For anyone who is scared shitless by the posts about cancer being missed, which it clearly has been in the cases outlined above, I'd like to share my (well, one of) my cancer story.
I woke one morning with a slight ache in my shoulder blade and a tingling I my little finger. Thought I'd just slept "funny" but for reasons unconnected, I decided to see GP. surgery
After exam, she sent me for an xray. A week later, got a call from the surgery that "something" had shown up in my lung, probably scarring from chest infections.
But, because I'd previously had cancer, they thought it better that I go for a ct scan.
I had lung cancer. No cough, no blood, just a tingling sensation.
because they caught it early (and because of the type of lung cancer it was) I had an operation, and no further intervention was needed.
So, GPs do sometimes get it right, though my sympathy is with those of you who were not quite so lucky.
