Your history does sound like lung cancer. The lung biopsy is done under general anesthesia. You may cough after that for several minutes. That's normal. They should remove enough and in different areas for the biopsy. They should take enough that they can test for mutations. I only smoked for about 16 years, since age 15 to age 31. I'm 68 now. I was diagnosed in the fall of 2025. I had a CT of the abdomen and an incidental finding saw the nodule. I saw a pulmonogist about a month later and had a negative biopsy a month after that. I went for a follow up biopsy in December 2025 and that was positive for non small cell lung cancer (adenocarcinoma). I started chemo and targeted treatments in January 2026 and I'm doing pretty well, considering. Good luck to you. I am on the lung cancer support group here. The people there are very nice and very helpful, especially with the questions and concerns about treatment. Sometimes, doctors don't know as much as the patients about side effects (although they vary from person to person) and how things may occur medically.
