Oregon Senators are considering a bill that would require doctors to receive the latest information and training on breast health exams with an aim to improve early detection of cancer. A doctor missed a cancerous mass during Diane Palser's breast exam. A year later, a different doctor told the Portland resident she was right; it was a lump and almost immediately Palser had a mastectomy. She says her case is just one example of how a lack of training can impact a patient's life.
