Yaz side effects in organs

The most controversial adverse effect of yaz is the effect it has in oncologic system. Many studies have been carried on that but even the World Health Organization (WHO) hasn’t totally agreed about links between breast cancer, cervical adenocarcinoma and use of oral contraceptives. They find it difficult to give a certain response about it because many other factors impact on, at the same time. Although according to WHO there does exist a weak association between a long use of oral contraceptive and breast cancer in women under 35 and up 45 years old. While the studies result in a contrary regarding to the yaz use and cervix carcinoma.

Taking estrogen will obviously impact in cardiovascular system. Studies showed that low doses of it have negligible effect in heart function especially in women who do not smoke.

An Italian study showed that risk of hepatocellular carcinoma is higher in women who use oral contraceptive compared to whom who never use them. However this is considered not important in US and West.

Genitourinary changes are related to menstrual disorders, which can lead even to a permanent suppression of menstrual cycle.

Cases of ocular changes have been known too. In worst ones it may cause partial or total loss of vision.

To finish, yaz side effects include hypersensitivity and upper respiratory infection.
