Hi Bagpuss,
7. May 1999. A landmark study was published in the prestigious British medical journal, The Lancet. This study showed that pre-menopausal women with fibrocystic breast disease have an almost 6-fold higher risk of
future breast cancer. This study firmly refutes the advice of some doctors who have said that fibrocystic carries no increased risk. In all, there are now over 30 published medical and scientific research
articles showing a connection between fibrocystic and increased breast cancer risk. (Lancet 1999 May 22;353(9166):1742-5 "Risk of breast cancer in women with palpable breast cysts: a prospective study." Edinburgh Breast Group. Dixon JM, McDonald C, Elton RA, Miller WR Edinburgh Breast Unit, Western General Hospital, UK.")

Thanks Rockhen, it won't come to much, but I am working on the principle that it all adds up.
