Home Care and Prevention

It is very important to follow the instructions given to you by your veterinarian. If your pet has a recurrence of signs, contact your veterinarian at once. Prognosis varies depending on the location, size, and ability to remove the tumor surgically.

There is no known prevention of most leiomyomas. Ovariohysterectomy (spay) will prevent the formation of uterine leiomyomas.
