Breast Cancer Myths vs. Facts: What You Need to Know

By Dr. Piyusha Kulshrestha in Cancer Radiation Oncology

Breast cancer is one of the most common cancers worldwide, but despite advancements in awareness and treatment, many myths persist. Misinformation can lead to unnecessary fear, delayed diagnosis, or ineffective prevention strategies. Let’s debunk some of the most common myths about breast cancer and uncover the facts.

Myth 1: Only Women Get Breast Cancer

Fact: While breast cancer is far more common in women, men can also develop the disease.

Though rare, male breast cancer accounts for about 1% of all breast cancer cases. Men should also be aware of symptoms like lumps, nipple discharge, or changes in the skin around the breast.

Myth 2: Every Breast Lump Indicates Cancer

Fact: Not all breast lumps are cancerous.

Many breast lumps are benign (non-cancerous) and could be caused by cysts, fibroadenomas, or hormonal changes. However, any lump should be evaluated by a doctor through mammograms, ultrasounds, or biopsies to rule out cancer.

Myth 3: Breast Cancer Only Affects Older Women

Fact: While the risk of breast cancer increases with age, younger women can develop it too.

Breast cancer can occur in women in their 20s and 30s, though it is more common in women over 40. This is why self-examinations and regular screenings are essential for all women, regardless of age.

Myth 4: Wearing a Bra, Especially an Underwire Bra, Increases Breast Cancer Risk

Fact: No scientific evidence supports a link between wearing bras and breast cancer.

Some myths suggest that underwire bras restrict lymph flow, leading to toxin buildup, but research has debunked this claim. Wearing a bra has no proven link to an increased risk of breast cancer.

Myth 5: If No One in My Family Has Breast Cancer, I Won’t Get It

Fact: Most breast cancer cases occur in women with no family history.

While a family history increases risk, nearly 85% of breast cancer cases occur in women without a family history. Lifestyle factors, hormonal changes, and environmental influences also play a role.

Myth 6: Deodorants and Antiperspirants Cause Breast Cancer

Fact: No scientific studies have confirmed a direct link between deodorants and breast cancer.

Some concerns stem from chemicals like parabens and aluminum, but research has not proven that they contribute to breast cancer development.

Myth 7: A Mammogram Can Cause Breast Cancer or Spread It

Fact: Mammograms do not cause or spread cancer.

Mammograms use low-dose radiation and are essential for early detection. The benefits far outweigh any minimal risk, and regular screenings can save lives by detecting cancer in its early, more treatable stages.

Myth 8: Healthy Eating and Exercise Guarantee Protection from Breast Cancer

Fact: While a healthy lifestyle reduces risk, it does not eliminate it.

Eating a balanced diet, maintaining a healthy weight, and exercising regularly lower the risk of breast cancer, but genetics, age, and hormonal factors still play a role.
