乳腺增生病是最常見的乳房疾病,其發病率占乳腺疾病的首位。有報道認為,在城市婦女中,每20人就有1人可能在絕經前發現此病。乳腺增生病可發生於青春期後任何年齡的女性,但以30~50歲的中青年婦女最為常見。其主要臨床特征為乳房腫塊和乳房疼痛,一般常於月經前期加重,行經後減輕。由於乳腺增生病重的一小部分以後有發展成為乳腺癌的可能性,所以有人認為乳腺增生病為乳腺癌的“癌前病變”。
乳腺增生病既非腫瘤,亦非炎癥,而是乳腺導管和小葉在結構上的退行性和進行性變化。關於乳腺增生病的命名,由於國內外許多學者根據本病的病變特征及病理變化采用了不同的病名,所以其命名頗為混亂,如慢性纖維囊性乳腺病、乳腺良性上皮增生病、乳腺小葉增生癥、乳痛癥、乳腺腺病、乳腺結構不良癥等等。以上這些病名反映了本病病理變化的不同方面和不同程度,但其基本病理變化均為乳腺上皮細胞數目不正常及非生理性增加。為了避免這種命名上的混亂,使本病名稱趨於一致,1978年全國腫瘤防治研究辦公室將其定名為“乳腺增生病”。
不過,乳腺增生不一定會演變為乳癌,若經醫生檢查乳房沒有腫瘤,便毋須太擔心,只須定期檢查便可。
Gynecomastia (American English) or gynaecomastia (British English) is the development of abnormally large breasts on men. The term comes from the Greek gyne meaning "woman" and mastos meaning "breast". The condition can occur physiologically in neonates, in adolescents, and in the elderly. In adolescent boys, 90% of such cases the symptoms disappear in a matter of months to a few years at most. It is generally a result of an imbalance in hormones, although there are many different root causes. Gynecomastia is not simply a buildup of adipose tissue, but includes the development of glandular tissue as well.
