3. Low Progesterone during Pregnancy Can Lead to a Miscarriage. Low progesterone levels can cause complications during a pregnancy. In the early stages, it can be a sign of an ectopic pregnancy, or an indication that there is a great risk of miscarriage. If progesterone levels are below 6ng/ml during the 6th gestational week, the pregnancy is usually not viable.
Certain HPV types are classified as high-risk because they lead to abnormal cell changes and can cause genital cancers: cervical cancer as well as cancer of the vulva, anus, and penis. In fact, researchers say that virtually all cervical cancers -- more than 99% -- are caused by these high-risk HPV viruses. The most common of the high-risk strains of HPV are types 16 and 18, which cause about 70% of all cervical cancers. If the body clears the infection, the cervical cells return to normal. But if the body doesn't clear the infection, the cells in the cervix can continue to change abnormally.
Unlike some other cancers, cervical cancer is not thought to be passed down through family genes. In fact, those 7 types of HPV are responsible for about 90% of cervical cancer cases. Itâs believed that many women with cervical cancer were likely exposed to cancer-causing HPV types in their teens and 20s.
