Leukoplakia / Precancerous cells

I'm kind of scared right now, for the first time in my life. I'm 28 and was diagnosed with Leukoplakia and was told there was only 1 % chance it was cancerous.

My blood worked showed elevated white blood cells, out of normal range, and then my live blood sample showed one single solitary jagged cancer cell, which really scared me.

My Leukoplakia is right on my vocal cords.
