Indicator Profile of Incidence of Breast Cancer in Females

Why Is This Important?

In New Jersey, over 6,800 women were diagnosed with breast cancer in 2009. Breast cancer is the most common cancer among women in the United States, other than skin cancer. It is the second leading cause of cancer death in American women, after lung cancer.

There are a variety of risk factors for breast cancer. Women have a breast cancer rate about 100 times higher then men; and the risk of getting breast cancer increases with age. Around 5 to 10% of breast cancers are thought to be linked to inherited mutations in certain genes. Women with a family history of breast cancer, as well as a personal prior history of breast cancer, are more likely to get breast cancer. White women appear to have higher risk of breast cancer than African-American women, while Asian, Hispanic and American Indian women have lower risks of getting breast cancer. Other factors that increase a woman's risk of breast cancer include: having dense breast tissue; starting menstrual periods before age 12 or going through menopause after age 55; radiation to the chest area; not having children or having a first child after age 30; recent use of birth control pills; usage of some types of postmenopausal hormones; not breast feeding; consuming 2 or more alcoholic drinks per day versus not drinking alcohol; being obese or overweight; and getting little physical exercise.

Data Notes

Incidence rates (cases per 100,000 population per year) are age-adjusted to the 2000 US standard population (19 age groups: <1, 1-4, 5-9, ... , 80-84, 85+). Rates are for invasive cancer only (except for bladder cancer which is invasive and in situ) or unless otherwise specified. Data retrieved April 18, 2012 from New Jersey Department of Health, New Jersey State Cancer Registry, web site http://www.cancer-rates.info/nj/. Data for 2008 and 2009 are considered preliminary due to possible reporting delays.
