Contraceptives to prevent ovarian cancer, women using birth control pills can reduce the risk of ovarian cancer. The researchers imagine this is due to hormonal changes and ovulation was inhibited. But recent study showed, in which the causal relationship between the complex than imagined. For example, according to Stanford University School of Medicine Dr. Alice S Whittemore, the efficacy of oral contraceptives may decrease with age.
Researchers hope to determine the past 30 years ovarian cancer incidence can be attributed to the decline in more women using oral contraceptives, and decreased the amount of child birth. Studies show that women under the age of 50 can really make the such a positive assessment. And women over 50 years of age the proportion of ovarian cancer than expected.

Of 767 ovarian cancer patients and 1,367 healthy women, studies also reveal inflammation of ovarian epithelial cells can induce cancer risk. When these organizations inflammation, resulting in some of the material and the role of other factors that can lead to cancer. These substances such as cytokines (Cytokines) [a cell signal sub-sub-(cell-signaling molecules)], prostaglandin (hormone similar to the mixed material, have a greater impact on the human body.) Karolinska Institute, Stockholm, and Dr. Ingemar Persson Dr. Tomas Riman, the study revealed the protective effect of oral contraceptives, a new mechanism. Also confirmed that ovarian hormones and inflammation is the direct cause of ovarian cancer.
Contraceptives to prevent ovarian cancer.
