7 Common Misconceptions About Breast Cancer

1 in 8 women will develop breast cancer. Early detection through self-examinations, screening, and BRCA gene testing can improve outcomes, even be curative. Maintaining a healthy weight, regular exercise, and limiting alcohol intake can help lower the risk.

Mammograms are an effective tool for detecting early-stage breast cancer. Most guidelines recommend starting at age 40, but screening can begin earlier for individuals with higher risk. Here are 7 common misconceptions about breast cancer and what the evidence actually shows.

Misconception 1:

Most people who get breast cancer have a family history.

Fact:
Around 80–90% of breast cancer patients do not have a family history. Only 5–10% are linked to inherited gene mutations like BRCA1 or BRCA2. The main risk factors are being female and increasing age. Routine screening is important for all women, especially after age 40.

Misconception 2:

Screening guidelines are the same for everyone.

Fact:
People with a family history of breast cancer may need to start screening earlier. If your mother or sister was diagnosed at age 45, you should start screening at age 35. Those with a BRCA mutation may start as early as age 25, sometimes with both mammogram and MRI.

Misconception 3:

Only women get breast cancer.

Fact:
Men can also get breast cancer, although it's rare. Men with BRCA1 have a 1–2% lifetime risk, while men with BRCA2 have a 7–10% risk — similar to women. Men with family history or gene mutations should also discuss screening with a doctor.

Misconception 4:

Eating sugar increases the risk of breast cancer.

Fact:
There's no solid evidence linking sugar intake directly to breast cancer. However, maintaining a balanced diet is important, especially for those with diabetes or obesity, as these conditions may increase cancer risk.

Misconception 5:

A few alcoholic drinks per week are safe.

Fact:
There is no confirmed "safe" amount of alcohol when it comes to cancer risk. Even low levels of alcohol can increase the risk of several cancers, including breast cancer. Reducing alcohol intake is advised.

Misconception 6:

If you tested negative for BRCA 10 years ago, there's no need to test again.

Fact:
Genetic testing has advanced. Earlier tests may not have included other cancer-related genes such as PALB2, CHEK2, or ATM. If your test was done before 2013, talk to your doctor about retesting with an updated gene panel.

Misconception 7:

Only certain ethnic groups need BRCA testing.

Fact:
BRCA mutations are found across all ethnicities. While some groups have higher rates, no group is risk-free. Testing should be considered based on personal or family cancer history, not just ethnicity.

When Should You Be Screened?

• Women age 40 and above

• Anyone with a family history of breast, ovarian, or prostate cancer

• Those with known genetic mutations or past genetic testing before 2013

Screening recommendations may vary depending on your personal risk. Consult your doctor to create a screening plan that fits your health profile.

Summary

Many people still believe outdated or inaccurate information about breast cancer. Understanding your personal risk and following proper screening guidelines can make a significant difference. If you're unsure when or how to start, speak with your healthcare provider.
