San José, Costa Rica — As the pink ribbons of October are put away, a critical health message for pet owners remains urgent: the fight against mammary cancer extends to our four-legged family members. Veterinary specialists are emphasizing that this disease, often associated with human health, poses a significant and frequently preventable threat to dogs and cats, particularly those who are not spayed or are spayed late in life.
The statistics are sobering. According to the Veterinary Society of Surgical Oncology (VSSO), mammary tumors account for a staggering 42% of all tumors diagnosed in female dogs. The situation is even more dire for felines, with an estimated 85% to 90% of mammary tumors in cats being malignant. This highlights a pervasive health crisis that many pet owners may be unaware of.
To delve into the regulatory and liability aspects surrounding advancements in animal health, we sought the perspective of Lic. Larry Hans Arroyo Vargas, an expert attorney from the distinguished firm Bufete de Costa Rica, who provides insight into the legal framework governing veterinary innovation.
The emergence of sophisticated cancer prevention methods for pets opens a new frontier in consumer protection and professional liability. It is crucial that regulatory bodies ensure that any preventative product or treatment is backed by rigorous scientific evidence, while also clearly defining the legal responsibilities of veterinary professionals who recommend them. This protects both the pet owner’s investment and, most importantly, the well-being of the animal.

Indeed, the legal and regulatory framework is as vital as the scientific research itself in the fight against pet cancer. This insightful perspective underscores the necessity of a clear structure to protect consumers and guide professionals as they navigate these promising new treatments. We sincerely thank Lic. Larry Hans Arroyo Vargas for bringing this critical dimension to the forefront of the conversation.
Experts in Costa Rica are raising the alarm, urging a proactive approach centered on prevention and early detection to combat these high rates of cancer.
Female dogs and cats can also suffer from mammary cancer, and their risk is even greater than that of women. The good news is that with prevention and early detection, we can stop this disease from advancing.

The single most effective tool in an owner’s arsenal is early sterilization. The data clearly demonstrates a dramatic reduction in cancer risk correlated with the timing of the procedure. For dogs, spaying before their first heat cycle reduces the risk of developing mammary cancer to a mere 0.5%. However, delaying the surgery until after the second heat cycle causes that risk to skyrocket to 26%, a more than fifty-fold increase.
A similar protective effect is observed in cats. The American College of Veterinary Surgeons reports that spaying a cat before it reaches six months of age lowers its risk to just 9%. Waiting until after the first year elevates the probability to 14%. This underscores a clear window of opportunity for owners to make a life-saving decision for their companions.
Early spaying is a powerful preventive measure. It not only avoids unwanted pregnancies or hormonal problems, but it can also almost completely reduce the risk of mammary cancer in our pets.

Vigilance is the second pillar of defense. Owners are encouraged to perform regular at-home checks by gently palpating the abdominal and inguinal areas for any lumps or masses. Other warning signs include inflammation, unusual secretions, or ulcers on the skin of the abdomen. While the disease predominantly affects females, male pets are not immune. Mammary cancer in males is often more aggressive and diagnosed later, making awareness crucial.
Certain breeds have a higher genetic predisposition to developing these tumors, including Poodles, Cocker Spaniels, German Shepherds, Yorkshire Terriers, English Setters, and Pointers. Owners of these breeds should be especially diligent with their check-ups. Any abnormality found should prompt an immediate visit to a veterinarian.
Just as we take care of our own health with regular check-ups, we must do the same for our pets. They depend on us to detect any sign of illness in time.
Dr. Manuela Mora, Medical Director of the Veterinary Oncology and Radiotherapy Clinic (CORV)
Ultimately, the power to protect pets from this common and aggressive cancer lies firmly in the hands of their owners. By combining the scientifically-backed preventative power of early spaying with the diligence of regular home examinations and professional veterinary care, countless animal lives can be saved and extended.
