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 ...
One of their recent publications was a 2019 meta-analysis of menopausal hormone therapy and breast cancer risk based on type and timing of therapy. [1] In 2012, the group concluded in a meta-analysis of 117 studies that the incidence of breast cancer was increased by each year younger at menarche and each year older at menopause. [4]
Breast cancer incidence by age in women (UK) 2006-08 [21] Breast cancer is the most common cancer in the UK (around 56,000 women and 375 men are diagnosed with the disease every year).

For example, the incidence of breast cancer in a woman in the United Kingdom at age 55 to 59 is estimated at 280 cases per 100.000 per year, [6] and the risk factor of having been exposed to high-dose ionizing radiation to the chest (for example, as treatments for other cancers) confers a relative risk of breast cancer between 2.1 and 4.0, [7 ...
With his work focused on breast cancer research, Clarke studies how hormones (endogenous and exogenous) and related factors affect breast cancer. He has authored over 360 publications, [3] [4] and he has 5 patents awarded. His research primarily focuses on understanding the endocrine responsiveness of breast cells and the likelihood that breast ...
She has studied how air pollution, [10] [11] persistent organic pollutants and second hand smoke can impact human health, and how risk is distributed across America. [12] [13] Laden has studied the environmental risk factors of various cancers, including breast cancer, lung cancer and non-Hodgkin's lymphoma. [14]
Triple-negative breast cancer comprises 15–20% of all breast cancer cases [3] and affects more young women or women with a mutation in the BRCA1 gene than other breast cancers. [4] Triple-negative breast cancers comprise a very heterogeneous group of cancers. TNBC is the most challenging breast cancer type to treat. [5]
