  This is a good (but difficult) question.
  
  I’ve done some research in various cancer resources and this one seems quite useful if you want to know more (although it is very detailed) : http://www.cancer.net/patient/Coping/Emotional+and+Physical+Matters/Sexual+and+Reproductive+Health/Pregnancy+and+Cancer
  
  It is very rare for a mother to give cancer to her baby. Some cancers do spread in the blood stream and so can get to the placenta, causing cancer there, but they very rarely reach the baby in the womb directly. Unfortunately if the baby did get cancer it would not cure the mother – they would both have cancer 🙁
