Mastectomy: Before Your Surgery

Picture of before and after a mastectomy

What is a mastectomy?

A mastectomy is surgery to remove a breast. There are many ways the surgery can be done. The type of surgery you will have depends on your situation and whether you plan to have reconstructive surgery.

If a mastectomy is done to cure or prevent cancer, the entire breast, including the nipple, is removed. The doctor may also check the nearby lymph nodes during the surgery.

After your surgery, you will probably stay in the hospital overnight. Depending on the type of work you do, you may be able to go back to work or your normal routine in 3 to 6 weeks.

When you find out that you have cancer, you may feel many emotions and may need some help coping. Seek out family, friends, and counsellors for support. Your doctor can guide you to many local resources for support and more information. Call the Canadian Cancer Society (1-888-939-3333) or visit its website at www.cancer.ca for more information.

Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.

How do you prepare for surgery?

Surgery can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for surgery.

Preparing for surgery

Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.
Understand exactly what surgery is planned, along with the risks, benefits, and other options.
If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your surgery. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
Tell your doctor ALL the medicines and natural health products you take. Some may increase the risk of problems during your surgery. Your doctor will tell you if you should stop taking any of them before the surgery and how soon to do it.
Make sure your doctor and the hospital have a copy of your advance care plan. If you don't have one, you may want to prepare one. It lets others know your health care wishes. It's a good thing to have before any type of surgery or procedure.
