微博热传，每天戴文胸超过12小时，患乳腺癌几率高出21倍。专家说，致癌说过于惊悚，但文胸阻碍血液循环，确实不宜久戴。

Microblogging heat transfer,Bras for more than 12 hours a day,21 times higher risk of breast cancer.Experts say,Carcinogenic said too scary,But the bra hinder the circulation of the blood,Don't wear too long indeed.

　　微博还提到，那些晚上也不摘文胸的女性，患癌可能性要高出100多倍。因为胸罩卡紧胸部会影响淋巴液的正常流通，久而久之使乳腺的正常细胞发生癌变。

Weibo also mentioned,Women who also don't pick a bra at night,More than 100 times more likely to develop cancer.Because a bra tight chest will affect the normal lymph circulation,As time passes makes normal cells occur cancer of breast.

　　武汉天美医院乳腺病专家李永汉昨日说，劣质的文胸材料，过紧的尺码或太长时间佩戴，会导致乳腺增生等疾病。理论上，不恰当地佩戴文胸，确实有可能增加患乳腺癌风险，但这种可能性无法量化，更不可能高出21倍甚至100多倍。

　　李永汉说，引起乳腺癌的因素是多方面的，包括遗传因素、晚婚晚育、不生孩子或不哺乳、流产多或雌激素水平过高等。

Li Yonghan said,There are many causes of breast cancer,Including genetic factors,/Late childbirth of marry at a mature age/Don't have children or lactation/Abortion more or ever higher levels of estrogen.

　　他发现，为了追求乳房外观的漂亮，许多初高中生早早开始佩戴文胸。他说，上下胸围相差16厘米以上，才需要佩戴文胸。青春期女孩仍在生长发育期间，过早戴文胸既不利于健康，也阻碍了乳房自然生长。即便是成年女性，每天佩戴文胸的时间也宜短不宜长，最好是出门佩戴，回到家就摘下。(记者武叶 通讯员杨娜)
