Only high-dose VCD treatment accelerated the onset of persistent estrus relative to controls. Delay in VCD administration until after completion of mammary epithelial differentiation 3 months did not alter tumor formation despite acceleration of ovarian senescence. However, little is known about the precise pathogenesis of mammary fibroadenomas; thus further exploration of their etiology is warranted. Spontaneous mammary tumors occur with varying incidence in most strains of rats, including Sprague Dawley SD rats. However, no additional information regarding the hormone-responsiveness of these spontaneous tumors is available. In order to elucidate specific elements of the hormonal milieu that impact fibroadenoma formation in female SD rats, we chose to examine the effect of an ovary-intact, chemically-induced model of premature ovarian failure on mammary tumor occurrence.

Information here is taken from various booklets received by me and interpreted in a non-expert way — they should not be taken in any other context than my own — possibly muddle opinions. Chemotherapy is not a single thing. It is not a static process but a dynamic one which combines different drugs taken over a time period. Chemotherapy techniques are used to fight a range of cancers including multiple myeloma. There have been advances in the treatment of Myeloma over the past decade and the newer options are offering improvements in all of the areas above. There are always risks involved and these are weighed up against the benefits. Different pathways follow different routines and may or not involve a rest period between successive Chemotherapy treatments cycles.
