Bad emotional factors change the functional state of the central nervous system, causing the brain electric field to continuously produce a short circuit, issuing wrong password commands, causing cell mutations and causing cancer.
Virus infection factor (10%):
The pathogenesis of cancer with mental disorders has not yet been fully elucidated. Genetic, chemical, physical and viral infections are all related to the development of cancer. Many studies have shown that psychological factors play an important role in the incidence of cancer.

The occurrence of postoperative complications of cancer not only brings pain to the patients, but also further damages the body's immunity and anti-infective power, making cancer a viable opportunity for recurrence and metastasis.
Cancer patients not only have to endure the pain of radiotherapy and chemotherapy during the treatment of the disease, but also often suffer from the pain caused by a variety of cancer complications, the most common are nausea, vomiting, hair loss, bone pain, fatigue, depression, treatment Fear and so on.
