Depending on the type of implant you have- silicone, saline, or silicone/saline combined, there may be insignificant volume changes in the impalnt which will not affect the implant itself or the surrounding tissue. Research on the silicone and the saline implants showed a 1-4% increase within the small bubbles in the implant. The combination type showed a greater increase but no enough to cause damage.
Two other concerns are the chest straps on your BC, if overtightened can lead to rupture. The other is buoyancy. The saline is neutral while the silicone is negative. You may have to adjust your weight accordingly.
