I have a nodule in my left lung that has been there all of the time. On my last PET scan it decided to light up. My surgeon would not do surgery until he found out exactly what it was. Connie B told me not to worry about it and that it was probably scar tissue. I told the surgeon what she said and he said that was quite possible, BUT he had me to have a biopsy on it anyway. My oncologist and radiologist both thought that it was scar tissue, but hey they were not doing the surgery. The biospy showed the nodule to be scar tissue, so I was able to have my surgery and am currently NED. So I know for sure that those nodules do not have to be bad news. The oncologists have experience with these things and when they are not overly concerned about them I think that is a good thing. Connie B. thank you so very much. I learned to think positive and believe here at this site. I hope that I can offer encouragement to someone else.
