Mammary tumors in cats develop as a consequence of periodic spikes of estrogen, a female hormone. The increase in the levels of estrogen takes place during the heat cycle of female cats. This is one of the important reasons why veterinarians recommend that cats be spayed at about 6 months of age or before they reach sexual maturity and have their first heat cycle. Spaying virtually eliminates the potential risk of developing mammary tumors.
Female cats that are older than 6 months old with mammary tumors can still benefit from being spayed. Most experts believe that spaying at this age won’t prevent the development of mammary tumors, but it can eliminate the risk of developing pyometra, which is a life-threatening infection affecting the uterus. If your pet is in this situation, it’s a good idea to sit down with your vet clinic Cherry Hill NJ and discuss all the pros and cons, and what would be the best option for your pet.
