The zoo first noticed something wrong with the 11-year-old ring-tailed lemur earlier this year when a keeper found swelling near her breast. After an examination from the zoo's director of animal health, Dr. Ginger Sturgeon, it was determined that the mass was breast cancer.

“Initial test results from Caera’s lumpectomy surgery showed that she had two separate tumors,” Sturgeon said. “One was a ductal carcinoma and the other was a tubulopapillary carcinoma. Unfortunately, based on the histopathology, Caera required a second and more extensive surgery but the good news is that Caera’s cancer is relatively low grade.”

Zoo officials said Caera is resting and will be returned to the Tropical Rain Forest Complex soon.

In the meantime, Caera will be monitored by Sturgeon and her team and given anti-inflammatory drugs.

"We are hopeful with this surgery that Caera will have a long, happy, cancer-free life. Animals are extremely resilient," Sturgeon said. "They have a great capacity to heal."

Dr. Jack Demos, founder and medical director of SurgiCorp International, assisted Sturgeon with the surgery.
