Women With Fewer Periods Have Low Risk Of Gynecological Cancer

The fewer periods a woman has the better, he says, reported ABC science online.

'In our society women have many more periods than in primitive societies and each menstrual cycle leads to big swings in the ovarian hormones estrogen and progesterone.'

According to Fraser, this over stimulates the reproductive organs and the breasts.

'The uterus, lining of the uterus and breasts were not designed to cope with this and it causes some cells to grow and regress each month, which means a greater chance of error in the proliferation process of abnormal cells,' he says.

In our society, girls menstruate earlier and women have more periods before giving birth.

Women from traditional societies however breastfeed for extended times, often conceive soon after their menses return, average five to six pregnancies and have an earlier menopause - all factors that reduce the number of periods they have in a lifetime.
