My husband saw a cardiologist a few weeks ago & during the visit, he recommended that my husband see a hematologist for his APS since he hasn't seen one before. One just happened to be at our hospital for his monthly visit when my husband's lungs were showered with clots & he was diagnosed with APS. When I went to make the appointment with the hematologist, I told the nurse that the cardiologist wanted him to see a hematologist for his APS & gave the doctor's name. She said okay, was quite familiar with APS & made the appointment. But when I looked at the appointment card, the doctor is an oncologist, not a hematologist. Has anyone heard of such a situation? Can an oncologist do both specialties?
