Thank you again . Yesterday I was calm and collected , today I am in panic mode and cannot shake it off . What is worrying me more than anything is that this damned lump is right by the bone, practically on it and so getting margins is going to be so difficult . With Mast Cell , like other cancers , good margins are so important and thankfully last time, Reuben had lots of spare skin in the location but this time , well , there is no spare skin at all . I appreciate that I am no Vet , but I do know about mast cell cancer as I read extensively two years ago , margins are the key . Sorry , I must sound such a prophet of doom but this boy is my world , I lost Sam aged six almost 7 years ago and it is preying heavily on my mind , just needed to write my thoughts xxx
