Family History: When You Should Start Imaging Screenings Early

Standard screening guidelines are written for people with average risk. But if cancer, heart disease, or osteoporosis runs in your family, you may not be average risk — and waiting until the standard age to start screening could mean missing early warning signs.

Why Family History Changes the Rules

Your genes play a significant role in your health. According to the Centers for Disease Control and Prevention, people with a close relative (parent, sibling, or child) who had certain diseases are at higher risk themselves. This is especially true for breast cancer, colon cancer, heart disease, osteoporosis, and lung cancer.

When your family history puts you at elevated risk, medical organizations recommend starting screenings earlier and sometimes more frequently than the general population.

Breast Cancer and Family History

The American Cancer Society recommends that women at high risk for breast cancer begin screening with both a mammogram and a breast MRI at age 30 — a full decade earlier than standard guidelines.

You may be considered high risk if:

• A first-degree relative (mother, sister, daughter) had breast cancer
• You carry a BRCA1 or BRCA2 gene mutation
• You received radiation therapy to the chest between ages 10 and 30
• You have a lifetime risk of 20 percent or more based on risk assessment models

At AMI, our 3D mammography uses Hologic tomosynthesis technology, which is especially effective for high-risk women because it can detect cancers hidden within dense breast tissue.

Heart Disease and Family History

Heart disease is the leading cause of death in the United States, and it has a strong genetic component. The American Heart Association states that having a father or brother who had heart disease before age 55, or a mother or sister before age 65, significantly increases your risk.

If heart disease runs in your family, talk to your doctor about:

• Cardiac calcium scoring — A quick CT scan that measures plaque in your coronary arteries
• Echocardiogram — An ultrasound of the heart to check heart function and valve health
• Carotid ultrasound — To check for plaque in the arteries supplying blood to the brain

These tests can be done years before the standard recommended age if your family history warrants it.

Osteoporosis and Family History

If your mother or father had a hip fracture or was diagnosed with osteoporosis, your risk of developing the disease is significantly higher. The National Osteoporosis Foundation notes that family history is one of the most important risk factors for low bone density.

A DEXA scan can detect bone loss years before a fracture occurs. While standard guidelines recommend DEXA screening for women at age 65 and men at age 70, your doctor may recommend earlier testing if you have a family history of osteoporosis, are underweight or have a small frame, take long-term corticosteroids, or had early menopause.

How to Share Your Family History With Your Doctor

Many people do not know their complete family medical history. Before your next checkup, try to gather information about first-degree relatives (parents, siblings, and children), what diseases they had and at what age they were diagnosed, and whether anyone died from cancer, heart disease, or stroke at a young age.

Even incomplete information is helpful. Your doctor can use what you know to determine whether you need earlier or more frequent screening.

Do Not Wait for Symptoms

The whole point of screening is to catch disease before symptoms appear. If you have a strong family history, the standard timeline may not protect you. Talk to your doctor, understand your risk, and get the imaging you need.
