I've been with my girlfriend for three years. Yesterday, I took her to have a regular physical examination. I found that she seems to have a breast disease. I especially hope that she can be cured soon. Now I'm going to learn why girls get breast cancer.

Why do girls get breast cancer

First: Although there are cases of men suffering from breast cancer, the number of men receiving breast cancer in the United States is less than 1% of the 180 000 breast cancer patients each year. Breast cancer is the number one killer of women after skin cancer. The national cancer prevention research center points out that the average American woman's chance of developing breast cancer at the age of 40 is 1 / 217. At the age of 45, the chance of developing breast cancer increases to 1 / 93. But if a woman lives to 85, her chance of developing breast cancer is as high as 1 / 8.

Second: menstrual cycle factors - 12 years old before menstruation, or 55 years old after complete menopause. Family history factor - the mother, aunt, sister, cousin or daughter of the family had breast cancer. Taking contraceptives - the risk of breast cancer is slightly higher if you are currently using contraceptives or have used them in the past 10 years. Children - those who have not given birth or are pregnant after the age of 30.

Third: drinking more than two glasses of alcohol a day. Overweight - especially after menopause, people who eat a high calorie diet. Chest radiation therapy - a person who has received chest radiation therapy in childhood or adolescence. Gene mutation - breast cancer genetic predisposing gene BRCA1 (located on human chromosome 17) or BRCA2 (located on human chromosome 13).
