Getting a diagnosis of cancer can be frightening enough. But a new report warns, finding a doctor to treat you could become a new fear. ABC News reports it's a perfect storm of circumstances that could cost lives. Cancer is about to become the number one cause of death, just as an oncology shortage fueled by Medicare cuts looms. The American Society of Clinical Oncology warns cancer is about to surpass heart disease because advances in heart medicine and lifestyle changes are allowing people to live long enough to develop cancer. And cuts in Medicare are forcing smaller practices to close. They recommend a new health care delivery and payment systems that preserve small community practices, and new quality initiatives.
