Hi all. So my mum had a pet scan 3 weeks ago to investigate a mass in her upper right lung. She spoke to her consultant on the phone today and he explained that the scan showed the active area in the right side as expected but there is also a very small active area in her left lung (which didn't show up on the chest X-ray or ct scan) he said this is very unusual and the delay in getting the results was due to the report being looked at by a few consultants to decide on the best course of action. She will have a needle biopsy in the next week or so and also blood tests. My mum asked about potential treatment and he said surgery on the left and radiotherapy on the right side - does this sound right? The right tumour is about 1.5 inches so would they not remove that surgically and use radiotherapy on the left side which is very small? He also didn't mention chemo. I am also wondering if anyone can shed some light on why her case is unusual?
