I don't know how I missed this when you first posted it. I am glad all is well and Diesel is recovering! That does my heart good as I am sure it does yours. I wish him a continued speedy and full recovery.
Had I read this when you first posted, and for anyone researching later, I can say it is not true that only cancerous tumors on the spleen bleed. Thor had a mass that was not cancerous and he had several bleeds before it finally ruptured. Because of his heart issues he was not a surgery candidate. He lived 20 months after his diagnosis and most of it was of a good quality. Again I am so glad Diesel is doing so well.
