Single Mastectomy Bra: What To Look For

Finding a comfortable bra to wear after a single mastectomy for breast cancer can present unique challenges. One side of the bra needs to support the remaining breast. The other side should either lie flat, be open, or have a pocket for a breast prosthesis. The good news is that there are single mastectomy bras designed specifically for this purpose.

“My new bra arrived, and I’ve been able to wear it a few times,” one MyBCTeam member wrote. “It’s comfortable and supports my one breast.”

 

Here’s what to know when shopping for a single mastectomy bra.

Finding a Single Mastectomy Bra

After a single mastectomy, also called a unilateral mastectomy, the two sides of the chest have different needs. A standard bra, or a bra designed for someone who has had a double mastectomy, may not provide the right fit or support.

A single mastectomy bra is designed specifically for this purpose. One side supports a natural breast. The other side may be designed to be flat, have an open space, or hold a breast prosthesis (also called a breast form). A good fit can help create balance and distribute weight evenly to protect against alignment or posture issues.

“I’ve tried so many bras, but the prosthesis doesn’t stay put,” one MyBCTeam member shared. “I walk hunched over or have to lean to one side.”

Your bra needs may change as you heal. Some people start with a front-closure compression bra during the first recovery stage. Later, they may transition to a pocketed bra or another style that feels comfortable to them.

As you shop, keep in mind that you may need more than one type of bra. Also, it can be helpful to purchase a few different kinds to try out and see which works best for you.

 

Key Features To Look For

The right bra for you will depend on your body shape, recovery stage, and whether you choose to wear a breast prosthesis.

Features that people often find helpful include:

  • Pockets to help keep a breast prosthesis securely in place
  • A no underwire design, as often seen in bralettes or sports bras
  • Wide, padded, and adjustable straps to help distribute weight evenly
  • Soft, breathable fabric, such as cotton
  • Front or easy-access closure, especially during recovery
  • A wide, supportive band that helps keep the bra in place

Some people find they don’t need every feature. One MyBCTeam member chose a single mastectomy bra without a cup on the flat side. “The best part is there’s no need for a prosthesis because there’s no cup,” the member shared.

Another member found that a new bra wasn’t necessary. “I had a single mastectomy, and I just inserted the prosthesis into my sports bra,” they said.

The best bra is the one that fits comfortably and meets your individual needs. If you need a new bra after breast surgery, you have options.

Getting Fitted for a Postmastectomy Bra

You may need to shop online to find the widest selection of postsurgical bras. But if you have a certified mastectomy fitter in your area, a professional bra fitting can help ensure you have the right band size, cup size, and style for your body shape.

“I went to a bra fitter who measured me for both the bra and prosthetic,” one MyBCTeam member said. “She also showed me different styles so I could choose what I felt most comfortable in.” 

To find a certified mastectomy fitter, start by asking your care team for recommendations. If you’re part of a breast cancer support group, ask other members about their experiences. You can also contact the American Cancer Society and other nonprofit organizations for help.

Will Insurance Pay for It?

Coverage varies by insurance plan. Under the Women’s Health and Cancer Rights Act (WHCRA), most group health plans and insurers that cover a single or double mastectomy must also cover the cost of related services and garments. This includes breast reconstruction, breast prostheses, and mastectomy bras.

Medicare also provides coverage for certain mastectomy bras and breast prostheses when they are medically necessary.

Before purchasing a bra or breast prosthesis, check with your insurance provider to find out what they’ll cover and how often. You may need a prescription or other documentation from your healthcare provider.

Finding the right bra after a single mastectomy may take some trial and error, but it’s usually worth the effort. The right fit can make a big difference in your comfort, confidence, and quality of life.
