Can Liposuction Reduce Breast Size? Who It May Suit

Liposuction can reduce breast size in some women, mainly when the breasts contain a high proportion of fatty tissue rather than glandular tissue. It removes fat through small incisions but does not remove skin, reposition the nipple or reshape the breast. Women wanting a large reduction or a significant lift are usually assessed for surgical breast reduction instead.

How does liposuction reduce breast size?

Liposuction reduces breast volume by removing fat. A practitioner makes small incisions and removes fat with a thin cannula, sometimes after using ultrasound energy (Vaser) to loosen it. Your practitioner will explain where the incisions are placed.

Because only fat is removed, the amount of reduction depends on how much of the breast is fat. The technique, anaesthesia and recovery are explained on our breast reduction with Vaser liposuction page.

Why does breast tissue type matter?

Breasts are made up of fatty tissue and glandular (dense) tissue in different proportions. Liposuction removes fat well but does not remove dense glandular tissue in any meaningful way.

• Mostly fatty breasts may be reduced with liposuction. Breasts often become fattier with age, after menopause and with weight gain.
• Mostly glandular breasts are less likely to reduce noticeably with liposuction. These are more common in younger women.

Imaging such as a mammogram or ultrasound can help show the breast composition. Your practitioner will advise whether imaging is needed before any procedure.

Liposuction vs surgical breast reduction: what is the difference?

The two approaches address different goals. Liposuction removes fat. Surgical breast reduction (reduction mammaplasty) removes fat, glandular tissue and skin, and repositions the nipple.

	Liposuction	Surgical breast reduction
What is removed	Fat only	Fat, glandular tissue and skin
Breast shape	Not reshaped	Reshaped
Nipple position	Not repositioned	Repositioned
Lift	Any change from skin contraction varies and is not guaranteed	Lift is part of the procedure
Incisions	Small entry points	Longer incisions around the areola and on the breast
Anaesthesia	Local anaesthetic with sedation, or general anaesthetic, decided at consultation	General anaesthetic
Main suitability factor	High fat content, modest reduction wanted	Larger reduction, significant sagging, glandular breasts

Both carry risks, discussed below. Which approach is appropriate depends on your anatomy and goals, and this is assessed in consultation.

Who may be suitable for breast reduction with liposuction?

Women who tend to be assessed as suitable have breasts with a high proportion of fat, mild sagging, good skin quality and realistic expectations of a modest reduction. Suitable candidates may see a reduction in breast volume. Outcomes vary.

It may also be discussed for women with medical reasons to limit the length or type of anaesthesia, following assessment.

Liposuction is less likely to suit women who:

• have mostly glandular breast tissue
• want a large reduction
• have significant sagging or want the nipple lifted
• want a change in breast shape rather than size
• have an unexplained breast lump or abnormal imaging that has not been investigated

Some women report improvement in physical symptoms such as back, neck or shoulder discomfort after breast reduction. Outcomes vary and should be discussed with your practitioner.

Will liposuction lift the breasts?

It may give a small degree of lift in some women, but this cannot be guaranteed. Removing weight from the breast and the heat from ultrasound-assisted devices may cause some skin contraction. The extent varies between patients.

Women with noticeable sagging are usually assessed for a breast lift or surgical reduction, which reposition tissue and skin. For more on how skin responds after fat removal, see loose skin after liposuction.

Can you breastfeed after breast liposuction?

Liposuction aims to remove fat rather than the glandular tissue that produces milk, but any breast procedure may affect breastfeeding and this cannot be guaranteed. Not every woman is able to breastfeed, whether or not she has had surgery.

If you plan to have children, raise this at consultation. Our article on pregnancy after liposuction covers timing and how pregnancy can change results.

What about breast screening and breast cancer?

Any breast lump or abnormal finding must be investigated before liposuction is considered, which may involve imaging and a biopsy. If you have a personal or family history of breast cancer, discuss it with your GP before any breast procedure.

Breast procedures, including liposuction, can cause changes such as fat necrosis or calcifications that may show on later imaging. Tell your radiology provider about any breast procedure before screening.

Risks and considerations

All surgical and invasive procedures carry risks. Results vary between individuals. Material risks of breast liposuction include:

• bruising, swelling and discomfort
• bleeding, haematoma and seroma
• infection
• asymmetry in size or shape between the breasts
• contour irregularities
• changes in nipple or breast skin sensation
• fat necrosis, which can cause firm lumps that may need imaging or biopsy
• changes on future mammograms
• burns or skin injury with ultrasound-assisted devices
• scarring at incision sites, which varies between individuals (see scarring after liposuction)
• blood clots and reactions to anaesthetic or sedation
• a smaller reduction than hoped, or the need for further surgery

Post-operative discomfort varies, and your practitioner will discuss pain management with you. Recovery usually involves a compression garment or supportive bra and a period of modified activity. Recovery time varies, and your practitioner will advise when you can return to work and normal activities.

In Australia, cosmetic surgery requires a GP referral, two consultations (one in person with the performing doctor) and a cooling-off period of at least seven days before surgery can be booked. Before proceeding, you may wish to seek a second opinion from an appropriately qualified health practitioner.

FAQ

Can men have liposuction to reduce chest size?

Yes, liposuction is used for fatty chest tissue in men. Where firm glandular tissue is present (gynaecomastia), other techniques may be discussed.

Will breast size change if I gain or lose weight after liposuction?

Yes. Remaining fat cells in the breast can enlarge or shrink with weight change, so breast size may change over time.

Can liposuction make one breast smaller than the other to correct asymmetry?

It may be used to reduce volume on one side where the difference is due to fat. Exact symmetry cannot be guaranteed.

Can fat removed from the breasts be used elsewhere?

Fat transfer usually uses fat from other areas. Our breast fat transfer page explains that procedure, which aims to increase breast size.

Is liposuction an option if I have breast implants?

This requires individual assessment. Tell your practitioner about implants and any previous breast surgery.

If you are unsure whether your breasts are more fatty or glandular, or which approach suits your goals, a consultation with a registered medical practitioner is where this can be assessed.
