Is Breast Cancer Hereditary?

Breast cancer risk can be inherited from either parent. It’s a misconception that the risk only comes from the mother. Both BRCA1 and BRCA2 mutations, for example, can be passed down by your mom or dad.

Beyond BRCA1 and BRCA2, other genes like TP53, PALB2, ATM, and CHEK2 can also increase the risk of breast cancer. While these mutations are less common, they also disrupt DNA repair and tumor suppression.

Having a first-degree relative (such as a mother, sister, or daughter) with breast cancer increases your risk. If multiple close relatives have had breast or ovarian cancer, especially at a young age, your genetic risk may be even higher.

If you’re worried about genetic risk, here are some signs to look out for:

• • Multiple family members on the same side of the family (mother’s or father’s) with breast or ovarian cancer.
  • Diagnosis of breast cancer before age 50 in a family member.
  • Triple-negative breast cancer (a type of breast cancer) in your family.
  • Male breast cancer in a relative.

You might consider genetic testing if these factors apply to you. Genetic testing involves analyzing your DNA for mutations like BRCA1 or BRCA2. This is done with a sample of your blood or saliva.

No. If you have a genetic mutation, your risk may be higher, but it’s not a certainty. It’s important to understand the difference between risk and certainty.

Lifestyle factors like maintaining a healthy diet, exercising, and avoiding smoking can significantly influence your overall cancer risk, even if you have a genetic mutation. 

Only precaution you have to take is get your frequent and regular screening tests like mammo-sonography and abdomen sonography. 

So that if this cancer affects you, you should be able to detect it early. Most cases of breast cancer are not hereditary, meaning they are linked to lifestyle or environmental factors.

While you can’t eliminate all risks, there are many ways to manage hereditary breast cancer risk, including:

1. Surveillance and Early Detection

• • Regular screenings like mammograms or MRI scans can catch cancer early when it’s most treatable.
  • Some people at high risk may start screenings earlier than the general population.

2. Healthier Lifestyle Choices

• • Exercise regularly and maintain a healthy weight.
  • Limit alcohol intake and avoid smoking. Research shows that these lifestyle changes reduce overall cancer risks.

3. Medical Prevention Options

• • Medications like tamoxifen or raloxifene (chemoprevention) can lower the risk of developing breast cancer, especially in high-risk women.
  • Preventive surgeries (like double mastectomy or oophorectomy) may also be an option for people with BRCA mutations. These surgeries reduce the risk of developing breast or ovarian cancer by removing tissues most likely to grow cancer cells.

Talk to your doctor or genetic counsellor at KCC Hospital to weigh the pros and cons of each option based on your specific concerns.

Yes, men can inherit genetic mutations like BRCA1 or BRCA2, putting them at higher risk of breast cancer (and other cancers like prostate cancer).

Though male breast cancer is rare, men with a family history need to be aware of symptoms, such as a lump in the chest area, swelling, or discharge.

If you’re a man with a BRCA mutation, your doctor may recommend increased surveillance or genetic counseling for guidance.

It’s not just about genetics. Other risk factors include:

• • Age: Most cases occur in women over 50.
  • Hormone levels: Prolonged use of hormone replacement therapy or early menstruation (before age 12) can increase risk.
  • Lifestyle factors: Obesity, lack of exercise, and alcohol intake can raise your risk.

Genes often interact with these lifestyle factors, so making healthy choices is always a smart move.

Let’s set the record straight on some common myths:

🚫Myth: If no one in my family has breast cancer, I won’t get it.
✅ Truth: Most cases of breast cancer are not hereditary. You could still develop breast cancer due to other factors.

🚫Myth: Men cannot inherit breast cancer genes.
✅ Truth: Men with BRCA mutations are at higher risk for breast cancer and other cancers.

🚫Myth: A positive genetic test means I will get cancer.
✅ Truth: A positive test means your risk is higher, but it does not guarantee you will develop cancer.

You should consider seeing a doctor or genetic counselor if:

• • Several close relatives have had breast or ovarian cancer.
  • There are cases of breast cancer diagnosed before age 50 in your family.
  • You have tested positive for BRCA1, BRCA2, or another mutation.

During a genetic counseling session, you’ll review your family history, discuss testing options, and understand what test results mean for you and your loved ones.

If you’re concerned about your family history or risk factors, don’t wait. Schedule an appointment with a doctor or genetic counsellor to gain clarity and take control of your health. Early awareness and proactive measures could make all the difference.

The role of genetics in breast cancer is important, but it’s just one piece of the puzzle. Knowing your family history, considering genetic testing, and making healthy lifestyle choices are all steps you can take to manage your risk.

If you’re concerned about hereditary breast cancer, don’t wait. Talk to your doctor or genetic counselor today to explore your options and create a plan tailored to your needs. Early action can make a big difference!
