Plural of fibroma; benign tumors made up of fibrous or connective tissue that grow slowly and are usually not dangerous.
From Latin fibra ('fiber') + Greek -oma ('tumor'). The term entered medical vocabulary in the 1800s as doctors developed microscopes to examine tumor tissue structures.
Fibromas are like unwanted LEGO structures your body builds—annoying and unsightly but almost never malignant, so they're the 'safest' tumor a person could develop.
