From family history to deodorants and biopsies, several myths about breast cancer continue to circulate. Here’s what medical authorities actually say.
Breast cancer remains surrounded by misconceptions some of which can create unnecessary fear, while others may lead people to overlook important warning signs. As Breast Cancer Awareness Month begins, separating fact from fiction is an important part of understanding the disease.
Myth 1: “If breast cancer doesn’t run in my family, I’m safe.”
Fact: Family history can increase the risk, but having no family history does not mean someone cannot develop breast cancer. According to the World Health Organization (WHO), around 80% of breast cancers occur in women who have no specific risk factors other than sex and age.
Myth 2: “Deodorants and antiperspirants cause breast cancer.”
Fact: This widely circulated claim has not been supported by scientific evidence. According to the US National Cancer Institute (NCI), studies have found no evidence linking the use of deodorants or antiperspirants with the development of breast cancer.
Myth 3: “A biopsy can make cancer spread.”
Fact: A biopsy is used to examine tissue and help establish a diagnosis. According to the NCI, the chance of cancer spreading as a result of a biopsy or surgery is extremely low, and standard medical procedures are designed to minimise this risk.
Myth 4: “If there’s no lump, there’s no breast cancer.”
Fact: A lump is not the only warning sign and some people may have no symptoms at all. According to the Centers for Disease Control and Prevention (CDC), possible signs include changes in breast size or shape, skin changes, nipple changes, unusual discharge and pain.
Myth 5: “Breast cancer only affects older women.”
Fact: Risk generally increases with age, but breast cancer can occur at any age after puberty. According to the WHO, breast cancer occurs in women at any age after puberty, with rates increasing later in life.
The takeaway is simple: myths should not determine how people understand their health. Knowing the established risk factors, recognising unusual breast changes and discussing concerns with a healthcare professional can help people make informed decisions about screening and care.
