Zygote is the diploid cell that results from the fertilization between an egg and a sperm. Etymology. Came from the Greek word âgametesâ meaning âhusbandâ and âgameteâ meaning âwife.â. Came from the Greek word âzygotosâ meaning âjoined or yoked or to yoke.
This is not causation, but facilitation after the fact. Stating that estrogen causes breast cancer is like saying fertilizer causes weeds. In a garden even weeds need some soil nutrients, and if these are completely removed, the weeds can't grow...but neither can the desired plants.
Before you start an estrogen treatment program, ask your doctor about the effects of estrogen on your body. While estrogen insufficiency can result in problems, estrogen levels that are too high (or prolonged exposure at the wrong times) can lead to menstrual disturbances, ovarian cysts, and breast cancer.
