Assessment of Ovarian Reserve in Female Cancer Survivors

Chemotherapy can damage the ovaries and cause premature menopause. In women treated before the age of 40 years, menopause does not usually occur. We have very little information about the impact of chemotherapy on ovarian function in this particular group of women. In this study, we will check hormone blood tests and ultrasound tests of the ovaries to measure the reserve of eggs left in the ovaries after treatment in young survivors of breast cancer and childhood cancer. We will do the same tests in our comparison group. We can use these results to estimate the reduction in fertility in young cancer survivors.
