Most men and women think that breast cancer is only for women and those who have a family history. But it is not true medically. These myths result in ignoring the signs and symptoms and delaying a cancer screening.

But the facts say the opposite. Breast cancer can happen in anyone at any age. Diagnosing breast cancer at early stages saves lives and improves life quality. Everyone should know the myths and evidence-based, expert opinions and spread awareness about breast cancer causes, occurrence, prevalence, cure, and supportive care. When you know the fact, it helps you make the right choice and decision for better living.

Below are the 18 common myths and biases about breast cancer:

  1. Myth 1: Most women who develop breast cancer have a family history or genetic mutation.

Fact: Only 10 to 5 percent of breast cancers are caused by hereditary mutations in genes such as BRCA1 (breast cancer 1), BRCA2 (breast cancer 2), and PALB2 (partner and localizer of BRCA2). Having a family member or close relative with breast cancer increases the risk, most women who have had breast cancer have no family history or inherited gene changes.

  1. Myth 2: Breast cancer occurs only in women.

Fact: It is common to think that it happens only in women. Although less common, men also develop breast cancer. They often notice it during self-exam, finding a lump or unusual growth. Any new growths or lumps should be checked by a doctor.

  1. Myth 3: Breast cancer affects only the elderly or older women.

Fact: The risk of breast cancer rises with age, with the majority of diagnoses happening in women over 50. In fact, cases among younger women have been rising in recent years.

  1. Myth 4: Breast implants increase your cancer risk.

Fact: Studies show that breast implants do not cause breast cancer. However, they sometimes make it harder to detect tumors on mammograms, so women with implants should inform their doctor before screening.

  1. Myth 5: Mammograms are not effective.

Fact: Mammograms save lives by screening for breast cancer at an early stage. When detected early, breast cancer is nearly completely treatable, often with fewer and less invasive measures and operations.

  1. Myth 6: A lump is the only sign of breast cancer.

Fact: Lumps are the most common sign of breast cancer, but other breast cancer symptoms are breast swelling, skin dimpling, discharge from the nipple, a red rash, and more.

  1. Myth 7: Eating sugar makes the cancer grow faster.

Fact: There are no studies that suggest that cutting out sugar prevents cancer. However, a high-sugar diet (mainly processed and refined sugar) leads to obesity, inflammation, and insulin resistance, all of which are risk factors for breast cancer and poor outcomes following diagnosis.

  1. Myth 8: Mammograms do not help you live longer.

Fact: A few studies show that mammograms lower life expectancy. But others say that mammograms help in early detection of breast cancer and guide in early treatment that saves lives. When it is diagnosed at early stages, it can save lives when therapy is effective. However, mammograms cannot be used incorrectly. While they might help with early detection, cancer is still possible between follow-ups.

  1. Myth 9: Using an underwire bra puts women at a higher risk of developing breast cancer.

Fact: There is no scientific evidence that underwire bras cause breast cancer. Your chances of getting breast cancer are not affected by the type of bra you wear or by the occurrence of breast cancer type.

  1. Myth 10: Breast cancer is caused by antiperspirants or deodorants.

Fact: Research shows that deodorants and antiperspirants do not cause breast cancer or increase your cancer risk. This is believed to be so because of the compounds found in various antiperspirants that are carcinogenic. However, no evidence shows a link between breast cancer and aluminum-based products.

  1. Myth 11: Receiving a breast cancer diagnosis carries a death sentence.

Fact: Although receiving a breast cancer diagnosis might be scary, outcomes have improved dramatically. Thanks to early detection, therapy, and supportive care. Mainly, when the cancer is found and treated early, many people with breast cancer go on to enjoy full and healthy lives.

  1. Myth 12: A breast injury causes breast cancer.

Fact: There is no proof that injury leads to breast cancer. An injury might cause pain, swelling, or bruising, but it does not result in cancerous cell growth.

  1. Myth 13: Women with larger breasts have a higher chance of breast cancer.

Fact: Breast size does not determine cancer risk. But larger breasts can make it more difficult to identify the lump during self-exam or imaging. Hence, regular screening is recommended for everyone regardless of size.

  1. Myth 14: Breast pain is always a sign of breast cancer.

Fact: Most breast pain is not related to cancer. It is caused by hormonal changes, infections, or cysts. However, if you have consistent pain followed by a lump or abnormal discharge, you must get yourself tested.

  1. Myth 15: All breast cancers are the same.

Fact: Breast cancer is not a single condition. It has various stages and types, such as hormone receptor-positive, HER2-positive/negative, and triple-negative breast cancer; each type needs to be treated differently.

  1. Myth 16: Carrying a mobile phone in your bra causes breast cancer.

Fact: There is no scientific research that supports a link between mobile phones and breast cancer. It is still best to keep mobile phones away from your body.

  1. Myth 17: Breast cancer is contagious.

Fact: Breast cancer will not spread from person to person. It is caused by genetic mutations and other biological factors.

  1. Myth 18: If you have a BRCA1 or BRCA2 gene mutation, you will definitely get breast cancer.

Fact: Having a gene mutation certainly increases your risk, but it does not guarantee that you will have cancer. Many people with these mutations never get cancer in their lifetime, especially with regular screening and preventive care.
