My mum has been unintentionally losing weight for some time. Finally she has seen her Gp . She only told us yesterday that she has had a chest xray and bloods and is seeing a consultant today. I’m so worried she may have lung cancer. She used to be a very heavy smoker and she now vapes instead . She has had two different cancers before plus a heart attack and stroke. She is 72. How long after a chest xray do you get a diagnosis.
