It is interesting that the death certificate is listed as anemia and hypercalcemia as being the cause of the death, with the multiple myeloma being a contributing factor rather than a cause. Does not say much for whoever wrote the Death Certificate there in San Diego. Anemia and hypercalcemia are well known effects of malignancies including multiple myeloma. So in reality it was the cancer that killed her and the anemia and hypercalcemia should have been listed as the contributing factors.
Clark died in a palliative care facility AKA hospice. You don't get there as a terminal patient without first being diagnosed with a terminal illness.
True, you cannot enter hospice without a doctor determining a life expectancy of 6 months or less with a terminal disease.
