Women seeking infertility treatment can be reassured that in vitro fertilisation is unlikely to increase their risk of breast or gynaecological cancers, say the authors of a large study of Israeli women.
Data from nearly 70,000 patients who had IVF treatment from 1994 to 2011 and a further 20,000 who sought treatment but didn?t have IVF showed no difference in their chances of being diagnosed with breast or endometrial cancer.
The risk of both in situ and invasive cervical cancer was actually reduced in women receiving IVF, the authors said.
But there were marginally higher odds of developing ovarian cancer among the IVF group, with that risk rising slightly with increased rounds of treatment.
However the authors said that due to the rarity of ovarian cancer, with only 45 cases recorded among the study participants, it was hard to link it compellingly to IVF treatment.
Previous research on IVF and cancer has produced mixed results with one recent Australian study claiming early IVF ups breast cancer risk. But other studies have found little evidence of a link.
