Tuberculosis will not develop into lung cancer in general. Tuberculosis is caused by Mycobacterium tuberculosis infection, which is a benign disease and has no direct relationship with lung cancer. Most patients will not develop lung cancer, but only a small number of patients will develop cancer due to the stimulation of mutation of cells because of the long term lack of treatment, but it is rare. Moreover, there are targeted treatment drugs and programs for tuberculosis, and most patients can still recover after taking anti-tuberculosis drugs such as isoniazid, streptomycin, ethambutol, etc. After cured, it will not turn into lung cancer naturally, so we don’t need to worry too much and follow the doctor’s instruction.
