Generalized pain and weakness are not necessarily the early stage of cancer. Generalized pain and weakness can be caused by many reasons, such as cold, overwork, lack of sleep, etc. Generalized pain and weakness may also occur in the early stage of some cancers, but the symptoms are not typical. If it is caused by cold and flu, in addition to the symptoms of generalized pain and weakness, it will also be accompanied by fever, headache, nasal congestion, runny nose and other cold and flu symptoms, so it is necessary to measure the body temperature, and at the same time to conduct routine blood tests, if there are increased white blood cells and neutrophils, it means that there is a bacterial infection, and in addition to applying anti-cold and flu medicines to regulate the treatment, it is also possible to add anti-bacterial medicines. If the above symptoms are caused by overwork and lack of sleep, it is only necessary to reduce labor and rest more to relieve the symptoms. Individuals with early stage of cancer may have other symptoms such as loss of appetite, unexplained weight loss, etc., but most of them are atypical and should not be taken seriously. The symptoms of generalized pain and weakness cannot be equated with the early stage of cancer. If the symptoms persist without obvious improvement, it is recommended to go to the hospital in time for screening of tumor markers, so as to achieve early detection, early diagnosis and early treatment.
