Does anyone have any info that may help? My Akita Gizmo, gorgeous and cuddly, has a "bear" face (just love him so much), has a massive lump on back of his neck. It is about the size of a child sized basketball. To top it all off I found a baseball sized one on his side just about the start of where his ribs are. Anyway, took him to vet who took samples, aspirated it, and sent to a Diagnostic Laboratory. Results of that was : Highly suspicious of Sarcoma. We are contemplating having the biopsy done. We were told that if removed it could spread if cancerous, but with the discovery of the new one today, I'm afraid it may have already. I believe he is 6-7 yrs old. If anyone else has been through something like this please give your thoughts. Thanks!
