Bilateral Mastectomy

Removing both breasts lowers one risk sharply. Whether that helps you depends on why you are considering it.

In BRCA carriers, bilateral prophylactic mastectomy reduced breast cancer risk by about 90 percent. For a healthy breast removed alongside a cancer, a Cochrane review found too little evidence of a survival gain.

Three reasons for a bilateral mastectomy

The reason shapes everything else. Women come to this operation by one of three routes.

• Cancer found in both breasts at once.
• Cancer in one breast, with a choice to remove the healthy one too.
• No cancer, but a BRCA mutation or another high inherited risk.

When cancer is found in both breasts at the same time, removing both is treatment, and the decision follows the same rules as any mastectomy for cancer. When cancer is in one breast only, removing the healthy breast as well is a choice called contralateral prophylactic mastectomy, and its value depends heavily on your inherited risk, your age and your own priorities, since for most women without a high-risk gene the chance of a new cancer in the other breast is low. When there is no cancer at all but a BRCA1 or BRCA2 mutation or a similar high-risk finding, a bilateral risk-reducing mastectomy is preventive surgery, planned without any time pressure, and many women combine it with reconstruction at the same sitting. Each of these paths deserves its own conversation with a breast surgeon and, for the second and third, with a genetic counselor, and each path changes what the operation can and cannot do for you.

How high inherited risk really is

A prospective study of nearly 10,000 women carrying BRCA1 or BRCA2 mutations, published in JAMA in 2017, measured the risk directly.

Inherited risk is the deciding number.

Risk rose with the number of close relatives affected.

What removing both breasts achieves

For BRCA carriers without cancer, the benefit is large.

That is a reduction of roughly 90 percent, rising to 95 percent in women who had also had their ovaries removed.

Risk falls sharply. It does not reach zero.

For a healthy breast removed alongside a cancer, the picture changes. A Cochrane review of 61 observational studies and more than 15,000 women found that this lowers the chance of cancer in the other breast, but found too little evidence that it helps women live longer, because the main threat to life remains the cancer already diagnosed. The same review found that most women were satisfied with their decision and worried less about cancer, while satisfaction with body image and sexual feelings fell for some. Unplanned further operations ranged from 4 percent in women without reconstruction to 64 percent in some series with reconstruction, which is why the reconstruction choice weighs as much as the mastectomy itself and deserves the same care when you plan the operation with your surgeon and decide between implants, your own tissue or a flat closure. Bias matters. The reviewers noted that younger and healthier women were more likely to choose the extra surgery, which can make its survival figures look better than the operation deserves.

Options other than surgery

Not every high-risk woman chooses a mastectomy, and each alternative is a real option.

Types of mastectomy and reconstruction

Skin and nipple can stay in many cases.

1. Total mastectomy. Breast tissue, nipple and much of the skin removed.
2. Skin-sparing mastectomy. The skin envelope kept for reconstruction.
3. Nipple-sparing mastectomy. Skin and nipple kept when no cancer lies near the nipple.

Reconstruction can follow in the same operation, with implants or with your own tissue from the abdomen or back, or later once other treatment is over, and some women choose to stay flat with a smooth chest wall closure. Our breast reconstruction page covers those options in detail.

Getting ready

Complications and how they are managed

Two breasts mean two wounds. A national database study of 9,319 women found higher odds of complications when one breast was removed for cancer and the other prophylactically than when both were removed preventively, a difference linked to the lymph node surgery on the cancer side. In a series of 434 nipple-sparing mastectomies with implant reconstruction, 11 percent needed a further operation for a complication within 30 days, with no difference between one breast and two.

The recovery

Arm exercises start the next day.

Drains stay for one to two weeks, and you sleep on your back with a supportive bra or binder. Light daily activity resumes within days, desk work in two to four weeks, and lifting and driving wait for drains to come out and the surgeon to clear them, longer after tissue reconstruction. The emotional recovery runs on its own timetable. Many women feel relief alongside grief for what was lost, and talking with a counselor or with others who have been through it helps. Looking at the chest for the first time is easier with a nurse or a partner present, and the team plans that moment rather than leaving it to chance at the first dressing change. Shoulder stiffness is common in the first weeks, so the physiotherapist teaches a short set of arm lifts and wall climbs to do several times a day until full movement returns, which for most women takes four to six weeks.

How long to stay in Istanbul

Plan for two weeks with reconstruction.

Published mastectomy packages in Istanbul list two days in hospital and a seven-day stay in Turkey. With immediate implant reconstruction on both sides the stay runs to ten to fourteen days, which leaves time for the drains to come out, the wounds to be checked by the surgeon and the first arm exercises to be learned before flying, and tissue reconstruction needs longer still.

What decides the cost

One or both sides, the type of mastectomy, reconstruction and its method, lymph node surgery, nights in hospital and genetic testing set most of the figure.

Published packages list the surgeon consultation, preoperative tests, general anesthesia, the mastectomy, hospital stay, follow-up examinations and airport transfers, and some add sentinel node examination, a private room or an implant. Hotel nights often sit outside them.

A quote you can compare names both sides, the reconstruction and the stay, and that figure comes only from a breast surgeon reading your imaging and genetic results.

Arranging the trip

A first WhatsApp message reaches a coordinator who stays with you through surgery and after you fly home. You can ask for a female surgeon in that first message. English, Arabic, French, Russian, Serbian, Romanian and Spanish are spoken, with an interpreter for other languages, a companion sleeps in your room on the companion bed, and the international office books a hotel, sends the visa invitation letter ten days before travel and arranges transfers. Halal, vegetarian and diabetic meals and a prayer room are available.

Once you are back home

After a preventive mastectomy, routine screening of the chest is not needed for most women, though any new lump is checked. After cancer, follow-up continues with your oncologist, and BRCA carriers plan for ovarian risk with a gynecologist.

Fever, spreading redness, a wound that opens, a swollen tense breast, or a darkening of the nipple or skin. Each needs a doctor the same day.
