A new study has found that nearly 2.3 million women have had breast cancer in the United States in the past 15 years.
The study, conducted by the Centers for Disease Control and Prevention and the American Cancer Society, used data from the National Health Interview Survey, an ongoing survey of more than 2.2 million Americans.
The number of new breast cancer cases in the US rose by 5% over the past 10 years.
That’s a huge increase over previous estimates.
The researchers used the survey data to estimate the number of women who had had a diagnosis of breast cancer.
In the last 15 years, the number rose by 8% and the number with metastatic disease was almost doubling.

The majority of women (76%) had a breast cancer diagnosis during the last five years, and nearly half (47%) of women diagnosed during the same time period had metastatic breast cancer, according to the study.
The new data showed that in the last decade, the most common diagnosis of invasive breast cancer was hysterectomy, followed by non-Hodgkin lymphoma and malignancies.
The highest number of cases of non-malignancies was among black women.
“Breast cancer is one of the most underreported cancers in the country, yet our current numbers of breast cancers are well above the average,” said Dr. Nancy F. Kranz, a professor of pediatrics at the University of Pennsylvania.
The researchers found that the incidence of nonviable breast cancer increased by 2% per year over the last 10 years, from about 11,000 cases per year in the 1990s to nearly 18,000 in 2015.
According to the CDC, more than 8.6 million women in America will have a breast biopsy in their lifetime.
The numbers of new cancer diagnoses are up in the U.S. in recent years.
In 2015, the U,S.
saw nearly 13,000 new breast cancers, up from 5,600 in 2013.
There were 1,542,000 women diagnosed with a malignance in the 10-year period studied.
About 1 in 20 women will develop a malignant breast cancer during that time.
