A New Breast Cancer Risk
This is the first study analyzing breast density changes, over time, in an individual breast (rather than averaging the two breasts). While breast density typically declines with age, a slower rate of decline in one breast (than the other) often precedes a cancer diagnosis in that breast.... Read More
Breast Cancer and Genes
Not all who have a BRCA mutation will develop cancer, but having such a gene mutation increases the cancer risk. For example, about 50 percent of women with a BRCA1 or BRCA2 mutation will be diagnosed with breast cancer by age 70, compared with seven out of 100 in the general USA population.... Read More
Drop Your Breast Cancer Risk
Higher physical activity levels appeared to lower breast cancer risk by nearly one-quarter (a drop of 22 percent in relative risk). This risk reduction appeared similar in pre-and postmenopausal women and for high- versus light-intensity movement.... Read More

Less than five percent of women diagnosed with breast cancer in the USA are younger than 40. About half of women with breast cancer will be diagnosed after age 60. While the incidence of breast cancers driven by estrogen increases with age, the incidence of estrogen receptor-negative breast cancer increases until age 50, then levels off.... Read More
