Does IVF increase the risk of cancers?

Thought I need to share this. Science says, cancer of the uterus is more common in women who have not had children and cancer of the cervix is less common. However, fertility drugs cause neither of these cancers. Nor is there the slightest evidence that there is an increased risk of cancer of the breast following IVF.
In some women, there is undoubtedly a genetic factor. Ovarian cancer is about twice as common in women who have not had children. According to most studies, it is more common in women who have delayed child-bearing. Women who give birth before the age of 25 are less likely to get ovarian cancer and with each five-year delay, the chance of developing it increases by about ten per cent. Different studies show different associations with miscarriage; some report the risk is higher after a miscarriage, but others suggest it may be lower.
Women who have an early menopause (before the age of 45) are at lower risk than those who go through the menopause after they are 50. Women who use the pill for longer than five years seem to reduce their risk of ovarian cancer by around 50 per cent. It is unclear whether women on hormone replacement therapy (HRT) are at greater risk. Infertile women are about twice as likely to develop ovarian cancer. Interestingly, this effect is also seen in women married to infertile men.
There is no clear evidence of an increased risk of ovarian cancer in women having IVF treatment or fertility injections, compared with women who are infertile. There is some doubt about an increased risk in women who are given these drugs but who do not become pregnant. Unexplained infertility in some women may occasionally be due to some ovarian abnormality – which could possibly include some very early form of ovarian pre-cancer.
