I was just diagnosed with breast cancer and needed to discontinue HRT. I would like to know how long before these drugs are out of my system. I was taking 1 mg of estradiol once per day and 100 mg of progesterone once every other day. Thank you.

The estradiol is the one you have to worry about and its out of your body quickly, the half life is 1-2 hrs so it would be gone in around 10 hrs.
