The endometrium is a layer of cells covering the inside of the uterus. At the beginning of each menstrual cycle, it thickens to possibly host an embryo in the timing of nidation, organic process whereby a fertilized egg becomes implanted in the lining of the uterus. If at the end of the menstrual cycle, no embryo has implanted, much of the uterine lining peels off, thus constituting the menstrual period .
Unfortunately, sometimes those cells are not released from the body during the menstrual period, and pathogenically accumulate in the uterine. Even in women who stop having their menstrual cycle (menopausal women), cells lining the inside of the uterus should naturally die to be periodically replaced by new healthy cells. Unfortunately, in some women, those cells continue to live and multiply without control. This uncontrolled cellular alteration causes formation of a malignancy or cancerous growth in the uterine. Although the cause of endometrial cancer is not well known, scientists believe many factors can contribute to the genesis of the disease: environment, chemicals, physical aggression and certain viruses.
Estrogen levels play can also play a major role in the development of endometrial cancer. Although several factors may influence the increased of your estrogen levels, obesity and menopause are the two major causative factors. There is no relationship between endometrial cancer and STDs, in contrast to cervical cancer. The cancer can occur in women who have never had sexual intercourse or HPV infection. Endometrial cancer is more common among women who had few or no children, and women who started menstruating at an early age.
