Post-menopausal Women with Breast Cancer

since both factors are known to be associated with increased and earlier development. The same factors may therefore be responsible for the accompanying delay in the menopause. Tanner (1962) suggests that the pituitary gland may be involved in both the change in age of menarche and of menopause, and this is made more plausible by the fact that adolescence is not only reached earlier than previously but that boys and girls are also bigger than before. Since an earlier age of menarche accompanies an earlier and increased development at adolescence it seems possible that a later age of menopause may accompany a delayed or decreased rate of "physiological degeneration "-that is, decreased rate of ageing. The answer to this problem, however, requires further research.
