Medically reviewed by Dr Johann Tang, Senior Consultant Radiation Oncologist

Breast cancer is one of the most commonly occurring cancers among women in Singapore, accounting for 29.7% of all cancers diagnosed in females. Due to the prevalence of this condition, there are various mistruths surrounding it. Let our breast cancer doctor, Dr Johann Tang, separate fact from fiction by debunking the common myths surrounding the disease, helping you understand what the genuine risk factors are.

Myth #1: Only Those With A Family History Of Breast Cancer Are Vulnerable

While a family history of breast cancer does increase one’s risk, its absence does not mean you are immune from the disease. In fact, less than 15% of all breast cancer cases are passed on genetically. Therefore, it is recommended to undergo regular mammogram screenings even if nobody in your family has ever been diagnosed with the illness.

Myth #2: Radiation Levels From Mammograms Are Harmful

Mammograms are designed to detect breast cancer, not spread it. While patients are exposed to x-ray radiation during the screening, the effective radiation dose is only about 0.7mSv, which is about the same as what an average person receives from atmospheric radiation in three months.

While mammography remains the best screening tool for breast cancer, please note that it cannot detect all forms of the condition, as specific types of cancer are not readily seen on mammograms.

Moreover, normal breast tissue can hide the cancerous cells, especially if the cancer is small and the patient’s breast tissue is dense. In such circumstances, you may need to undergo an ultrasound or MRI scan for further diagnosis. A breast cancer doctor will assess and advise you accordingly.

Myth #3: Breast Cancer Only Affects Women

While breast cancer is more common in women, the disease can affect both genders since men also have breast tissue. However, breast cancer in men is rare, with only 1% of diagnoses being men. Nevertheless, men should also check themselves periodically by doing a breast self-exam. If you detect a hard lump underneath the nipple and areola, please consult a breast cancer doctor for further examination.

Myth #4: Wearing A Bra Increases The Risk Of Breast Cancer

There is no scientific evidence to demonstrate that wearing a bra of any kind, including an underwire, can cause breast cancer or increase one’s risk.

Myth #5: Getting Breast Implants Increase Your Risk Of Breast Cancer

While breast augmentation can cause scarring on the breast tissue, no evidence suggests the procedure can increase one’s risk of developing breast cancer.

Myth #6: Breast Cancer Is Always A Lump You Can Feel

A normal breast self-examination does not eliminate the possibility of having breast cancer. While a lump is one of the most common symptoms of the disease, not all types of breast cancer produce a lump that you can feel. Furthermore, some lumps may be too small to detect via a self-exam. That is why it is recommended to go for regular mammogram screening, as it remains the most effective way to screen for early breast cancer.

Myth #7: Those With The BRCA Gene Will Get Breast Cancer

Not every person who carries a BRCA-1 or BRCA-2 gene mutation will develop breast or ovarian cancer. However, it does increase one’s risk for these diseases. Those who test positive for either gene mutation have a 45 to 60% chance of getting breast cancer before the age of 70.

Fortunately, various proactive measures are available to reduce one’s risk of developing breast cancer, such as hormone therapy or surgical interventions. If you discover that you possess a BRCA-1 or BRCA-2 gene mutation, please consult a breast cancer doctor to discuss the options that are suitable for you.

Don’t let the misinformation surrounding breast cancer mislead you. Take charge of your health today by performing routine breast self-exams, going for regular mammogram screenings, and reporting anything abnormal to your doctor. Doing so can help with early detection and treatment, thus improving the chances of recovery.
