Most have some type of cloth cover, like soft cotton. Others come with a latex cover. Some brands now offer a cloth pad on the back to absorb perspiration and keep you cooler. It's worth taking the time to find one that matches your other breast and is comfortable. If you really want to splurge, you can buy a custom-made prosthesis that is made specially for you, to fit the contour of your body and match your other breast.
Cost depends mostly on quality and brand.
A custom-made prosthesis will cost much more. If you want your health insurance to reimburse you, be sure to get a prescription from your doctor for the prosthesis. Prostheses last from two to five years. Most insurance coverage pays for two bras with a prosthesis pocket per year and a new prosthesis every two years. If you do not have insurance, check with the American Cancer Society.
