Breast Cancer Statistics for 2002

Expected Number of New Cases of Breast Cancer

In 2002 it is anticipated that 203,500 women and 1,500 men will develop invasive breast cancer. New cases of in situ breast cancers will account for an additional 64,500 cases this year. The majority of these will be ductal carcinomas in situ. The most common cancers diagnosed in women are breast, lung and colorectal. Overall, breast cancer will account for 31 percent of all cancers diagnosed in women this year.

The differences between racial and ethnic groups can best be illustrated by comparing the incidence of breast cancer cases per 100,00 female population.

 Caucasion 115.5
African American 101.5
Asian/Pacific Islander 78.1
Hispanic/Latina 68.5
Native American 50.5

Expected Number of Breast Cancer Deaths

The estimated number of breast cancer deaqths in 2002 is 39,600 for women and 400 for men. Breast cancer is the leading cause of cancer deaths in women ages 20-39 and 40-59 while breast cancer is surpassed by lung cancer as the leading cause of cancer death for women 60 years and older. j The annual mortality rates per 100,000 female population by racial and ethnic group are as follows:

 Caucasion 24.3
African American 31.0
Asian/Pacific Islander 11.0
Hispanic/Latina 14.8
Native American 12.4

The death rate from breast cancer decreased by 1.6 percent a year from 1989 to 1996 and by 3.4 percent since then. The largest decreases have been observed in younger women, both caucasion and African American. The decline in the mortality rate is attributed to both early detection and improved treatment.

Five Year Survival Rates

For breast cancer that is localized to the breast, the five-year relative survival rate is 96 percent. When breast cancer has spread regionally, i.e., the underarm lymph nodes, the five-year relative survival rate is 78; percent. Women who are diagnosed wiwth distant metastasis (i.e. bone, liver, lungs) have a 21 percent five-year relative survival rate.
