About Breast Cancer

Breast cancer is the most frequently diagnosed cancer in women. It is the second-leading cause of cancer death in women after lung cancer, and since 1990 is increasing predominantly in women 50 and over. It is the first cause of cancer mortality in women of 40 to 59 years old. According to the American Cancer Society, an estimated 200,000 women are diagnosed with breast cancer and approximately 40,000 women die of the disease in the United States every year. A woman is diagnosed with breast cancer in the United States every three minutes. The risk of a woman developing breast cancer during her lifetime is approximately 13 percent (about one in seven of all women in the United States). In the European Union, more than 191,000 new cases are diagnosed each year and more than 60,000 women will die. Of women with breast cancer, 20 to 25% of these women will have HER2 positive breast cancers. With earlier screening and diagnosis, early management of patients may offer better chances of survival.
