When it comes to health decisions, especially as we age, it’s easy to rely on our chronological age as the primary guide. However, there’s a growing consensus among medical experts that a more meaningful number should be steering our choices—our life expectancy. This shift in focus could change the way you approach your health and ensure that your decisions align with your long-term well-being.

The Reality of Age-Based Health Decisions

Imagine you’re 76 years old, sitting in your doctor’s office for your annual check-up. The doctor asks whether you plan to continue regular mammograms for breast cancer screening and reminds you that it’s been nearly a decade since your last colonoscopy. At this stage in life, you might wonder if these screenings are still necessary.

According to the latest draft guidelines from the U.S. Preventive Services Task Force (USPSTF), the benefits of certain screenings, like mammograms for women over 75, are increasingly uncertain. Similarly, for colorectal cancer screening, the task force assigns a C grade for those aged 76 to 85, indicating that the net benefit is likely small. They recommend that such screenings be offered selectively, depending on the individual’s circumstances.

This approach isn’t just limited to cancer screenings. Organizations like the American College of Physicians and the American Cancer Society are incorporating life expectancy into their screening guidelines, recognizing that age alone isn’t always the best predictor of who will benefit from certain medical interventions. So, how can you find out what your life expectancy might be?

How to Estimate Your Life Expectancy

Understanding your life expectancy can provide a more personalized basis for making health decisions. Thankfully, there are several apps and online tools available that can help you with this. These tools consider your overall health, lifestyle, and other factors to provide a more accurate picture than age alone.

1.     ePrognosis

ePrognosis is one of the most comprehensive tools for estimating life expectancy in older adults. Developed by geriatricians and researchers in 2011, this tool includes over two dozen validated geriatric scales that estimate mortality and disability. While initially designed for healthcare professionals, it is also accessible to consumers who want to make informed decisions about their health. ePrognosis incorporates detailed information about your health history and current functional abilities. It even features a “time to benefit” tool, which helps you understand which screenings and interventions are likely to be beneficial based on your life expectancy.

2.     American College of Cardiology Risk Estimator

Cardiovascular health is a significant concern as we age, and the American College of Cardiology’s ASCVD Risk Estimator can help you assess your risk for heart disease and stroke. This tool calculates your 10-year risk of atherosclerotic cardiovascular disease based on factors such as age, cholesterol levels, blood pressure, smoking status, and diabetes. By understanding your risk, you can work with your healthcare provider to decide on preventive measures that align with your life expectancy.

3.     National Cancer Institute Breast Cancer Risk Assessment Tool

For women concerned about breast cancer, the National Cancer Institute offers a Breast Cancer Risk Assessment Tool. This calculator estimates your risk of developing breast cancer in the next five years and over your lifetime, based on personal and family medical history. This information can help you and your doctor decide whether to continue with regular mammograms or other preventive measures.

4.     Memorial Sloan Kettering Cancer Center Lung Cancer Screening Tool

If you’re at risk for lung cancer, the Memorial Sloan Kettering Cancer Center provides a Lung Cancer Screening Decision Tool. This tool assesses your risk based on smoking history, age, and other factors, helping you determine whether lung cancer screening is a wise choice for you. Given the varying risks and benefits of screening in older adults, this personalized approach can be crucial in making informed decisions.

Why Life Expectancy Should Guide Your Health Choices

These tools offer a more nuanced approach to healthcare by focusing on life expectancy rather than age alone. As we grow older, our health decisions should be based on the likelihood that a particular screening or treatment will benefit us in the years we have ahead. By understanding your life expectancy, you can make decisions that enhance your quality of life and avoid unnecessary procedures that may not offer significant benefits.

The concept of using life expectancy as a guide is gaining traction in the medical community. A New York Times article recently highlighted how life expectancy increasingly figures into calculations about whether screenings and treatments are appropriate for older adults. The article discusses how health institutions are adapting to this shift, offering calculators and tools to help both doctors and patients make more informed choices.

What’s Your Take?
