Comment

• "Malignancies among women who gave birth after in vitro fertilization" - Bengt Kallen,  Tornblad Institute, University of Lund, Lund, Sweden
   
  "We studied women who had undergone in vitro fertilization, the majority treated with fertility drugs. There was no general increased risk of (mainly premenopausal) cancer among these women  when followed in the national cancer register. There was an increased risk for ovarian cancer but that was seen also before treatment and may be due to ovarian pathology which increased the risk both for infertility and for cancer. Our study indicates that in vitro fertilization does not increase cancer risk in the woman"
