Younger women generally do not consider themselves to be at risk for breast cancer. Only 5 percent of all breast cancer cases occur in women under 40 years old. However, breast cancer can strike at any age, and all women should be aware of their personal risk factors for breast cancer.

There are several factors that put a woman at high risk for developing breast cancer, including:

• A personal history of breast cancer or non-cancerous breast disease.
• A family history of breast cancer, particularly in a mother, daughter or sister.
• History of radiation therapy Evidence of a specific genetic defect (BRCA1/BRCA2 mutation). Women who carry defects on either of these genes are at greater risk for developing breast cancer.
• A Gail Index score of at least 1.7% (The Gail Index uses risk factors such as age, family history of breast cancer, age of first menstrual period and first pregnancy, and number of breast biopsies to calculate a woman’s risk of developing breast cancer within the next five years.)
• An extended use of oral contraceptives (the Pill) later in life is also sometimes considered a factor for developing breast cancer. However, this is still subject to much debate in the medical community.

While breast cancer may not be prevented, early detection and prompt treatment can significantly improve a woman’s chances of surviving breast cancer. More than 90% of women whose breast cancer is found in an early stage will survive.

When women learn at a young age about the risks and benefits of detecting breast cancer early, they are more likely to following the recommendations regarding clinical exams and mammograms . Young women also need to understand their risk factors and be able to discuss breast health with their health care providers.
