoperable in the middle and late stages, the survival period is usually about three months to six months, and some of them are less than three months. There are few obvious symptoms in the early stage of pancreatic cancer, some of them show symptoms similar to pancreatitis, which may include pain and discomfort around the upper abdomen and belly button, and some may have mild jaundice and other manifestations. The clinical diagnosis of pancreatic cancer can be made through the enhanced CT and MRI examination of the pancreatic area, which reveals the occupying lesion, combined with the tumor index glycoantigen 19-9 which may be elevated more. However, only early stage may be operated, middle and late stage are usually inoperable, and even if operated, the recovery effect is not very good.
