Breast cancer is surrounded by many myths that can cause confusion and fear. It is crucial to debunk these misconceptions in order to better understand the disease and encourage prevention and screening behaviors. Here is an in-depth analysis of the most common myths and the realities based on scientific evidence.
Myth 1: A mobile lump is not cancer
Reality : The mobility of a lump is not a reliable indicator for determining whether it is cancerous or not. In fact, many breast cancers begin as mobile masses. It is only when they grow and attach themselves to surrounding structures that they become immobile. It is therefore essential to consult a physician for any lump detected, whether mobile or not.
Myth 2: Women with small breasts have a lower risk of developing breast cancer
Reality : Breast size has no connection to the risk of developing breast cancer. What matters is breast density. Dense breasts, which contain more glandular tissue than fat, can increase the risk of cancer and make mammograms more difficult to interpret.
Myth 3: Breastfeeding reduces the risk of breast cancer
Reality: This is true. Breastfeeding, especially if it lasts more than 12 months, can reduce the risk of breast cancer. This is due to the fact that breastfeeding delays the return of regular menstrual cycles, thereby reducing exposure to hormones that may promote the development of cancer..
Myth 4: Taking hormones during menopause causes breast cancer
Reality: This myth is nuanced. Hormone replacement therapy (HRT) may slightly increase the risk of breast cancer, but this depends on the duration and dosage of the treatment. Risks are generally low for short-duration treatments (less than five years) and at low doses.
Myth 5: Only a family history of breast cancer increases the risk
Reality: Although family history increases the risk, the majority of women diagnosed with breast cancer have no cases in their family. Other risk factors include age, breast density, and certain lifestyle habits such as alcohol consumption and lack of exercise..
Myth 6: Deodorants and underwire bras cause breast cancer
Reality: There is no solid scientific evidence to support these claims. Studies have found no link between the use of deodorants, underwire bras and breast cancer4.
Myth 7: Men cannot have breast cancer
Reality: Although rare, breast cancer can also affect men. Approximately 1% of breast cancers occur in men. Symptoms include lumps in the breast, changes to the skin or nipple, and discharge.
Dispelling these misconceptions is essential for a better understanding and prevention of breast cancer. As ST DIGITAL employees, it is important to stay informed and share this knowledge to encourage early screening and preventive behaviours. Together, we can help reduce the impact of this disease.
