Chemotherapy

Chemotherapy is the use of one or more drugs to destroy cancer cells that may be present in the body. It is often used after surgery for breast cancer to kill any cancer cells that may be left undetected in the breast or lymph nodes or that may have spread to other parts of the body. Chemotherapy can lower the risk of breast cancer coming back. 

Chemotherapy can also be used before surgery to reduce the size of a large tumour so that the surgeon has the best possible chance of removing all the remaining tumour during surgery.

Will I need chemotherapy?

Many women with breast cancer will be referred to a medical oncologist to discuss whether or not chemotherapy is an appropriate treatment for them. Chemotherapy is offered to some women as an additional treatment to surgery, radiotherapy, and/or hormonal therapy.

Oncotype DX

Oncotype DX is a test that can help determine whether or not you may benefit from chemotherapy treatment. This specialised test analyses 21 genes within your tumour to make a prediction about the likelihood of your breast cancer recurring. If the test shows you have a high risk of recurrence, chemotherapy may be recommended for you. If the test shows you have a low risk of recurrence, you may be able to avoid chemotherapy.

The test is not currently covered by Medicare and is quite expensive at $4000.

For further information about Oncotype DX testing, visit the Breast cancer pathology page or talk to your surgeon or medical oncologist.

How does chemotherapy work?

Chemotherapy attacks the fast-growing cells in your body, including cancer cells. There are many different types of chemotherapy and not all of them will suit you. Your medical oncologist will discuss with you the best options for you. Sometimes two treatments might be considered equally effective and you will be asked to decide which one to have.

Some questions to consider in making this decision include:

  • What are the potential side effects of each treatment?
  • Is the treatment given intravenously or orally?
  • How long is the course of each treatment?
  • How will the treatment fit in with your lifestyle and personal circumstances?

Chemotherapy is usually administered intravenously (by needle into a vein in the arm or hand), so drinking plenty of fluids, relaxing and keeping your hands and arms warm can help with finding your veins. Some chemotherapy drugs are given in tablet form.

What are the side effects?

Unfortunately chemotherapy attacks healthy cells as well as cancer cells. This can result in unwanted side effects, such as fatigue, nausea and hair loss. Your doctor or nurse can give you information on ways to manage any side effects you may experience.

It's important to discuss your side effects with a member of your medical team, especially if they are affecting your daily life. It may be possible for your oncologist to change your chemotherapy drug to one that has fewer side effects. Chemotherapy drugs all work a little differently, so have different side effects. Not all women will suffer side effects from chemotherapy - this doesn't mean the drugs aren't working.

"Discuss every side effect to your treatment with your oncologist. Treatments are improving all the time and most side effects can be managed to minimise your discomfort." --Julia

Hair loss

Because it's visible to others, hair loss (alopecia) can be one of the more distressing side effects of chemotherapy. The hair loss page contains information and strategies on how to deal with hair loss.

Nausea

Nausea and vomiting are common side effects of chemotherapy. You may be given anti-nausea medication before your chemotherapy to take home with you, just in case.  If you have nausea and/or vomiting that lasts for more than 24 hours, let your doctor know. It’s easy to become dehydrated quickly, and your doctor can help with this.

Mouth care

During chemotherapy, women sometimes experience changes in taste and mouth ulcers. Some have found that Rinsing your mouth regularly with bicarbonate of soda can help to prevent ulcers, even before you begin chemotherapy. If they do develop, using a child’s toothbrush is gentler on the gums. A supply of soft mints can help get rid of the metallic taste, and chilled blended drinks can help you with nutrition and soothe a sore mouth.

Early menopause

In some women chemotherapy can reduce the level of oestrogen and cause periods to stop temporarily or altogether. This is called early menopause. You may experience some of the symptoms of menopause, such as hot flushes and night sweats. BCNA’s Menopause and Breast Cancer booklet provides practical tips to help manage the symptoms of menopause. Download a copy from our fact sheets and booklets page, or order a free copy from our online shop.

Bone health

Chemotherapy reduces the level of oestrogen in your body, which can reduce your bone density and increase your risk of bone fractures. The bone health page provides more information on how to improve bone health.

Nail health

Nail changes are a common side effect of some chemotherapy treatments. The nail health page provides more information on the changes that may occur to your nails, and what you can do help prevent or manage nail changes.

Fatigue

Fatigue is very common during chemotherapy. Women describe it as being quite different to normal tiredness. Light exercise can boost your energy levels.

The page on fatigue contains more information on how to manage fatigue, and the section on physical wellbeing has more information about how exercise can boost your energy levels.

'Chemo brain'

A less common side effect of chemotherapy is a condition many people refer to as 'chemo brain' or 'chemo fog'. It is described as feeling vague. Some women say they have trouble remembering things and find they aren't as organised as they used to be. The page on Chemo brain has some suggestions on how to manage the effects.

Loss of fertility

The impact of chemotherapy may reduce a woman’s fertility and chance of having children in the future. There are a number of factors which contribute to this issue, including a woman’s age, and the type of treatment she has and how it affects her ovaries. There are a number of methods for preserving fertility. BCNA’s webpage for young women provides more information on this issue.
