I’m 16 years old, 5’4 and 96 pounds, I smoke about half or less a pack a day, and I started smoking more within this year, I did on and off for about two or so years. I’ve recently gotten pains a little to the right of my left armpit, I’m thinking my lungs. I also started playing sports again this year, and supposedly that can make your lungs a bit sore. I was just curious if size mattered. Would I be more likely to develop lung cancer over someone who weighs more? I’m just obtaining symptoms, and am sore in that area.

I’ve been worried cause I seem to get really winded quickly when I sing now but I seem to breathe easier after I exercise.

I definitely have allergies that make it more difficult to breathe through my nose but I feel like its not just my nose anymore but my lungs just have less capacity (breathing through mouth feels better but still like I take in less air). i seem to breathe a tiny bit easier when I’m lying on my back too.

Do you guys think I can rule out lung cancer?

or will your lungs clean themselves out?

for instance if someone smoked weed for two months or the equall to 75 blunts.

are lungs pretty good healers/regenerators?

In a case of It is generated in the bronchial tube at the entrance of lungs.

My friends mom was diagnosed with stage 4 lung cancer and she is being very vague with her about the information she is giving about the cancer. she told her that she had the fluid drained from her lungs and there was no cancer cells in the fluid, but she says they doctors are more worried about the "tumor" than that actual cancer, so my question is, are the "tumor" and the "cancer" two different things?
can you use layman’s terms please? im medically illiterate
