Cancer Research: More than 250,000 people have studied data showing that oral contraceptives can prevent ovarian and endometrial cancers

Ovarian cancer and endometrial cancer are the three most common types of gynaecological cancer, which is very harmful to women's health.
cancer is more common than ovarian cancer, and the mortality rate is lower because it is easy to detect early and the symptoms are more pronounced.
, however, ovarian cancer is one of the deadliest cancers in women and is usually only detected when it spreads to other areas.
, a study published in the journal Lancer Research showed that oral contraceptives can prevent ovarian and endometrial cancers.
the drug is stopped, the protective effect will continue for decades.
study, researchers looked at the short- and long-term relationship between oral contraceptives and breast, ovarian and endometrial cancers in more than 250,000 people.
study collected 256,661 women from the UK Biobank database from 1939 to 1970.
researchers collected self-reported data (including lifestyle and medical history) from participants and cancer diagnosis information in national registries until March 2019.
the risk of developing oral contraceptives and cancer using Logistic and Cox regression analysis.
found that women who had used oral contraceptives had a much lower risk of ovarian and endometrial cancer than those who had never used them, and that the longer they used them, the stronger the association.
15 years after the pill was deactivation, the risk of ovarian and endometrial cancer was reduced by about 50 percent.
even 30-35 years after the drug was stopped, the pill still protects against ovarian and endometrial cancers.
In different age of follow-up, oral contraceptives and breast, ovarian, endometrial cancer risk than researchers further found that the age of follow-up is limited to 55 years of age, oral contraceptives for women with an increased risk of breast cancer, but only slightly increased in a short period of time, after a few years of retirement this risk is not present.
, that is, the risk of breast cancer in women on oral contraceptives was not significant throughout the time period.
, oral contraceptives can significantly reduce a woman's risk of ovarian and endometrial cancer, which has a limited impact on the lifetime risk of breast cancer.
that oral contraceptives protect against ovarian and endometrial cancers for up to 30-35 years after suspension.
, the use of oral contraceptives and the risk of breast cancer depend on time and age.
