In any medical system, you have to advocate on your own behalf. My friend had skin cancer, and the doctors kept sending her away, and finally she walked into her doctor's office and said "If you don't get this off me, I'm going home to cut it off myself", and he removed the cancer. It was melanoma but it hadn't developed roots. Had she waited until some deemed it urgent, it would have been too late.
There are lots of stories of those who didn't stand up for the care they needed until it was too late, but just as many of those who successfully advocated on their own behalf and saved their own lives in doing so.
Thats pathetic.
Skin cancers are easy to detect.
