What kind of back pain is cancer?

Cancer is a malignant tumor disease, which normally has no obvious clinical symptoms in the early stage. With the gradual development of the tumor, it will cause invasion of various parts of the body, causing patients to show cancer pain. However, the symptoms of cancer pain are not classic, so it is impossible to judge whether there is a malignant tumor disease according to clinical symptoms. If it is suspected of malignant tumor, it can be diagnosed by pathological examination in regular hospital. In addition to pathological examination, other diagnoses are auxiliary diagnosis and cannot be used for diagnosis of disease.
