Can cervical cancer have any effect on an unborn child?

Not likely. It should not have an effect on the unborn child, or a newborn child, but if it was not removed before pregnancy, it can grow, and affect the mother due to the time allowed to spread. If it is localized, removed, and a pregnancy occurs before the cevical epithelium grows back, the cervix might be incompetant, resulting in a possible loss of the fetus. Best to be treated before pregnancy.
