Myths about breast cancer

Wearing underwire or tight-fitting bras  – Cancer Australia, Australia’s leading national cancer control agency, states that research does not support the claim that underwire or tight-fitting bras increase a person’s risk of breast cancer. 

Using antiperspirants or deodorants  – Internet rumours have suggested that chemicals in underarm antiperspirants are absorbed through the skin, interfere with lymph circulation, and cause toxins to build up in the breast, eventually leading to breast cancer. There is not enough evidence to show that using antiperspirants or deodorants can increase your risk of developing breast cancer. 

Abortion and spontaneous miscarriage – Cancer Australia states unequivocally that there is no link between termination of pregnancy and an increased risk of breast cancer. This includes both induced abortion and spontaneous miscarriage. 

Breast implants – Several studies have found that silicone breast implants do not increase a person’s risk of developing breast cancer, although silicone breast implants can cause scar tissue to form in the breast. Macro-textured breast implants used in breast reconstruction may be linked to a very rare type of lymphoma called anaplastic large cell lymphoma. These types of implants are currently not available in Australia. 

Stress – The majority of research to date does not show a link between stress and increased risk of breast cancer. However, there have been some conflicting results. More research is needed in this area. 

Bump or knock to the breast – Research has shown a bump or knock to the breast does not cause breast cancer. However, it can draw attention to an existing lump in the breast.
