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.
The types of HPV that cause warts do not usually cause cell changes that develop into cancer. At least 12 types of HPV are considered high risk for cancer of the cervix. Two of these types (HPV 16 and HPV 18) cause about 7 out of 10 cancers of the cervix (70%). You are more at risk of developing pre cancerous cervical cells or cervical cancer if you have persistent infections with high risk types of HPV.
