What is the relationship between fertility and cancer in women?

NEW YORK (Reuters Health) – A new study reveals that women at risk for cancer, particularly cancers of the uterus and ovary, are 18% more likely to have cancer of infertility or fertility

This may be due to the fact that women who undergo IVF experience have received powerful medications that alter their hormone levels. Infertile women may suffer from genetic problems that increase the risk of cancer, as well as non-reproduction.

The researchers tracked the situation of more than 64,000 women with fertility problems for nearly four years, comparing the medical records of 3.1 million fertile women.

The results showed that 2% of infertile women were diagnosed with cancer at that time, compared to only 1.7% of women without fertility problems.

The study, published in the journal Human Reproduction, suggests that infertile women may have cancer, whether they have been vaccinated or not.

Having children can be the solution for women who want to reduce the risk of cancer because the reproductive process affects the hormones associated with certain types of cancer.

"Because of the low overall incidence of cancer in these women, one in every 49 infertile women will have cancer during pregnancy, period of follow-up, versus one in 59 non-infertile women."
