Hello there - I'm not sure if this is the correct place to ask but our Chloe had a front right amp three and a half weeks ago for osteosarcoma. Her recovery has been steady and uncomplicated. However, she has developed four of what her surgeon called sebaceous cysts on her neck, legs, and body. Does this have anything to do with her cancer or surgery? Is there anything I can do to help her? They don't seem to bother her at all but a couple of them have small amounts of drainage that may the fur.
