Why should I check my breasts regularly?
Checking your breasts regularly is the best way to learn what your breasts look and feel like, so you can learn what is normal for you. By checking your breasts often, you will be able to notice changes as soon as they happen.
Finding breast cancer early provides the best chance of surviving the disease. It gives you the most options for treatment. If you notice any changes in your breasts, see your doctor as soon as possible.
It’s important to remember that not all lumps are dangerous, and 9 out of 10 changes are not related to breast cancer. But it is important to see your doctor to be sure.
How do I do a breast self-exam?
Based on current research, you don’t need to use a special technique to check your breasts. Everyday activities like getting dressed or having a shower are an opportunity to get to know the normal look and feel of your breasts and the area around them.
Take time regularly to look at and feel your breasts, nipples, armpits, the area under your breasts, and the area above your breasts up to your collarbone. You should try to notice the colour, texture and shape of your breasts, and especially pay attention to any new lumpiness.
You should also be aware of any changes to your nipples, including any discharge that comes out without squeezing. Lumps or other changes under your arms and under or over your breasts can also be signs of breast cancer that you should discuss with your doctor. The development of breast cancer is not normally painful, so speak to your doctor about anything unusual that you notice.
What should I look out for?
You should look out for any changes in your nipples, breasts or the areas around them. These could be:
- new lumps or thickening of your breasts or the area under your arm, especially any changes noticed only on one side
- a change in the size or shape of your breasts
- a change in the colour of your breasts such as redness or a rash
- dimpling of the skin on your breasts or the area around them — like the texture of the skin of an orange
- crusting, redness or an ulcer on the nipple or the area around it
- inversion of your nipple so it points inward rather than outward
- a nipple discharge that comes out without your squeezing
- a pain that doesn’t go away
How often should I get a mammogram?
If you are a female aged 50–74 years, you should have screening mammograms every 2 years. If you are a female aged 40–49 years or 75 years and older, you are also eligible for free screening mammograms, although the risk of developing breast cancer in this age range is slightly lower.
Mammograms can detect small lumps in females with no symptoms who would otherwise not know they had breast cancer. It is important to remember that self-examinations should not replace routine screening mammograms. The 2 together are the best way to detect breast cancer early.
Females who are at higher risk of developing breast cancer may need to have screening mammograms more frequently or take other measures to decrease their risk. You can find out more about your risk of developing breast cancer by using the free online iPrevent service provided by the Peter MacCallum Cancer Centre.
When should I see my doctor?
If you notice any changes in your breasts or the areas around them, you should see your doctor as soon as possible.
Everyone’s breasts change as they get older, especially during puberty, pregnancy, breastfeeding and menopause, so sometimes it can be hard to know if a change is normal or if it is a sign of cancer. By discussing all changes with your doctor, you can be sure you are keeping yourself as safe as possible from breast cancer.
If you are male, you can also develop breast cancer and should see a doctor right away if you discover anything unusual.
If members of your family have recently been diagnosed with the disease, you should speak to your doctor about your risk of developing the disease. Your doctor will help you decide if you should attend a screening mammogram more often and may recommend additional ways to reduce your breast cancer risk.
How is breast cancer diagnosed?
If your doctor is concerned that a change in your breasts might indicate cancer, they will recommend you have some tests. These could include:
- mammogram — an x-ray is used to investigate changes that are too small to be felt during a physical examination
- ultrasound — sound waves are used to create an image of the inside of your breast
- biopsy — a small piece of your breast tissue is removed by a doctor and checked under a microscope for signs of cancer
If these tests indicate you have breast cancer, your doctor may recommend other scans such as a CT scan or MRI scan to see if the cancer has spread to other parts of your body. They may also suggest you see an oncologist who is a cancer specialist doctor.
Your oncologist will work with you to assess the size and severity of your breast cancer in a process called staging, to build a treatment plan personalised for you. They may recommend surgery to remove the cancer, together with some or all your breast. Alternatively — or in addition — they may recommend you have chemotherapy, radiotherapy or hormone therapy.
Undergoing tests for breast cancer can be worrying for you and your family and some people feel reluctant to turn to their doctor because of this. It can be helpful to remember that early diagnosis of breast cancer increases your chances of survival and gives you the greatest number of options for treatment.
