right breast growth in male

I had been ill with various sympotms for the last three weeks. Just started feeling good again.Energy up, good appetite, even some weight gain! Now I have noticed my right breast seems to have grown as if it is retaining fluid. I also am having intermittent shoulder, mid back, arm and chest pain. No cough, breathing is fine. Quit smoking 2 months ago after 25 year habit of 1 1/2 pack a day. I am freaking out at the possibility of lung cancer. I have heard that in some cases male breast growth is a symptom of lung cancer. I dont know if im talking myself into this or what. I have always had a bit of a chest to begin with. Passed down from dad and grandpa. But this seems more than im used to.Anyone else ever have these symptoms?

Enlarged breasts in males is most commonly from increased adipose (fat) but in rare cases can be from hormonal influences either endogenous (from your own body) or exogenous (from external exposure such as workers at an oral contraception manufaturing plant).

Cancer is an uncommon cause for male breast enlargement.

If you're concerned, it's worth having it examined by a physician.
