Cancer can lead to easy aches and pains all over the body, but this is not necessarily a symptom of cancer; muscle strain, infectious diseases, rheumatic diseases, etc. can occur. Cancer is a consumptive disease, which leads to weakness of the body, and the symptom of generalized soreness may appear. However, generalized soreness is not a specific manifestation of cancer. For example, after strenuous exercise, a large amount of acidic metabolic substances accumulate in the muscles, and symptoms of soreness may appear. Infectious diseases caused by viruses, mycoplasma and other microorganisms attacking the body, such as mycoplasma pneumonia, viral pneumonia, etc., can also show symptoms of generalized muscle soreness. Polymyositis, systemic lupus erythematosus and other rheumatic diseases, may appear muscle pain, fatigue and other systemic symptoms. Therefore, we cannot assume that generalized muscle aches and pains are cancer, and we suggest going to the hospital and being diagnosed by a professional doctor to determine the cause of the disease and then undergo treatment.
