Age is a significant risk factor for prostate cancer, the most common cancer among men. As men grow older, various physiological changes occur that can increase the risk of developing prostate cancer. This page explores these age-related changes and their implications for prostate health.

Age-Related Physiological Changes

  1. Hormonal Imbalance: With age, men experience a natural decline in testosterone levels, which average around 630 ng/dL in younger adults (20-40 years) but decrease significantly after the age of 50. Concurrently, the enzyme aromatase converts a portion of this diminishing testosterone into estradiol, a form of estrogen. This hormonal shift, characterized by lower testosterone and higher estradiol levels, is a crucial factor in prostate health and cancer risk.
  2. Prostate Size Increase: As men age, changes in prostate size are common. In young adults, a healthy prostate is about the size of a walnut, typically measuring 13-15 cm³. However, an increase in prostate size is a common age-related change. If you find yourself making regular nighttime trips to the bathroom, it’s a sign that your prostate has grown significantly. Usually, it may reach 30-40 cm³, sometimes exceeding 100 cm³. This enlargement, known as benign prostatic hyperplasia (BPH), is not prostate cancer, but it is an indicator of changes occurring in the prostate due to aging.
  3. Environmental Factors: Older men have a higher cumulative exposure to harmful chemicals and heavy metals, which can contribute to cellular damage and increase cancer risk.
  4. Stress and Aging: Aging is also associated with increased stress levels, which can affect hormonal balance and overall health, potentially influencing cancer risk.

Lifestyle Choices for Mitigating Risk

Making informed lifestyle choices is crucial in reducing the impact of these age-related changes. This includes:

  • Diet and Nutrition: A balanced diet rich in fruits, vegetables, whole grains and low in red and processed meats can support prostate health.
  • Regular Exercise: Physical activity helps maintain hormonal balance and overall health.
  • Stress Management: Techniques such as meditation, yoga, or even regular leisure activities can help manage stress levels.
  • Reducing Exposure to Toxins: Minimizing exposure to harmful chemicals and heavy metals, whether in the workplace or through lifestyle choices, can reduce cancer risk.


Understanding the role of age in prostate health is vital for early detection and prevention strategies. Regular health check-ups, including prostate screenings, are essential as men age. By being aware of these age-related changes and making proactive lifestyle choices, men can significantly impact their prostate health and reduce the risk of prostate cancer.
