Throughout an individual's lifetime, the human body is exposed to many different chemical compounds, including xenoestrogens (XEs) that can be found in the environment, food, air, cosmetics and other substances, which have a positive or negative impact on their health and lifestyle VSports手机版. Whereas high-risk human papillomavirus (HR-HPV) is necessary but not sufficient for full malignant cervical cell transformation, other compounds such as estrogens and XEs may be risk factors for cervical cancer (CC) development. The causes and effects of some diseases such as cancer, cardiovascular, metabolic or immune system disorders are partly due to signaling pathways in response to estrogens. XEs are a vast group of natural and synthetic compounds, behaving like estrogens, that have been studied over the recent years and which may interact with estrogen receptors. The major problem with XEs is the difficulty in studying the mechanism of such complex substances as well as investigating the influences of some of the compounds (dose-dependent) over time. The impact of XEs on CC is variable, with no direct comparison between in vitro studies and in vivo XEs action. .
