Hi, it's me again. I've been thinking. The 3 main remedies for bone cancer are
Heckla Lava, Phosphorus and Symphytum. Of these 3, only Phosphorus is also a kidney remedy! So, I might want to change my mind and go with Phosphorus instead of Symphytum, especially if your father has other Phos. keynotes, such as desiring icy cold drinks.

Sincerely,

Snoopy
