Should I Tell to my Fiancee Before Marriage, That Keloid Scar is in my Stomach ?

I have a 2 inch scar with keloid affected area about 1 inch on my stomach (operated about 15 yrs before). I have been taken steroid for 6 times recently. But still an half inch keloid afftected area not cured. My Doctors said it will cure slowly and also told no need to tell to better half before marriage. I expect ur answer.
