9 Myths Surrounding Breast Cancer

Medically reviewed by Dr. Tan Chuan Chien, Consultant General Surgeon (Breast & Thyroid Surgery)

Breast cancer is one of the most common cancers worldwide, particularly among women, but its prevalence has resulted in the spread of numerous myths. These misconceptions can cause unnecessary fear, prevent early detection, or lead to incorrect assumptions about the disease. In this article, we will investigate and dispel some of the most common myths about breast cancer, allowing you to make more informed decisions about prevention, diagnosis, and treatment.

Myth 1: Only Women Get Breast Cancer

Fact: While breast cancer is far more common in women, men can also develop the disease. Male breast cancer accounts for less than 1% of all breast cancer cases, but the risk remains because men, like women, have breast tissue that can develop cancerous cells. Men must be aware of breast cancer symptoms such as lumps, changes in nipple appearance, or discharge, and seek medical attention if they appear.

Myth 2: Finding a Lump in Your Breast Means You Have Cancer

Fact: Not every lump is cancerous. Many breast lumps are benign and caused by non-cancerous conditions such as cysts, fibroadenomas, or infections. However, all lumps should be checked by a medical professional to rule out cancer. A thorough examination, including a mammogram or biopsy, is required to determine whether a lump is cancerous or benign.

Myth 3: Wearing Underwire Bras Increases Your Risk of Breast Cancer

Fact: This is a long-standing myth that lacks scientific support. Some believe that underwire bras limit lymphatic drainage, resulting in toxin buildup in breast tissue, but this theory has been refuted by numerous studies. The bra you wear has no effect on your risk of developing breast cancer. Breast cancer risk factors are more closely related to genetics, age, hormone levels, and lifestyle.

Myth 4: Breast Implants Increase Your Risk of Breast Cancer

Fact: There is no clear evidence that having breast implants increases the risk of breast cancer. However, a rare form of cancer called breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) has been associated with certain types of implants, particularly textured ones. Women with implants need to continue regular breast cancer screenings and be aware of any changes in their breasts.

Myth 5: Breast cancer is always hereditary

Fact: While having a family history of breast cancer can increase your risk, however, the majority of breast cancer cases are not caused by inherited genetic mutations. Only about 5% to 10% of all breast cancer cases are linked to specific gene mutations, such as BRCA1 or BRCA2. These mutations can significantly raise a person’s risk, but many breast cancer cases arise in individuals with no family history of the disease.

Myth 6: Mammograms Can Cause Breast Cancer

Fact: The small amount of radiation used in mammograms is highly unlikely to cause breast cancer. The benefits of regular mammograms far outweigh the risks, as these screenings can detect cancer at an early stage when it is most treatable. For most women, annual mammograms starting at age 40 (or earlier if you have a high risk) are recommended for early detection.

Myth 7: Breast Cancer Always Requires a Mastectomy

Fact: Not all breast cancer treatments involve removing the entire breast. Mastectomy (the removal of the breast) is one option, but many women can be treated with a lumpectomy, where only the tumour and some surrounding tissue are removed. Radiation therapy, chemotherapy, targeted therapies, and hormone therapies are also available, depending on the type and stage of cancer.

Myth 8: You Can’t Get Breast Cancer if You Lead a Healthy Lifestyle

Fact: While living a healthy lifestyle, including exercising regularly, eating a balanced diet, and avoiding smoking and excessive alcohol, can lower your risk of breast cancer, however, it does not eliminate it. Breast cancer can still occur due to genetic factors, age, and other uncontrollable variables. A healthy lifestyle helps but is not a guarantee against breast cancer.

Myth 9: Breastfeeding Reduces Your Risk of Breast Cancer

Fact: While research shows that breastfeeding can reduce the risk of developing breast cancer, especially if done for an extended period, it is not a guarantee of prevention.

Conclusion

Breast cancer is a complex disease, and knowing the facts is necessary for prevention, early detection, and effective treatment. Misconceptions, like those covered in this article, can lead to confusion, fear, and even delays in seeking appropriate medical care. By debunking these myths, we hope to inspire people to stay informed, prioritise regular screenings, and seek accurate advice from healthcare professionals.
