Thanks, Lena! Since I asked about it, we’ve had a few developments. Needle aspiration path report says spindle cell (fibrosarcoma or hemangiosarcoma). Vets think it’s hemangio. Path report also said that because it is a peripheral tumor, it will be slower to spread. Her choices are to remove the leg, which she is adamant about not doing, or go to an oncologist. Univ of Ga is the nearest one, and she can’t afford to go that route. So I’ve ordered the Yunnan Paiyao and artemisinin, and hoping it can provide some palliative care. All bloodwork is fantastic, as is his energy. Hoping it helps. Thanks again!
