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...

Mastectomy Drain Breast Cancer Treatment

The  purpose of drains after mastectomy  is to drain away the fluid that can gather in the armpit region or around the scar on the chest wall. Some people after mastectomy also find that fluid gathers around the shoulder blade area on their back - this seems more common if the muscle from the back has been used for  breast reconstruction  at the time the mastectomy was done. When mastectomy is done - and especially if the lymph nodes are removed from the axilla or armpit - then there is a lot of tissue fluid and lymph fluid left with no where to go. This fluid normally flows through the lymph channels but if they are cut then it can escape into the normal skin and muscle tissues. Your surgeon will place drains under your skin after mastectomy. These drains gather up the fluid and remove it to a bottle (or bottles) that you carry around with you. Some people use a  belt clip to attach the drain  to their waistband - making them more mobile. Others car...

Pancreatic Cancer breakthrough

Published Today By  Ana Sandoiu Fact checked  by Jasmin Collier New research now published in the  Journal of Natural Products  shows that a vine compound is highly effective in the fight against treatment-resistant pancreatic cancer cells. #cancer #cells #pancreaticcancer #breakthrough #natural #journalofnaruralproducts #cure #survivor #iamstillawoman #Anasandiou #jasmincollier A type of rainforest vine may hold the key to effective cancer treatments.  Pancreatic cancer  is notoriously difficult to treat, and the condition has a poor outlook. According to the American Cancer Society (ACS), the 5-year survival rate for people with early-stage exocrine pancreatic cancer is  12–14 percent . A  new study  explains why that is and offers a potential solution. Gerhard Bringmann, a professor of organic chemistry at the Julius-Maximilians-Universität Würzburg in Germany.  Specifically, human pancreatic ...
