Dr Pieter Swart

A modified radical mastectomy (or MRM) is a surgery done for breast cancer. To remove the cancerous cells from the breast tissue a modified radical mastectomy is done by removing the breast, breast tissue, areola, nipple and most of the lymph nodes under the arm.

​

Why would I need surgery?

​

A mastectomy might be advised when treating breast cancer, either alone or in conjunction with other cancer treatments such as chemotherapy or radiation therapy. The goal of the surgery is to remove the entire tumor, or as much of it as possible, to prevent the spread of the cancer. Traditionally a mastectomy involved the removal of all the breast tissue as well as the chest muscles, which commonly leaves a hollow in the chest. With a modified radical mastectomy the chest muscle is kept in place making it a less extensive surgery than a radical mastectomy, leaving a more aesthetically pleasing result.

​

What does the surgery involve?

​

You will be under general anaesthesia as your surgeon makes a single incision across one side of the chest. The skin is then pulled back so that your surgeon can remove the entire breast tissue. This includes the nipple and areola, some or all of the lymph nodes, the lining over the chest muscles and some or all of the overlying skin. Dr Swart will also preserve as much of the skin as possible so that if you choose to have a breast reconstruction surgery later, this may be done.

​

What can I expect after my surgery?

​

After waking from anaesthesia you can expect some pain, tenderness and numbness in the chest area and your upper arm. You will stay in hospital for observation for a few days and your pain will be managed with medication. During this time you will have a drain placed in your incision to remove any excess fluids. This drain may need to stay in place for the next 2 weeks. Before being discharged you will be instructed on how to care for your wounds and how best to exercise your arm for recovery. Dr Swart will advise you on follow up in his rooms for consultation following surgery and discharge from hospital.
