In ct i have a left hilar lymph node calcified not a smoker have chest pains and blood in sputum. no tb can this be cancer? is this common?

Possibly: although most calcified Tyler lymph nodes are caused by benign conditions such as infections ( for example histoplasmosis, tuberculosis) or diseases such as sarcoidosis, silicosis, they occasionally can be caused by cancer. It should definitely be fully evaluated by a pulmonary specialist.

Infection likely: Hemoptysis (blood in sputum) is a common pulmonary symptom (10-15% of all pulmonary visits). In less than 5% of cases, the cause can be life-threatening - but of that group, over 50% of patients will die without early evaluation and treatment. Aspergillosis is a common cause of hemoptysis, and should be ruled out. Your doctor may monitor with serial CTs or CXR if you do not have an infection.
