Breast Prosthetics
A breast prosthesis is an artificial breast form designed to mimic the shape and weight of a natural breast. Prostheses are made from materials like cotton, foam, or silicone, and are typically worn inside specially designed mastectomy bras for a natural appearance under clothing.
Some people wear a prosthesis temporarily while healing or considering reconstruction, while others use one long-term for comfort and balance.
Types of Breast Prostheses
-
Foam or fabric-filled prostheses are lightweight, breathable, and soft, making them ideal for post-surgery recovery, hot weather, or while undergoing radiation
- Soft, washable, and comfortable
- Adjustable size by adding or removing stuffing
- Can be worn directly against the skin or inside a pocketed bra
- Free options available through Knitted Knockers of Canada
- Best for short-term wear or for those looking for a light, breathable option.
"Knitted knockers have been a lifesaver for many women who have been diagnosed with breast cancer. They are sent to you free of charge. They are lightweight, and they don't feel as hot and sweaty as other prosthetics."

Silicone Prosthetics
Provide a realistic look and feel, making them a popular long-term choice
- Heavier, offering natural movement and improved balance after a single mastectomy
- Designed to closely resemble a natural breast
- Lasts 2 to 5 years with proper care
- Worn inside a pocketed mastectomy bra
- Hand wash only
- Not suitable for swimming; chlorine and salt water can damage the material
- Best for those seeking a realistic and long-term option
"I did go from the heavy ones (prosthetics) to a lighter set and find them much nicer. I have knitted ones and when it's warm I tend to use them as there is no weight."
~Annette~Look Good Feel Better offers a free online workshop on breast prostheses, bras and more.
