Who Is At Risk For Breast Cancer
Risk factor is anything that affects your chances of getting diseases such as cancer. Different cancers have different risk factors. For example, Smoking is a risk factor for lung cancer, larynx (voice box), kidney, bladder, mouth, and other organs, exposing skin to strong sunlight is a risk factor for skin cancer
Most women who have one or more risk factors for breast cancer, while many women with breast cancer have no obvious risk factors. Even when a woman with risk factors for developing breast cancer, it is difficult to know exactly how many factors contribute to cancer.
Several factors, such as a person's age or race, cannot be changed. Others associated with cancer-causing factors in the environment as well as personal behaviors, like smoking, drinking diet, and some other factors, and your risk for breast cancer can change over time, due to factors such as aging or lifestyle.
Risk factors you cannot change
Gender
Women have more breast cells than men, the main reason they develop more breast cancer, because their breast cells are constantly exposed to growth-promoting effects of female hormones estrogen and progesterone
Aging
Your risk of developing breast cancer increases as you get older. Women under age 45 have a small risk of breast cancer, than women over age 55
Genetic risk factors
about 5% to 10% of breast cancer cases are considered hereditary, so it directly from the defective gene (called mutations) inherited from the parents. BRCA1 and BRCA2: The most common causes of hereditary breast cancers are inherited mutations in BRCA1 and BRCA2 genes. In normal cells, these genes help prevent cancer by making proteins that help maintain the cells grow abnormally.
If you have inherited a mutated copy of either gene from a parent, you have an 80% risk of developing breast cancer during your lifetime. This cancer tends to occur in younger women and more often affects both breasts than cancer in women who are not born with one mutated gene.
