This is a good place to start researching. AIUI, the lump usually
forms shortly after vaccination and instead of going away in a day or
a week or a few weeks, goes on to become a cancerous tumor. The link
I provided gives some good information.

~3 months to ~3 years after vaccination.

You know of any other sites regarding non-vaccination related
sarcomas? Our polydactyl has just has a rear toe amputated
because of a fibrosarcoma and I'm looking for more info.

Poor Footer now has only 23 toes.

Thank you, Laura and Phil. Some of the web sites you mentioned were ones
I had discovered on my own; some others were new. The information I had
read said "several months", but AFAIK none of them said "years." D.J.
was vaccinated for FeLV in May-June (same time as rabies and the other
vaccination whose proper name escapes me right now) of 1999 (when I
adopted him) and 2000 and possibly 2001 (I stopped after the vet
mentioned the potential for injection-site sarcoma, because except for
those occasions when he would dash out the door when it was open--and
then frequently upon discovering he was indeed outside turned back to
pound on the door to be let back in--he was entirely but definitely not
in 2002 (though he did get the other shots then). This year, he
developed a lump on his back between his shoulders which appeared
literally overnight.
