Metastasizing fibroscaroma?

Question

We found out recently that our cat Kaele (a 10 year old DSH), has developed a vaccine-related fibroscaroma between her shoulder blades. We discussed our options with our vet, & we decided (along with the vet) that it was best not to put her through the surgery & radiation, given her health history. I was petting Kaele earlier this week, & discovered a second hard lump on the right side of her body (roughly 2-3 inches from the bigger mass) that is approximately an 1" x 1.5" in dimension. Would this indicate that the fibrosarcoma is metastasizing? I have a call in to the vet, but I'm still waiting to hear back. 

Even though we've discussed everything with the vet & continue to do so, this is just so, so overwhelming. I never imagined that vaccinations would be Kaele's undoing...

 There is a drug called Masivet, a friend of mine was giving it t her kitty, she thinks it gave her a few more good months with her boy.

I have seen a couple of these and they are devastating to witness.  Surgery was done  on these cats removing as much as possible, but they unfortunately returned.  The other lump you see is probably related to it also.  The link the other poster gave you actually has very good information on this.  If you have other animals or know other people that have cats inform them of this problem.  Current vaccine protocol involves giving the vaccines in the upper part of a leg - as indicated because if necessary the leg can be removed increasing the chance of a good recovery.  Verify the vet does the vaccine in the leg and not between the shoulders.  Vaccines are now also recommended every 3rd year or so.  The only vaccine that does occasionally cause a lump (and this is well known) is the rabies vaccine.  This vaccine is required and the lump (shows up a few weeks or so after the shot) actually goes away with time.  My vet actually gives all rabies vaccines ((both cats and dogs) in a specific place so if a lump appears he knows what it is and can advise the client.  I have not seen any cancer related to the rabies vaccine.

Give her all the love and attention you can.  I am sorry that you have to go through this - you have my best wishes.

The link proves what you feared happened and my heart goes out to you all, I can tell you love your pet and it's so painful to know you were helping her and she's now so ill. Please don't let her suffer anymore and it's possible the cancer has spread, my beloved cat was put to sleep as she had mouth cancer as there's mercury in the tuna that she loved which caused the cancer on her tongue etc, like you I felt guilty and it's our grief that makes us blame ourselves. I wish you all the best and I know you will do right by your cat.
