Is capsular contracture in lump form in one spot? Is this the beginning & is it going to get worse? 1 year post op (Photos)

Breast augmentation done in July 2016. I noticed a large lump on my left breast on the outside closest to my arm. The lump is hard and came about recently. I saw a specialist who said it is not a cyst and will require more testing (mammogram, ultrasound). He said it is very rigid and I can basically grab it. Im wondering if this is capsular contracture? Can capsular contracture be in one large lump that is rigid and painful? The rest of the breast is soft and doesn't look out of shape.
