A research report suggests that women who use intrauterine devices (IUDs) as birth control may be less likely to develop ovarian cancer
Scientists analyzed evidence from 11 previous studies which tracked details at individual levels for several hundred thousand people on IUD and ovarian cancer diagnosis. In fact, the incidence of ovarian cancer in people using IUDs has been 32% smaller than in other groups.
Dr. Saketh Guntupalli, a senior study author and head of gynecologic oncology at the University of Colorado School of Medicine, Aurora, said that: “We have learned in numerous smaller trials that IUDs may decrease risk for the development of ovarian cancer.
“A total of thousand patients were examined in the current study, making it the largest of its kind,” Guntupalli said by email.
IUDs are quarter-sized T-shaped tubes implanted into the cervix to prevent pregnancies. Devices can be used for years; by preventing semen from entering the egg they prevent conception. Many IUDs produce low hormone concentrations that make it harder for sperm to penetrate the egg by thickering the mucus of the cervix.
While the study does not decide if or how IUDs could aid cancer prevention explicitly, the Guntupalli claimed that two hypotheses are possible.
Oestrogen development which allows the tumors to develop is inhibited by hormonal IUD. Therefore, the involvement of an alien body in the vagina can cause a low level of inflammatory response which tends to mobilize immune cells in the reproductive tract which can help prevent and counter cancer.
Guntupalli and colleagues state in obstetrics & gynecology that ovarian cancer is one of the worst gynécological diseases and destroys over 22,000 women worldwide each year. Particularly because most cancers are not detected until they are advanced and difficult to treat.
The study team reports that oral contraceptives were previously linked to a reduced risk of ovarian cancer.
The American College of Obstetricians and Gynecologists states that IUDs and other condoms are extended and permanent and up to 20 times more successful for preventing pregnancy than birth control pills, patches or vaginal bands.
IUDs may have frequent menstrual or discomfort and serious bleeding side effects. Serious side effects are uncommon, but the instruments can fall out of the vagina, break the wall or trigger inflammatory pelvic diseases.
Guntupalli said, because IUDs are one of several contraceptive options, women must talk to their doctor about the right birth control in their special circumstances to make an informed decision.
“When a person has a higher risk of (IUD) ova cancer based on family background or other risk factors,” Guntupalli said. “Women’s loss of weight, daily ob / gyn visits and a non-sedentary lifestyle are other ways of reducing their threat.”
