My Husband Has Been Tested For Polytheism With A Bone

My husband has been tested for polytheism with a bone marrow extraction and CT scan and cancer was not diagnosed, however he continues to require blood letting, and was diagnosed with sleep apnea. His red blood cells continue to stay elevated, and he is 100 percent with his night time breathing. We are concerned, as in addition, he has also lost 38 pounds and living healthy. Would you comment on this? Next step?
