A sis is a bump which women may get on their breast which is just a build up of fluid but often thought to be a cancerous bump.
My aunti went to the doctors yesturday to see about that bump on her lower breast but it wasnt cancer, it was a sis thank God.

NOT your HALF sis, or your STEP sis, but your REAL, GENUINE, GENE sis! She got ALL of her genes from the same two people you did!
The title "gene sis" is normally irrelevant, unless you are already mentioning your half sis, step sis, bridge sis, side step sis, or skip sis.
