A disproportionate number of cancers in the United States occur among racial and ethnic minorities. When compared with whites, Hispanics have a higher incidence of cervical cancer, Asians have twice the rate of stomach cancer, and African Americans have a higher incidence of prostate, lung, colon, oral, cervical, and stomach cancer.
Increased access to cancer screening services and earlier detection may improve cancer outcomes among minorities; however, differences in cancer survival and mortality between minorities and whites still exist. "This observation suggests that factors other than the stage at diagnosis contribute to the disparate cancer mortality observed among racial/ethnic minority populations," the authors say.
Past studies have suggested that a person's race or ethnicity influences their access and use of noncancer medical services. To determine the role race and ethnicity plays in the receipt of cancer treatments, Shavers and Brown re-examined published data from 87 studies of cancer treatment and survival, focusing on racial and ethnic variations in the treatment of patients with breast, cervical, colorectal, prostate, or lung cancer.
The authors found consistent racial and ethnic differences in the receipt of primary therapy, conservative therapy, and adjuvant therapy. For instance, white patients often received more aggressive therapy than other racial and ethnic groups for lung, prostate, and colorectal cancers. In contrast, whites received less aggressive therapy-such as
