There are many cancers that may cause generalized body aches and pains, which are mainly caused by the production of biologically active substances by cancer cells and are not directly related to the primary tumor or metastatic lesions. Like lung cancer, breast cancer, stomach cancer, colorectal cancer, cervical cancer, prostate cancer, lymphoma and multiple myeloma, etc., it is possible to have generalized body aches and pains, and such symptoms may even appear before the malignant tumor is detected. If the pain is severe, oral pain medication can be taken for treatment. Meanwhile, with active anti-tumor treatment, if the tumor is controlled, the biologically active substances produced by cancer cells will be reduced and the generalized aches and pains may be relieved or even disappear.
