Hormone of contraceptive can bring out breast cancer The expert reminds carefully to use the hormone treatment
A few days ago, published two reports finished by American and Austrian researcher respectively on Britain's scientific magazine " Nature ", they study independently but has obtained unanimous result, namely contraceptive and hormone substitute estrogen, progestogen in the treatment and get in touch closely through broken bone cell factor and breast cancer of splitting up. This magazine also published a discovery of the researchers of cancer of Princess Margaret Hospital of Hong Kong before, indicate ovarian hormone progesterone has born the important role in changing the stem cell of mammary gland.
Artificial synthesis progestogen used in the contraceptive course blindly cause the morbidity of breast cancer to rise - carry news through to the end " to use the hormone treatment on earth? The daughter says recently my temper is more and more discredited, I suspect whether oneself is to climacteric too, friend say go hospital turn on, supplement estrogen just by some medicine, but I surf the Net consult, say someone by hormone in place of treatment can have lasted breast cancer,say someone can,it there is be a lot of evidence behind, who should believe? " Ms. Song says disconsolately.
Compare abroad, because the proportions of personnel of regarding hormone as the means of improving looks etc. at home are relatively low, so find data correlated to breast cancer are changed will be less. It is reported, involutional women are in the body progestogen drops, estrogen rises, mostly adopt hormone to treat in place of the treatment, the increasingly many data make such a crowd of Ms. Song at a loss. And the recent report says especially, the hormone, will all be through RANKL (the factor of splitting up of broken bone cell) Get in touch with breast cancer closely, is that really like this?
Progestogen " Instigate " RANKL " gives a piece of bad advice "
"If the family has rheumatic arthritis or osteoporosis patients, must have heard the name of RANKL, traditional Chinese and western medicine will mention, what a lot of people do not know is, it is closely related to development of mammary gland. " The teacher-training university students in the capital order endocrine beautiful duckweed associate professor Yang of research room of scientific institute's reproduction to explain, RANKL is a kind of protein existing in the skeleton, are called factor of splitting up of the broken bone cell, express and become abnormal or cross and express, can cause a series of bone disease, such as causing osseously to run off to cause osteoporosis, will also cause rheumatic arthritis, the ill arthritis of silver bits.
Someone make study ever, find if the mouse during gestation lacks RANKL, then the mouse can't secrete the milk. "But is not clear what kind a mechanism RANKL is specifically with the growth of breast cancer cells in. " Yang XiuPing says to the reporter.
Beautiful duckweed Yang explain, these two different laboratories find respectively RANKL express in the mammary gland cells of the mouse too, control the morbidity that induces breast cancer produced from progesterone after explaining RANKL.
