Progesterone Breast Growth . Men and women both have mammary glands so what's the difference well we saw that they'd have the ducts and the differences in size but the big difference is that when do mammary glands develop they typically develop during puberty so before puberty they they're pretty much identical in boys and girls before they develop they undergo puberty so they have the basic structure of undeveloped mammary gland but it's the changes in puberty that caused the development of mammary glands now what happens is that you have an increase in pro estrogens and progestogens in p when you start off the menstrual cycle and um and a girl has her first menarche her first menstrual cycle that's when you start to have that cyclical waves of estrogens and progesterone but what happens in male puberty is that you have increased levels of androgens you do have some estrogens and aromatase as well but this is things like you'll get increased high levels of andr...
How To Test may detect breast cancer earlier
Scientists have developed a blood test that could help to detect breast cancer 'at a very early stage'.
Scientists have developed a blood test that could help to detect breast cancer 'at a very early stage'.
According to the international research team, it has developed an 'ultra-sensitive' test that is 200 - 1,000 times more sensitive than existing tests.
In a study involving 250 women with breast cancer and 95 controls, the blood test successfully detected 95% of cancers.
The test works by detecting very small changes in concentrations of protein in the blood. The researchers believe that with changes, it could also be used to detect other types of cancer such as prostate and ovarian cancer.
"Our pilot studies show that using blood samples, breast cancer and several other types of cancers can be detected with much better sensitivity and specificity. This may allow new, less intrusive, safer and much less expensive approaches for the early diagnosis of cancer, for distinguishing malignant and benign cancers and for monitoring cancer therapy", said lead researcher, Prof Jasminka Godovac-Zimmermann of University College London.
Details of these findings are published in the Journal of Proteomic Research.
