Breast cancer myths and screening misconceptions

Common misconceptions regarding breast cancer causes and screening methods often lead women to delay essential medical care. Scientific evidence confirms that physical contact, such as touching, squeezing, or breastfeeding, does not cause breast cancer. The disease is primarily driven by genetic, hormonal, environmental, and lifestyle factors, including age, BRCA1/BRCA2 gene mutations, and alcohol consumption.

Regarding screening, several myths can hinder early detection. While family history is a risk factor, over 80% of breast cancer cases occur in women without a family history. Additionally, concerns regarding radiation from mammography are often overstated; the ionizing radiation used in 2D and 3D mammograms is relatively low, and the benefits of early detection generally outweigh the potential risks. Waiting until a physical lump is felt can also delay diagnosis, as screening is designed to find abnormalities before symptoms appear.
