If aden- means gland, what word could mean a tumor of the sebaceous glands?

Aden- means gland and -oma means tumorous growth. Together, an adenoma is a tumorous growth of glandular tissue. Therefore, a tumorous growth involving the sebaceous glands is called a sebaceous adenoma. In cases of maligancies, it can either be a carcinoma (arising from the epithelium) or a sarcoma (arising from the stroma). If the sebaceous gland tumor turns out to be malignant, it is now called a sebaceous adenocarcinoma as it is a cancer arising from glandular epithelium.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
