A tumor or abnormal growth composed of or related to milk-secreting tissue.
From Greek 'gala' (milk) + '-oma' (tumor or growth). Medical terminology using the standard -oma suffix for any kind of abnormal mass or neoplasm.
In medical terminology, -oma always means tumor, so a galactoma is a milk-related tumor—but remember that not all tumors are cancer, some are benign growths.
