Hi matiga, Thanks for visiting HCM. X-ray suggestive of right upper lobe tuberculosis should be thoroughly investigated. usually tuberculosis is associated with constitutional symptoms like cough more than two weeks duraion, bloody sputum, weight loss, evening rise of temperature, night sweats etc but it is not necessary that they will be present. You must go for sputum for acid fast bacilli ( early morning sputum has got more yield). Two samples should be examined. Even if it is negative and a pulmonologist has strong suspicion treatment should be started considering the dreaded nature of the disease. You must go for xray hip joint anteroposterior view for the tubercular arthritis of the hip ruled out. You may also go for ESR (erythrocyte sedimentation rate) and montoux test for additional suggestion of the disease. Cancer usually occurs in elderly male smoker. If your doctor suspects it you must go for ct scan thorax for detailed picture.... Best wishes
