My implants are 35 years old and hard as a rock, also my breasts are very tender is this dangerous?

Capsular contracture is when there is abnormal scarring around your implant, tightening it and causing the breast to feel firm. The breast may also look abnormally round or elevated. This can sometimes be treated without surgery, but if the problem persists, you may need surgery. I recommend you go back to your surgeon to have your breast checked out as soon as you can. Best of luck.

Thank you for your question.  Based on your history you most likely have significant capsular contraction around your breast implants.  I would suggest an examination by a board certified plastic surgeon and and MRI examination to see if you have an implant rupture.  It is unlikely that your condition is dangerous however for your comfort implant removal might be an option.

Thanks for your question. Your condition is not
dangerous but does need medical attention. Implants that are 15 years old have
a 50% leak rate on MRI scans according to one study, and by 35 years, the
chance of an implant leak is quite high. The firmness of the implants is
related to excess scar tissue formed around the implants (capsular
contracture), which in its most severe form can be painful. The recommended
surgical procedure would be to remove not only the implants but the entire
capsule. The only medical risk from waiting is the chance that the implant
leakage could extend into the breast tissue, which would complicate removal but
would not make you systemically ill and in that sense is not dangerous. I
suggest you consult with a board-certified plastic surgeon. Best wishes.
