Factors That Contribute to Health Disparities in Cancer

Socioeconomic Status

(Education, income, and employment)
Research shows a link between poverty and low educational achievement and increased cancer deaths among minority populations.¹

Access to and Use of Health Care Services

(Cancer screening tests)
Research shows inequalities in the use of preventive and primary care services. Also, minorities are more likely to be uninsured or underinsured.¹

Behaviors

(Physical activity, diet, and tobacco use)
Physical inactivity and unhealthy eating contribute to several chronic diseases, including some cancers.² Tobacco use is a well-established risk factor for lung and other cancers.³ The prevalence of cigarette smoking is higher among some racial and ethnic minorities than whites.⁴

Social Environment

(Educational and economic opportunities, racial or ethnic discrimination, and neighborhood and work conditions)¹
Some communities lack the basic resources that everyone needs for a healthy life. These include healthy food, safe housing, living-wage jobs, decent schools, supportive social networks, and access to health care. Social environments lacking basic resources present the highest public health risk for serious illness and premature death.

Exposure to Carcinogens

(Substances that are known or appear likely to cause cancer)⁵
A person's physical environment, workplace, socioeconomic status, and other factors can affect his or her chances of being exposed to cancer-causing substances.

Treatment

Because minorities often do not receive timely treatment, or are treated at a later stage of cancer,⁶ their survival rates are lower than those of whites.⁷
