Study Summary
The purpose of this proposal is to improve our understanding of the role of tryptophan and serotonin in hot flashes. The main hypothesis is that alterations in tryptophan and serotonin levels are involved in the induction of hot flashes in women with breast cancer and genetic variations in the serotonin receptors and transporters also play a role.
Primary Outcome
Mean serum tryptophan levels (blood draw) at the end of the nadir period.
