Due to family history I am classed as moderate risk for breast cancer and have been getting invitations for breast cancer screenings since turning 40. The letter usually comes in June for a July appointment. This year I didn't get the letter.
However! I rang up my hospital trust in July, they called me back a day later and arranged an appointment very swiftly for a routine mammogram. Got the results back within ten days, all ok.
What I am trying to say is this. We have to take responsibility for our own health and make these things happen. If you know you are supposed to have your routine check up, just ring your hospital and get it arranged! From my personal experience all got arranged swiftly and efficiently - but I had to make the first call, knowing that this year things are just different.
