What is breast cancer?

Breast cancer is a harmful growth that starts in the glandular tissue of your breast.

Lymph nodes (glands) are small structures which lie along lymph vessels present throughout your body. They help your body deal with infections, but they also become involved in the spread of some cancers.

What is an axillary node clearance?

Axillary node clearance is a procedure to remove all the lymph nodes from the affected armpit.

What are the benefits?

Some lymph nodes in your armpit may appear normal but contain cancer cells. Removing all of the lymph nodes in the armpit gives the best chance of clearing the cancer cells from this area.

The lymph nodes that your surgeon removes will be examined under a microscope to help decide on any further treatment.

Surgery will also help reduce the chance of the cancer cells spreading to other parts of the body.

Are there any alternatives?

Sometimes radiotherapy can be used to treat the lymph nodes in your armpit, instead of removing them.

Your breast-care team may not recommend this procedure, particularly if only a small number of cancer cells are found in the lymph nodes in your armpit.

What does the procedure involve?

The procedure is performed under a general anaesthetic and takes about 60 to 90 minutes. It may take a little longer if you have breast surgery at the same time.

Your surgeon will make a cut in your armpit. If you are having a procedure on your breast at the same time, your surgeon may be able to use the same cut.

Your surgeon will remove some or all of the nodes and surrounding fatty tissue in your armpit.

They will close the cut with stitches, sticky strips, clips or glue.

All of the lymph nodes and any breast tissue that your surgeon removed will be examined under a microscope. Your breast-care team will know the results 2 to 4 weeks later.

What happens after the procedure?

Regular exercise should help you to return to normal activities as soon as possible. Before you start exercising, ask the breast-care team or your GP for advice.

The breast-care team will arrange an appointment after the surgery. The lymph nodes and breast tissue that your surgeon removed will have been examined under a microscope. Your breast-care team will tell you the results and discuss with you any treatment or follow-up care you need.
