  • FAMILY HISTORY OF BREAST CANCER: The chances to have breast cancer increases to two folds if a person having first degree relative (mother, sister, daughter) breast cancer & the chances to get this problem increased to five folds if the person having two first degree relatives.
  • FEMALE GENDER: 99% of the breast cancer cases occur in females as compared to males.
2). HORMONAL FACTORS: These are the factors that are directly related to the level of hormones in the body. These are as follows:
  • MENSTRUATION: The women who are having their menarche (starting of menstruation) at earlier age that is before 12 years if age & late menopause (cessation of menstrual cycle) that is after 55years of age are at a greater risk of developing breast cancer.

  • HORMONAL THERAPY: The women using oral contraceptives continuously from last 10 years & use of hormonal therapy after menopause are at a risk to develop breast cancer.
3). ENVIRONMENTAL FACTORS: These are the factors that present in the environment:
  • EXPOSURE TO IONIZING RADIATION: The risk is more if a girl exposed to ionizing radiation during adolescent period because at this time the breast tissues are still developing and have a greater chances of mutations.
4). PERSONAL FACTORS: These factors are related to a person’s own life-style. These are as follows:
