Body and bone scans

I was having my yearly mammograms and doing everything I was told after my first diagnosis then I got a really sore leg, I  thought I had pulled a muscle in my leg at the gym but ir didn't get better so after almost 3 months of pain killers that did nothing for the pain and xrays that found nothing even though the doctor knew I had had cancer, they finally got around to a bone scan, well the tumour they found was so big it had almost eaten all the way through my bone and had to go into hospital immediately to have a pin put in my leg to stop it from fracturing as wel as multiple other tumours, I  am positive it would have been found much sooner if I had been having even bi annual bone and ct scans.
I wish now that I had insisted maybe it wouldn't have been as wide spread as it is now.
