What is breast cancer?
Breast cancer is a tumour that starts growing in the breast (usually in the inner lining of the milk ducts), and can go on to spread to other parts of the body. Breast cancer occurs in a number of different types and stages, which are broadly grouped as either:
- Early breast cancer (eBC): As the name suggests, this disease is in the early stages; which means it has not spread beyond the original tumour site.
- Metastatic breast cancer (mBC): Also known as advanced breast cancer, this is where the disease has spread from the original site to other parts of the body.
Another important factor in the diagnosis of your breast cancer is the HER2 status. HER2 is a type of human growth factor that occurs normally in some of our cells. In HER2 positive breast cancer this growth factor is found in higher levels than normal and causes the cancer to grow faster. HER2-positive early or metastatic breast cancer is a particularly aggressive form, as it spreads quicker and is more likely to return.
Diagnosis and testing
Breast cancer is often detected when a woman notices a lump in her breast or during a routine mammogram. After that, a doctor will take a biopsy (small tissue sample) from the tumour and send it off for analysis. The results of these tests should give you the type, stage (describes how much the cancer has spread, a low stage is local, Stage 1; a high stage is wide spread, stage 4) and HER2 status of your cancer.
Treatment for breast cancer
Most people with breast cancer will undergo surgery at some point to try and remove the tumour. Dependent on the type, stage and HER2 status of the cancer, chemotherapy and other medications known as biological therapy can also be given.
Chemotherapy
Chemotherapy is a treatment with one or a combination of anti cancer medicines that aim to destroy or control cancer cell growth. Chemotherapy is usually given intravenously i.e. through a vein; however, if you have metastatic breast cancer your doctor may offer you an oral option that you can take at home.
Xeloda is taken orally in tablet form and is fully funded for metastatic breast cancer patients who are having difficulty with standard chemotherapy. And because Xeloda can be taken at home, it allows patients more independence to live their lives, as they spend less time and money travelling to cancer centres to receive treatment.

Biologic therapies
Biological therapy includes anticancer treatments known as monoclonal antibodies. Monoclonal antibodies are derived from the body’s natural immune defences and are designed to specifically target only cancer cells and leave normal cells alone. These therapies are generally well tolerated and do not have the same side effects as chemotherapy, such as hair loss, severe nausea and vomiting and increased risk of infection.
Herceptin is a biological therapy also know as a monoclonal antibody that specifically targets HER2 proteins on breast cancer cells and is an effective treatment for women with HER2-positive breast cancer. If your breast cancer is HER2 positive your specialist may recommend a full 1-year course of Herceptin. A full 1-year course of Herceptin is government funded and is proven in its ability to help fight HER2-positive breast cancer and gives you the best chance of beating it long term.

Avastin is a biologic therapy (also known as a targeted agent), which has been proven to increase survival times for people with metastatic breast cancer. Avastin is not funded, and patients must pay for this treatment themselves. Your Oncologist will be able to tell you what it may cost to be treated with Avastin.

Managing the side effects of chemotherapy
One of the common side effects of chemotherapy is a low white blood cell count. White blood cells fight infection so when these are low you are at increased risk of developing an infection, which can be life threatening. This condition is called neutropenia. Neulastim is used following chemotherapy to increase the number of white blood cells. This can reduce your chance of developing infections that might require treatment with antibiotics and/or hospital stays. These complications of chemotherapy can mean delays in your treatment and affect how well your treatment works. Neulastim may also help to keep your chemotherapy treatment on schedule.
