What cancers are caused by hormones?
Hormone-related cancers, namely breast, endometrium, ovary, prostate, testis, thyroid and osteosarcoma, share a unique mechanism of carcinogenesis. Endogenous and exogenous hormones drive cell proliferation, and thus the opportunity for the accumulation of random genetic errors.
How does progesterone cause breast cancer?
Both the rapid actions and the transcriptional activity of PR-B contribute to breast cancer cell proliferation in response to progesterone. Progesterone/PR act in concert with mitogenic protein kinases and cell-cycle mediators to induce regulation of PR target genes and proliferative responses.

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.
