An implantable nipple and areola prosthesis for post-mastectomy breast cancer patients includes a conical areola position bearing a matrix of suture holes and a protruding nipple portion. During post-mastectomy breast reconstruction surgery, a surgeon implants the prosthesis under the pectoralis major muscle, placing the implant with the nipple prominence anterior and areola portion posterior. The prosthesis is fixed with dissolving sutures in a circumferential fashion through suture holes in the areola portion of the implant. Scar tissue stabilizes the implant and once healed, cosmetic tattooing may be performed to create a realistic areola and nipple.
