Estrogen



Estrogen is probably the most widely known and discussed of all hormones. The term "estrogen" actually refers to any of a group of chemically similar hormones; estrogenic hormones are sometimes mistakenly referred to as exclusively female hormones when in fact both men and women produce them. However, the role estrogen plays in men is not entirely clear.
To understand the roles estrogens play in women, it is important to understand something about hormones in general. Hormones are vital chemical substances in humans and animals. Often referred to as "chemical messengers," hormones carry information and instructions from one group of cells to another. In the human body, hormones influence almost every cell, organ and function. They regulate our growth, development, metabolism, tissue function, sexual function, reproduction, the way our bodies use food, the reaction of our bodies to emergencies and even our moods.
The estrogenic hormones are uniquely responsible for the growth and development of female sexual characteristics and reproduction in both humans and animals. The term "estrogen" includes a group of chemically similar hormones: estrone, estradiol (the most abundant in women of reproductive age) and estriol. Overall, estrogen is produced in the ovaries, adrenal glands and fat tissues. More specifically, the estradiol and estrone forms are produced primarily in the ovaries in premenopausal women, while estriol is produced by the placenta during pregnancy.
In women, estrogen circulates in the bloodstream and binds to estrogen receptors on cells in targeted tissues, affecting not only the breasts and uterus, but also the brain, bone, liver, heart and other tissues.
Estrogen controls growth of the uterine lining during the first part of the menstrual cycle, causes changes in the breasts during adolescence and pregnancy and regulates various other metabolic processes, including bone growth and cholesterollevels.
Under the age of 50 or pre menopause Estrogen is what can make the Cancer come back somewhere else, great idea to take the estrogen strippers, I believe we have to take them for 5 years, although can vary.

"Hard nipples" - areola or nipple skin

Someone once wrote"... when i get really cold, or get goosebumbs all over my body, the whole things really scrunch up, like, my entire areola scrunches itself up into a wrinkled little mound. it looks really weird and ugly, and i haven't ever seen other people's breasts do it. what is wrong with my areola/nipples??" The answer: Well nothing is wrong. This is what my areola does too. It's a normal reaction to the coldness or to irritation / stimulation. The little muscles in the areola do a similar goosebump thing as your other skin can do. People often call this phenomenon "hard nipples". Also note that skin on areola has less feeling or sensation to it than other areas of your body. If the areola was very sensitive, then breastfeeding would probably be quite uncomfortable because the baby pulls and tugs it! The nipples are sensitive but the sensitivity changes with hormonal changes, such as occur at mestrual cycle or pregnancy. Also this v...

Kate Jackson Breast Cancer a flash back

THE MOST MOMENTOUS CHANGE IN Kate Jackson's life began early one morning in January 1987, during her fourth season on the hit TV series Scarecrow and Mrs. King. After a phone call informed her that the show's taping was canceled because costar Bruce Boxleitner had the flu, Jackson went back to sleep. When she woke several hours later, "It was out of the blue, but perfectly clear," she recalls. "I sat up in bed and literally said, 'You have to have a mammogram.' " She did, and two days later a biopsy confirmed her vague fears: A minute growth found in her left breast was determined to be malignant. "I was forced to face, squared up, my own mortality," says Jackson. "I had to decide whether I wanted to live or to die. And if you choose life, as I did, it's never the same." For three TV seasons 16 years ago, she was famous as Sabrina Duncan, a girl-next-door gone glamorous and the character critics dubbed the brainiest o...

The four stages of breast development

Stage 4 shows fully mature breasts. (Illustration by GGS Information Services.) period begins. Usually these signs are accompanied by the appearance of pubic hair and hair under the arms. Once ovulation and  menstruation  begin, the maturing of the breasts begins with the formation of secretory glands at the end of the milk ducts. The breasts and duct system continue to grow and mature with the development of many glands and lobules. The rate at which breasts grow varies significantly and is different for each young woman. Breast development occurs in five stages: Stage One: In preadolescence, the breasts are flat and only the tip of the nipple is raised. Stage Two: Buds appear, breast and nipple are raised, fat tissue begins to form and the areola (dark area of skin that ...
