There are several types of mastectomy prosthetics available, including: 

• External breast prostheses: These are silicone or foam devices that can be worn inside a bra to provide a natural appearance and feel. They come in various shapes, sizes, and skin tones to match the individual’s appearance. 
• Internal breast prostheses: These are devices that are surgically implanted into the chest to provide a permanent solution for breast reconstruction. They can be made of silicone or saline and come in a variety of shapes and sizes. 
• Weighted breast prostheses: These are designed for women who have had a mastectomy on one side and require added weight to balance their bodies. They are usually heavier than standard external breast prostheses. 
• Custom breast prostheses: These are made to fit an individual’s unique shape and can be created using a mold or scan of the remaining breast. 
• Swimwear breast prostheses: These are designed specifically for women who have had a mastectomy and want to swim or participate in other water activities. They are typically made of foam and come in a variety of shapes and sizes. 

It’s important to note that the type of mastectomy prosthesis you choose will depend on your individual needs and preferences. Some women may choose to wear a prosthesis for comfort and to restore their appearance, while others may choose not to use one. Your doctor can provide additional guidance and recommendations based on your specific situation.
