I m 68 years old.. I had a 3 cm soft tissue attenuating mass on my 1st ct scan and after 6 months also it came to be 3.1 cm size.. Almost same size.. but in 2nd scan, some few subcentimetric intrapulmorary soft tissue nodules largest measuring 4mm were also present.. I skipped biopsy as it involved high risk and I'm unfit for needle biopsy.. The size not increased so does that mean it is Not Cancer? Can I rule cancer out? Or do I need to repeat scan again?
