If the lump is getting bigger it may be worth taking her back to the vet to make sure that it's not infected. A tumor isn't impossible but fairly rare for a young puppy and more likely to be a vaccine reaction if that's where he gave it. Make sure the vet is fully aware as they may want to give her a Premedication before her next vaccines. You can try doing a warm compress on the lump to see if that may decrease some swelling. A warm washcloth every 6-8 hours for 5-10 minutes. I hope Moana is better soon.
