Does leg ache feel weak to be related to cancer

Cancer

can cause an increase in basal metabolic rate, which consumes a lot of calories and is not conducive to maintaining normal activities of the body. As the disease gradually worsens, cancer cells will also metastasize or spread to other tissues, easy to infiltrate and invade the nerves under local tissues, resulting in leg soreness. However, if the patient has fever, it will consume more energy in the body, and it will also cause lactic acid metabolism disorder, resulting in a large accumulation of lactic acid in local tissues, which is easy to stimulate local nerves, so the above phenomenon will occur, which is generally unrelated to cancer.
