What are some of the unproven risk factors (myths) associated with breast cancer?



Using antiperspirant deodorants causes breast cancer.

There is no evidence.

Wearing a tight bra causes breast cancer.

There is no evidence.

A bump or knock to the breast causes breast cancer.

There is no evidence. However, it can draw attention to an existing lump.

Stress causes breast cancer.

There is no evidence.

Only your mother's family history of breast cancer can affect your risk of breast cancer.

A history of breast cancer in either your mother's OR your father's family will influence your risk.

If breast cancer doesn't run in my family, then I won't get it.

Every woman has some risk of breast cancer. 9 out of 10 women who get breast cancer do not have a family history of the disease.

Having a mammogram will prevent breast cancer.

Mammograms (breast X-rays) cannot prevent breast cancer. Mammograms can detect breast cancer early, which increases your chances of successful treatment.

Regular self examinations are the best way to detect breast cancer.

A mammogram is the most reliable way to detect breast cancer at an early stage, however be aware of changes in your breasts. Ask your GP about breast health at your next check-up.

Breast compression during a mammogram spreads breast cancer. There is no evidence.
Women need a thyroid shield when having a mammogram.  BreastScreen WA does not have, or need, "thyroid guards" as radiation risk to the thyroid from a mammogram is negligible, as the X-ray beam is narrowly focussed to only target the breast area.
