Stress, Neighborhood Violence, and Health.

Learn how stress, violence, and health disparities contribute to higher lung cancer and disease risks in Black men. Also see below for helpful resources to take action for your health and get involved with your community.

Black men have higher rates of death for several diseases, including lung cancer.

Being exposed to neighborhood violence may increase your risk of lung cancer and other diseases.

  • The body's response to physical, mental, or emotional pressure (NCI)

  • Weakened immune system

    Heart disease

    High blood pressure

    High blood sugar

    Digestive Issues

    Nerve problems

  • The body’s chemical response to fight infection or heal damaged body parts. Too much unnecessary inflammation can be bad for your body. (NCI)

  • Lung disease

    Heart disease

    Arthritis

    Autoimmune disease

    Ulcers

    Bowel disease

    Nervous disorders

  • Your body getting worse at healing itself

  • Difficulty in fighting off infection

    Contributes to chronic disease

  • Unhealthy behaviors people engage in to ease their pain.

  • Smoking

    Drinking

    Unhealthy diet

    Lack of physical activity

  • The body's response to physical, mental, or emotional pressure (NCI)

  • Wear and tear on the the body due to chronic stress

    Faster biological aging

    Increase risk of disease such as cancer

One way this is possible is through
chronic stress. Our research explored how being exposed to neighborhood violence can increase stress.

Stress can be measured by the stress hormone CORTISOL, which can be detected in your hair. Cortisol is a hormone produced by the adrenal glands that plays a key role in regulating stress, metabolism, and immune response. It helps the body manage how it uses fats, proteins, and carbohydrates, while also influencing blood pressure and sleep cycles. Elevated cortisol levels over time can lead to negative health effects, including weight gain, anxiety, and weakened immunity.

Health disparities can lead to both short and long-term stress. This increase in stress contributes to poor health and lung cancer risk.

This may help explain why Black men have higher rates of lung cancer.
