20-22. >22. Worldwide, breast cancer is the most common invasive cancer in women. [note 1] Breast cancer comprises 22.9% of invasive cancers in women [2] and 16% of all female cancers. [3] In 2008, breast cancer caused 458,503 deaths worldwide, which is 13.7% of cancer deaths in women and 6.0% of all cancer deaths for men and women together. [2]
Breast cancer awareness is an effort to raise awareness and reduce the stigma of breast cancer through education about screening, symptoms, and treatment. Supporters hope that greater knowledge will lead to earlier detection of breast cancer, which is associated with higher long-term survival rates, and that money raised for breast cancer will ...
Age is the biggest risk factor for breast cancer. The risk of getting breast cancer increases with age. A woman is more than 100 times more likely to develop breast cancer in her 60s than in her 20s. [4] The risk over a woman's lifetime is, according to one 2021 review, approximately "1.5% risk at age 40, 3% at age 50, and more than 4% at age 70."

The American Cancer Society reports 5-year relative survival rates of over 70% for women with stage 0-III breast cancer with a 5-year relative survival rate close to 100% for women with stage 0 or stage I breast cancer. The 5-year relative survival rate drops to 22% for women with stage IV (metastatic) breast cancer. [3]

Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
