Epidemiological features of breast cancer: a retrospective study; Part III: the odd risk of some hormonal aspects

ABSTRACT

The index sample was female patients attending Alexandria University Main Hospital at the Surgical and radiotherapy departments as well as the Medical Research Institute during the year 1982-1983 [n=174]. The control group included 171 patients from the same Hospital thoroughly examined to exclude the presence of breast lump. The aim of this study is to find out the extent of risk from cancer breast as regards regularity of menstruation, artificial menopause, use of contraceptive pills and exposure to hormonal treatment. The study revealed that breast cancer risk was significantly higher among pill users as well as those receiving hormonal treatment for whatever reason [excluding the present condition]. Artificial menopause seemed to have a protective value
