Constantly dealing with cysts!

My 9 year old basset has so many cysts. She had 4 taken off a year ago. Now she’s got about 4 more growing in different spots. I’m taking her to our vet because one on her side that she has scratched raw. Im sure we’ll be doing surgery again. Wondering if anyone has this issue. I hate to think she has to have surgery every year for these crazy things. Her sister has had only one removed. She’s not as bad. So frustrating!
