Complementary and Alternative Therapies

The Sydney Cancer Centre supports therapies that have been proven to be safe and effective in scientific studies.

There is currently wide interest in complementary and alternative cancer therapies, and this is not surprising since conventional treatments are sometimes seen as being complicated, painful or even having significant side effects.  Furthermore cure can often not be guaranteed.

Here at the Sydney Cancer Centre we offer evidence-based integrated cancer care, that is we use treatments known to be effective.  At the same time we are conducting numerous trials of new therapies, but always in carefully planned clinical trials using reliable scientific methods.

Although cure rates are improving we do not believe we have all of the answers so we remain open minded about new treatments for and approaches to cancer.

It is important however that patients are fully informed about new therapies, especially when they are unconventional and of unproven benefit.

Complementary & Alternative Therapies - Understanding the Differences
The terms "complementary" and "alternative" are often used interchangeably, when in fact they mean two different things.  This section will help you understand what each of the terms means.

Complementary therapies
The term "complementary cancer therapies" refers to therapies that are used alongside conventional cancer treatments (surgery, radiotherapy, chemotherapy, hormone therapy and immunotherapy).

Complementary therapies do not claim to cure cancer, but may help people feel as well as possible and enhance their quality of life.

Examples of complementary therapies include counselling, relaxation and meditation, massage, acupuncture, yoga, aromatherapy, and music and art therapy.

Complementary therapies are generally unlikely to do any harm.  However it is important that you talk with your Doctor before trying them to make sure they are suitable for your condition and will not impact your cancer treatment in any way.

Alternative therapies
The term "alternative cancer therapies" refers to clinically unproven treatments that are used instead of conventional cancer treatments.

Alternative therapies sometimes claim they provide a "miracle cure" but some may in fact have harmful side effects or potentially interfere with your treatment.  Unlike conventional treatments, which have usually been proven to be effective through extensive clinical trials, most alternative therapies have not been scientifically tested and so proof of their effectiveness is usually lacking.  Their side effects are also not always known.

Examples of alternative therapies include special diets, shark cartilage, laetrile, spiritual healing, ozone therapy, herbal treatments, taking large doses of vitamin supplements, coffee enemas and microwave therapy.

If you are thinking about trying an alternative therapy it is very important that you talk with your Doctor so that you have all the information you need before making a decision.  Your Doctor will be able to help you understand any potential side effects and the impact it will have on your cancer treatment.

Questions to ask when considering complementary & alternative therapies
Before making any decisions on complementary and alternative therapies, be sure that you have all the information you need to make an informed decision.  As mentioned it is important that you talk with your Doctor about any therapies that you are considering.  Gather as much information as possible from credible sources and then ask for your Doctor's professional opinion as to whether or not the therapy is safe and medically sound, and talk with him or her about how it might be safely integrated into your current treatment plan.  Listed below are some questions you may like to get the answers to:

  1. What are the benefits claimed about this therapy?
  2. What are the risks and side effects associated with this therapy?
  3. Do the known benefits outweigh the risks and side effects?
  4. Will the therapy interfere with conventional treatment? eg. lessen the effectiveness, or cause harm when combined
  5. Has the therapy been tested in clinical trials and do the results confirm any claims about its effectiveness?  Have the results been published in any recognised medical journals and are they available for me to read?
  6. How long should I have the therapy for and how will I know if it is working?
  7. What are the practitioner's qualifications?  Are they a member of a professional association?
  8. What is the practitioner's experience of treating people with my type of cancer?
  9. How much does the therapy cost and can I afford it?  Is it covered by Medicare/my private health insurance?
  10. If the therapy involves taking some kind of product, has it been approved by the Australian Therapeutic Goods Administration and for what purposes?

Complementary therapies that can help
The following therapies have been shown to be helpful in dealing with the side effects of cancer treatment in some clinical trials:

  • psychotherapy, counselling, relaxation, support groups: help reduce stress
  • meditation: improves sleep and reduces stress
  • yoga: improves sleep and reduces stress
  • massage: helps reduce pain and fatigue, and improves sleep
  • tai chi: relieves pain, improves flexibility and strength, and reduces stress
  • reflexology: reduces anxiety
  • spiritual practices: help reduce stress
  • acupuncture: reduces nausea, vomiting and fatigue from chemotherapy and radiotherapy
  • aromatherapy: improves sleep
  • art and music therapy: provide distraction from pain and aid relaxation.

Healthy habits
Eating more vegetables, fruits and legumes, together with regular physical activity has many benefits. These healthy habits may help slow the development of many cancers and may also help reduce the risk of cancer recurring or secondary cancers.
Exercise may also boost your energy levels, decrease fatigue, relieve stress, and lower anxiety and depression.

Advice on nutrition
It’s common for people with cancer to wonder if eating special food will help cure the cancer. There are no special foods, diets or vitamin supplements that have been scientifically proven to cure cancer or to stop it from coming back. However, nutrition is one of the factors that can protect against cancer and eating nutritious food can help to keep you as well as possible during treatment.

Many alternative dietary treatments, particularly those that cut out food groups such as meat or dairy products, may not provide enough energy (kilojoules) and protein. This can cause unwanted weight loss, tiredness and decrease your immune function.

If you are considering making a dramatic change to your diet, talk to your dietitian or doctor first. Your dietitian can also give you advice on food to eat during and after cancer treatment so you stay as well as possible.
