My 8 year old Labrador Retriever has had a few lumps on her and was checked to see if it was cancer years ago by autopsy and it wasn’t but recently I’ve noticed one growing on her head and bleeding. Should I be worried?

Thanks for using Petco Pet Education Center, formerly Petcoach! I think you should have this checked. The fact that it was previously known to be benign, does not mean that now it cannot be malignant. If it has gotten bigger, it would be great to sample it again. I recommend you have Lily evaluated by your veterinarian for a test called fine needle aspirate which is an easy, quick and pain-free procedure which in the majority of cases will help reach a diagnosis to identify what the best course of action is based on the findings. In some cases, a biopsy is needed for a diagnosis. If it truly is benign then removal is not necessarily recommended. However, if it is malignant and it has not spread to other locations, then surgical removal is recommended. Good luck! Keeping my fingers crossed that it is something benign.
