Tuberous Sclerosis

Tuberous sclerosis, also called tuberous sclerosis complex (TSC), is a genetic, life-long condition that causes lesions and benign tumors in your organs (mainly the brain, eyes, heart, kidney, skin and lungs). These lesions and tumors grow because your body's cells reproduce when they shouldn’t. The tumors may have been present when you were born or may develop at any time throughout your life.
