Breast reduction surgery is a procedure used to treat women with breast hyperplasia (enlargement), where breasts are large enough to cause problems like shoulder girdle dysfunction, intertrigo and adverse effects to quality of life.
The NHS will only provide breast reduction for women if all the following criteria are met:
- The woman has received a full package of supportive care from their GP such as advice on weight loss and managing pain
- In cases of thoracic/ shoulder girdle discomfort, a physiotherapy assessment has been provided
- Breast size results in functional symptoms that require other treatments/interventions (e.g. intractable candidal intertrigo; thoracic backache/kyphosis where a professionally fitted bra has not helped with backache, soft tissue indentations at site of bra straps).
- Breast reduction planned to be 500gms or more per breast or at least 4 cup sizes
- Body mass index (BMI) is <27 and stable for at least twelve months
- The woman must be provided with written information to allow her to balance the risks and benefits of breast surgery
- Women should be informed that smoking increases complications following breast reduction surgery and should be advised to stop smoking
- Women should be informed that breast surgery for hypermastia can cause permanent loss of lactation
Unilateral breast reduction is considered for asymmetric breasts as opposed to breast augmentation if there is an impact on health as per the criteria above.
Surgery will not be funded for cosmetic reasons. Surgery can be approved for a difference of 150 – 200gms size as measured by a specialist. The BMI needs to be <27 and stable for at least twelve months.
Resection weights, for bilateral or unilateral (both breasts or one breast) breast reduction should be recorded for audit purposes.
This recommendation does not apply to therapeutic mammoplasty for breast cancer treatment or contralateral (other side) surgery following breast cancer surgery, and local policies should be adhered to. The Association of Breast Surgery support contralateral surgery to improve cosmesis as part of the reconstruction process following breast cancer treatment.
Gynaecomastia: Surgery for gynaecomastia is not routinely funded by the NHS. This recommendation does not cover surgery for gynaecomastia caused by medical treatments such as treatment for prostate cancer.
Rationale for recommendation
One systematic review and three non-randomized studies regarding breast reduction surgery for hypermastia were identified and showed that surgery is beneficial in patients with specific symptoms. Physical and psychological improvements, such as reduced pain, increased quality of life and less anxiety and depression were found for women with hypermastia following breast reduction surgery.
Breast reduction surgery for hypermastia can cause permanent loss of lactation function of breasts, as well as decreased areolar sensation, bleeding, bruising, and scarring and often alternative approaches (e.g. weight loss or a professionally fitted bra) work just as well as surgery to reduce symptoms. For women who are severely affected by complications of hypermastia and for whom alternative approaches have not helped, surgery can be offered. The aim of surgery is not cosmetic, it is to reduce symptoms (e.g. back ache).
Information for Patients
Surgery to reduce the size of your breasts is a procedure which should only be carried out when specific criteria are met. This is because the medical evidence tells us that the operation can sometimes do more harm than good, especially if you are overweight or if you smoke and there are other treatments which can be more effective.
About the condition
Large breasts can cause several problems for women. They can affect daily living and prevent an active lifestyle. Many patients report pain in their back, neck and shoulders. Some patients may get a rash or infection under their breast tissue. Having large breasts may mean it’s difficult to find clothes that fit and are comfortable.
It’s important you and your doctor make a shared decision about what’s best for you if your breasts are so large they are causing you problems. When making that decision you should both consider the benefits, the risks, the alternatives and what will happen if you do nothing
What are the BENEFITS of the intervention?
Breast reduction surgery may improve your mobility and make everyday activities easier, but it can only be carried out in specific circumstances and when other options have been tried and shown not to work.
What are the RISKS?
Breast reduction surgery is a major operation. There is a risk of complications which can include, bleeding, infection, significant scarring, loss of the nipple, alteration to nipple sensation and problems with breast feeding. A cup size cannot be guaranteed. These risks are greater in smokers and patients who are overweight.
What are the ALTERNATIVES?
There are lots of alternatives you should try first. These include losing weight, having a professionally fitted bra, pain relief, physiotherapy or seeking psychological support.
What if you do NOTHING?
Doing nothing is not likely to be harmful and you should try the alternatives to surgery first.
