Apologize, this was an older comment and I can't figure out how to delete it. Did not notice the 2024 date.

For me, it was difficult not to worry if it was cancer or not. I feel this "waiting" part of cancer process was the hardest thing for me. I'm also a female who is 71 yrs old and the 3.3 cm mass was found incidentally. I didn't even have any symptoms except that I had lost a lot of weight. I'm glad you have found this forum bc there are a lot of people who have real personal knowledge they are able to share that I have found extremely helpful. There are folks who find these are benign masses and unfortunately some discover that they do have cancer. Having a biopsy and PET scan is the best way to figure it all out. Even after your biopsy, and it does show malignancy, you will have to wait until those results are examined to determine exactly what the mutation is. It's only then they will know what the better options are for any treatment if required. My mom always taught me "to hope for the best, but prepare for the worst". Please keep us posted how you manage. Lot's of people here care.

@catdoris -- Although it's not productive to worry, it's human nature when it comes to our health. == After being sick off/on for 12+ months I ended up with Pneumonia. It was the follow up chest x-ray taken to assure that the Pneumonia was gone, that found a 4 cm x 4 cm mass in my upper right lobe as well as Pulmonary Emboli! Although difficult, I was GRATEFUL for the Pneumonia, or it may never been detected, until too late. (I too had no symptoms.) Yes, CT scans quickly followed and finally a PET scan, it will provide the info necessary to determine what the 5 cm mass is as well as any other areas that may be affected, in your body, except your Brain, or maybe NO OTHER AREAS IN YOUR BODY!. == Should the outcome indicate cancer, be certain to have a Brain scan as well. Be GRATEFUL for the scan technology available. The waiting will be difficult, but unavoidable. Wishing you the BEST POSSIBLE OUTCOME FROM YOUR PET SCAN!

@catdoris I am only sharing my own experience. I have no symptoms either. I went to the ER because I hurt my back and they took chest x-rays and that’s where they found the tumors. I did a biopsy of my lungs but the idiot collapse my lungs and I was really struggling for a while and then they found out it was Cancer. It took quite a while. I started in May and I didn’t get my diagnosis until June and then I had surgery in September because it was doubling in size every month I got my right upper and lower lobes removed and some lymph nodes have test size and I went through Kimo and now Tagrisso
