i'm sure this won't come as a shock to you but you need to quit smoking. are you aware that if your lungs get compromised enough you can have a heart attack? you obviously need to see your doctor immediately to get that circular knot checked out - hopefully it's just a swollen lymph node (which typically happens when there's an infection/virus in your system or just getting over an infection/virus). as scary as it is you need to get in to the doctor to be checked. no one online is going to be able to give you an accurate diagnosis. you need an exam and tests performed. especially where cancer runs in your family i'm surprised you still chose to smoke - but again to reduce your risk you need to quit smoking. cancer runs in my family as well. my grandmother passed away from heart cancer - i saw the unimaginable pain she was in even with the hightest dose of pain medication - you do not want to go through this if you don't have to. please quit smoking and please get seen by your doctor asap. good luck.
