The British have always done this. They killed a friend of mine. Raye had metastatic melanoma (it was in her lymphatic system). My (US) doctor tells me that chemotherapy and beta-interferon are standard treatment for metastatic melanoma. The British doctors removed the mole and cancerous lymph node, telling Raye she required no further treatment. She died less than a year later when the cancer metastasized to her brain.
1/3 of all heart attack patients in Britain never see a cardiologist. I literally had to fight the doctor to get a strep screen for my son (we lived in GB for 5 years).
Imagine if your HMO controlled doctor training and could teach doctors that everything was unnecessary. THAT's healthcare in the UK.
