Morphology

leiomyosarcoma = leiomyoma (opaque) = leio + myo + sarcoma

The term is specialized medical jargon, and while the components relate to muscle and tumor, the specific medical meaning is not transparent to non-specialists.

Etymology

Leiomyosarcoma is made of three parts: leio- 'smooth', myo- 'muscle', and sarcoma 'fleshy tumor', a kind of cancer. So a leiomyosarcoma is a cancer that starts in smooth muscle, which is why it often appears in places like the womb, gut, or bladder.
