Tuberculosis and tumor, which are two different diseases, are very different. Tuberculosis is a respiratory infectious disease, mainly due to infection with Mycobacterium tuberculosis, resulting in a series of symptoms in the lungs, such as low fever in the afternoon, night sweats, wasting, general weakness, depression, cough, sputum and hemoptysis. Once TB is diagnosed, it should be treated with long-term standardized anti-TB therapy. Tumors are caused by various factors, such as smoking, inhalation of harmful particles, and radioactive factors. There are benign and malignant tumors, and different treatments such as radiotherapy, chemotherapy, surgery or combination therapy should be taken according to the type of pathology.
