Although several fat studies in modern years have linked the use of hormone treatment after menopause with an increased endanger of boob cancer, the authors of a new examination claim the evidence is too limited to confirm the connection.

Together, the results of these studies found overall an increased chance of mamma cancer amidst women who Euphemistic pre-owned the combination form of hormone remedial programme with both estrogen and progesterone.
