I would aggressively follow up with on this especially since it has increased in size. My mother was diagnosed last year with lung cancer. she had no symptoms until 2 months prior to the prognosis. THIS DOES NOT MEAN THAT YOU HAVE CANCER. I am just saying that you should follow through with determining what the nodule is. If it is benign then praise god, if it is malignant then odds are on your side that you caught it early and can aggressively treat it. Natezekri is right, there is alot of modern medicine out there that treat what ever the nodule is. It is normal to be scared, worried, confused. Educate yourself on your condition, ask many questions, get second opinions, and research the validity/options of all of the physicians opinions. Take control of the path of your medical issue.
Hi if you don't have symptoms you may not have it but i would definitely go to the doctor once a month to make sure it doesn't get bigger but if it does then there is a bunch of things modern medicine can do to prevent cancer don't worry eat healthy and get exercise. you will get better i will pray for you
