False breast shape (prosthesis) after breast cancer surgery

Find out about temporary and permanent prostheses after surgery for breast cancer.

A breast prosthesis is an artificial breast shape that sits inside your bra to replace all or part of your breast.

Temporary prosthesis

If you have a mastectomy without breast reconstruction, your nurse will give you a lightweight fabric breast shape to put in your bra. This is often called a cumfie or softie.

You can wear it right after the operation if you want to, even if the area feels tender.

Some women are happy with their cumfie and continue wearing it instead of getting another type of permanent prosthesis.

Permanent prosthesis

About 6 weeks after mastectomy, once your scar has healed and you have finished any radiotherapy you may need, you’ll be ready for your permanent prosthesis. This is made from silicone.

You have the prosthesis fitted by the breast care nurse at the hospital where you had your surgery.

Many types of breast prostheses are available free on the NHS.

If you are a private patient, you might have to pay for this. Or you can ask for a referral to the NHS prosthesis fitting service. 

The breast shapes come in different sizes, shapes and colours. Most women should be able to find something they are happy with on the NHS. But if not, there is more choice available if you buy your own from a manufacturer. 

Special mastectomy bras are available. They have pockets to hold the prosthesis. But you don't normally need a pocket. If your bra fits well and has full cups (rather than a low plunge), you should be fine. You can have pockets sewn inside your own bras free of charge on the NHS, if you want to. Ask your breast care nurse about this.

To look after your prosthesis, you should wash and dry it daily.


You can wear your usual prosthesis or make your own swimming prosthesis by cutting an ordinary sponge to fit.

If you use your usual prosthesis, rinse it in clean water afterwards to get rid of any chlorine or salt.

If you use a sponge, you can discreetly press your arm against it when you come out of the water, to squeeze the water out. 

Many of the breast cancer organisations supply bras and swimwear for women who have had a mastectomy.

Partial prosthesis

Womb cancer is sometimes called uterine cancer by doctors as uterus is the medical name for the womb. Or they may call it endometrial cancer. The endometrium is the lining of the womb. Endometrial cancer is the most common type of womb cancer.

If you are looking for information about cancer of the neck of the womb (cervix), this is not the right section for you. We have a separate section about cervical cancer.

Getting a new prosthesis

You can get a new artificial breast shape every 2 years on the NHS. You might need a new prosthesis if yours gets worn or damaged. You might also need to replace it if you gain or lose weight.
