The naked mole living in East Africa is a strange animal. It is not only one of the only two mammals in eusociality, but also famous for its long life and cancer-free, so it has become a good animal model to study aging and cancer. However, a new study shows that naked moles can also cause cancer.

Researchers from the United States reported two cases of cancer found in captive nude moles in a paper published in Veterinary Pathology. In the first example, the researchers found a lump under the skin of a 22-year-old male naked mole, which was confirmed by pathological analysis as adenocarcinoma. There were no other major health problems before this naked mole, and everything was normal after surgical resection of the tumor. In the second example, a 20-year-old male naked mole was euthanized due to serious skin problems and weight loss. When the researchers dissected the corpse, they found a neuroendocrine tumor in the stomach of the naked mole.

This report is the first time that a tumor has been found in a naked mole. The researchers said that although the probability of cancer in naked moles is much lower than that in other mammals, their research shows that naked moles do get cancer, so follow-up research is necessary. This discovery may affect some biomedical research based on naked moles.
