I have a lung condition, bronchiectasis, along with mycobacteria avium complex (bacterial condition). I have lots of nodules, and have had to have part of my lower right lung removed about 6 yrs ago. I have CT scans regularly to monitor the nodules. About 6 mo ago I got a CT result that nodule in left lung had rapidly grown to 1.2 cm and was now classified as a spiculated mass. I also learned of the 90% malignant statistic, instant anxiety except I had been warned that the mycobacteria condition can sometimes become cancerous, OR appear cancerous when it isn’t. I went 5 mo. with no answer from docs regarding cancer. Did the biodesix blood test to determine chances of cancer, but it was mid range, which means maybe, maybe not. After a UPenn visit the CT was repeated in late January. It bears mentioning that a few weeks before UPenn visit my worsening respiratory condition rapidly declined. I had to take steroids, which I am supposed to avoid. I was also given a bronchodialator/steroid inhaler. I did improve prior toUPenn visit and was probably clearer breathing and felt better than I had in years….those amazing steroids I have to avoid. Result of repeat CT after that treatment, showed NO spiculated masx at all. Mass was now back to nodule, although continues to slowly grow, now 1.5 cm. I think I possibily had walking pnuemonia for months and because I deal with ups and downs with my condition didn’t realize how sick I was until so sick doc thought I would end up in hospital. That bad CT was taken during that period and radiologist probably did not look at my history to recognize that it may NOT be a spiculated mass. I have spoken to others with my condition or other lung conditions that state they have spiculated masses that are being followed. I could have had a PET scan or biopsybut did not want to expose myself to all that radiation unless absolutely strong possibly of cancer, due to my regular over exposure of CTs. In fact, a PET scan was scheduled but cancelled after 2nd CT that showed no spiculated mass.
