I have a theory

Hi, i have keloids on my breast. At some point they got really itchy. Then as an experiment i decided to stop consuming sugar completely.. and while that didnt change the size at all, they stopped itching completely, flattened, and softened. So i keep away from sugar but sometimes i get super mad and just eat whatever the hell i want.
except i just wanted to put it here because maybe the reduction of inflammation is what is helping? can someone confirm?
