46, no smoker/healthy. pneumonia w. 6x5 lung mass, er dr called tumor, lung specialist say is not , but after 4 months has no clues. so what i do?

Another opinion: If the mass is still present and, as you say, the lung specialist has no clue, ask your physician for a referral to another specialist or facility for further studies to explain the mass

Hmm: The definitive diagnosis is a biopsy of this mass. You may want to talk to your doctor also about a CT scan. X rays alone are not sufficient. Good luck

Lung mass?: A mass in your lung needs to be evaluated. Perhaps the opinion of another pulmonologist (lung specialist) is warranted. Better to be safe than sorry you didnt follow up.

"watch" a tumor: taking repeated X-rays. In many cases a lung tumor turns out to be benign and harmless. A doctor should recommend a biopsy only when an initial test suggests an area of tissue in the body isn't normal.
