The internet offers a wealth of information, but it's easy to get lost in a web of misinformation that causes unnecessary fear. As with any health concern, numerous myths about breast cancer circulate widely. Here are 10 common myths, debunked with facts.
#1. All Breast Lumps Are Cancerous
Myth. No, not all breast lumps are cancerous. Many are benign (non-cancerous), such as cysts or fibroadenomas. However, any new lump should be evaluated by a healthcare provider.
#2. All Breast Cancers Appear as Lumps
Myth. Breast cancer may not always present as a lump. Other signs include:
- Skin changes like redness or thickening
- Nipple retraction (turning inward)
- Dimpling or puckering of the breast skin
- Nipple discharge (especially if bloody)
#3. Family History Is a Risk Factor for All Breast Cancer Patients
Myth. Family history accounts for only 5–10% of all breast cancer cases. Most women diagnosed have no family history of the disease.
#4. Breast Cancer Is Contagious
Myth. Cancer is not contagious. It cannot spread from person to person through touch or proximity. Rare cases of transmission have occurred only through organ or tissue transplants.
#5. There Is Nothing You Can Do to Lower Your Risk
Myth. Lifestyle plays a key role. You can reduce risk by maintaining a healthy weight, exercising regularly, eating a balanced diet, limiting alcohol, and avoiding smoking.
#6. Deodorant Causes Breast Cancer
Myth. There is no clinical evidence that antiperspirants or deodorants cause breast cancer due to aluminum or toxin buildup. Major health organizations have found no link.
#7. Underwire Bras Cause Breast Cancer
Myth. A 2014 study found no scientific evidence linking bras—underwire or otherwise—to breast cancer. Wearing a bra, even at night, does not increase risk.
#8. Mammograms Prevent Breast Cancer
Myth. Mammograms do not prevent cancer. However, they save lives by detecting cancer early when treatment is most effective.
The US Preventive Services Task Force recommends routine screening mammograms starting at age 50 for average-risk women, and at age 40 for high-risk individuals.
#9. Breast Cancer Affects Only Women
Myth. Men can also develop breast cancer, though it's rare—less than 1% of all cases. Men should also be aware of symptoms like lumps or nipple changes.
#10. Mammograms Are Dangerous
Myth. Mammograms use low-dose radiation, similar to other X-rays. The benefits of early detection far outweigh the minimal risks when performed within approved medical guidelines.
