Although breast cancer rates have been decreasing since the early 2000s, it's still the most common type of cancer in women, aside from some kinds of skin cancer, ccording to the Centers for Disease Control and Prevention. It is also the most common cause of death from cancer among Hispanic women and the second most common cause of death from cancer among white, black and Asian/Pacific Islander women.
Using the most recent data (2014) from the National Cancer Institute, the following is a look at breast cancer incidence rates across the United States. Incidence rates reflect the average number of new cases per 100,000 people from 2000-2014, age-adjusted to population. Age-adjusting the numbers allows for rate comparisons between states with different age demographics.
The average woman born in the United States has a 12.4 percent chance of developing breast cancer in her lifetime, according to the National Cancer Institute. Increased alcohol consumption, never giving birth or giving birth for the first time after age 30, or being physically inactive throughout life, along with several other factors, may increase a woman's risk of breast cancer.
These risks, as well as environmental factors such as industrial chemicals and certain pesticides, affect someone's chances of developing cancer, which may explain some of the differences in cancer rates between states.
Here's a look at states ranked from the lowest to highest breast cancer incidence rates.
Note: Nevada was excluded due to insufficient data, and Washington D.C. and Puerto Rico were included.
