Unproven risk factors for breast cancer

Research has shown there is no link between termination of pregnancy and increased risk of breast cancer. This includes both induced abortion and spontaneous miscarriage.

Several studies have found that silicone breast implants do not increase a woman’s risk of developing breast cancer.

Research does not support the claim that underwire or tight-fitting bras increase a woman’s risk of breast cancer.

There has not been enough research to determine whether anti-perspirant deodorant is associated with an increased risk of breast cancer. Further studies are needed.

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.

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.
