Sometimes I experience pain in my left chest. I'm worried that it might be related to smoking. Of course, when I smoke less, the pain seems to lessen, so I think there is definitely a connection. I also have some family history of lung cancer, so I need to seriously consider quitting smoking, but it's not easy. Please advise me on methods that can help with quitting smoking.
