How common is Breast implant illness for tuberous breasts?

18 female, 5 foot 3 and 180 pounds. Despite my weight, my chest has never adjusted and I believe that I may have tuberous breasts. My breasts have been my biggest insecurity my whole life and I would do anything so that they look different. However, I have heard about a condition called BII, where the body attacks the outer silicone shell of the implant, causing autoimmune disorders and I am very scared. I would like to know what the risk for BII is with regards to tuberous breasts is. Thanks
