Re: lump from injection site - dangerous?

[Andrew Werner]

Hideyo,

My apologies for jumping right in - I'm new here and ought to have the grace to introduce myself first, but I don't.

As someone already wrote, the lump might just be a passing reaction - sometimes the vaccination site forms a little lump for a short time and it goes away, no problem.

Other times - we had a cat named Frisco who had a vaccination site fibrosarcoma.  She had radiation and chemotherapy and it got her four good years, but the fibrosarcoma came back eventually, and there was nothing more to do.  It was very sad.  You can find more if you search on "vaccination fibrosarcoma" on the web.  Our experience was some years ago - there may be more up-to-date information out there.

If you can, please have your Vet look at the lump, and maybe take a little sample for biopsy.  If it is indeed a fibrosarcoma, it is important not to disturb it surgically too much, so it can be targeted for radiation if you go that route.  I really hope it is not.  Hang in there.  Purrrs for Dharma.

Purrrs,
Andrew

Hi, I need your help --- I just noticed that my Dharma, whom I have been treating for possible FIP, developed a lump around neck shoulder area --- I have been giving different injections, interferon, sub q fluid, vitamin B.. and etc.. and am not sure exactly if this is the location.. but I am wondering if it’s caused by injections .. and if so – should I worry about this? I heard  before that injections (any) can cause cancers and I am very worried..now.. I would appreciate any insights… thank you!
