Ovarian Cancer Risks Cut in Half With a New Birth Control Pill: Study

Previous research had shown that the older products, containing higher levels of oestrogen and older progestogens, were tied to reduced ovarian cancer risk.

New types of combined birth control pills — containing both lower doses of oestrogens and newer progestogens — may reduce the risk of ovarian cancer among young women, says a study.

The study, published in the journal The BMJ, showed that this positive effect strengthened with longer periods of use and persisted for several years after stopping.

“The reduced risk seems to persist after stopping use, although the duration of benefit is uncertain,” the study said.

At least 100 million women worldwide use hormonal contraception every day.

For the study, the researchers from University of Aberdeen in Scotland and the University of Copenhagen in Denmark analysed data for nearly 1.9 million Danish women aged 15-49 years between 1995 and 2014.

Women were categorised as never users (no record of being dispensed hormonal contraception), current or recent users (up to one year after stopping use), or former users (more than one year after stopping use) of different hormonal contraceptives.

Most (86 per cent) of the hormonal contraceptive use related to combined oral products.

The researchers found that the number of cases of ovarian cancer were highest in women who had never used hormonal contraception (7.5 per 100,000 person years), whereas among women who had ever used hormonal contraception, the number of cases of ovarian cancer were 3.2 per 100,000 person years.

The reduced risk for combined products was seen with nearly all types of ovarian cancer, and there was little evidence of important differences between products containing different types of progestogens.

“Based on our results, contemporary combined hormonal contraceptives are still associated with a reduced risk of ovarian cancer in women of reproductive age, with patterns similar to those seen with older combined oral products,” the study authors said.

But it was not known whether the newer contraceptives carried the same benefit. (IANS)

Light Physical Activity May Lower CVD Risk in Women: Study

While strolling or running are beneficial for heart health, light physical activity, such as gardening and folding clothes, may also lower the risk of cardiovascular diseases (CVD) in older women, say researchers.

The study showed that such activities might be enough to significantly reduce stroke or heart failure by up to 22 per cent and the risk of heart attack or coronary death by as much as 42 per cent.

The association was strong across all racial and ethnic groups, noted the study published in the journal JAMA Network Open.

“The higher the amount of activity, the lower the risk,” said co-author Andrea LaCroix, Researcher at the University of California, San Diego.

“And the risk reduction showed regardless of the women’s overall health status, functional ability or even age. In other words, the association with light physical activity was apparent regardless of these other factors,” LaCroix added.

For the study, researchers studied nearly 6,000 women aged 63 to 97. They were made to wear a device which measured their movement 24 hours a day for seven consecutive days. The device was also calibrated by age to distinguish between light, and moderate-to-vigorous physical activity.

“This study suggests that for older women, any and all movement counts towards better cardiovascular health,” said David Goff, Director at National Heart, Lung, and Blood Institute (NHLBI) in the US. (IANS)
