Abstract:
With earlier diagnosis and more effective treatments, more and more women are receiving fertility-preserving cancer therapy. Approximately 10% of breast and gynecological cancers occur in women under 40, and more than 5 000 French women under 45 develop breast cancer each year. While hormonal contraception is contra-indicated for women with a history of breast or endometrial cancer, it seems to have a protective effective in ovarian cancer. Although pregnancy is not contra-indicated after cancer, it must be planned in a timely manner, meaning that appropriate contraception is necessary in the meantime.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
