Do hormones cause tumors?

Estrogens, a group of female sex hormones, are known human carcinogens. Although these hormones have essential physiological roles in both females and males, they have also been associated with an increased risk of certain cancers.

Does progesterone increase breast size?

Raising progesterone levels

When taken as a pill, progesterone does increase breast size, and is fairly safely. However, it does so by stimulating the growth and development of milk-producing cells, an effect that most non-nursing women would wish to avoid.

Taking estrogen without progesterone increases your risk for cancer of the endometrium (the lining of the uterus). During your reproductive years, cells from your endometrium are shed during menstruation.
