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.
This theory states that 15% of cancers are caused by viruses. One example is HPV, which causes cervical cancer i.e. cancer of the cervix in women. The virus is lysogenic and it inserts a destructive gene into the tumor suppressor T53 gene. This allows a mutated oncogene to cause a cell to become cancerous.his theory states that 15% of cancers are caused by viruses.
