Is cancer passed from mother to child?
Patient: my mother found a lump on her breast at 32 years old right after and while nusring my now 17year old sister. obgyn did a physical exam and told her it was a cyst or a blocked duct. she then had another child and nursed her as well. 5 years later she was diagnosed with stage 2 ductalcatsonoma. she has since lost her battle with breast cancer almost 4 years ago. the issue now is that my now 15 year old sister has been diagnosed with osteoscarcoma of the spine. would having a baby and nursing with breast cancer have anything to do with the child developing cancer later in life? does the Brca2 cause bone cancer as well? all confusing for us right now. Doctor: Having a baby snd nursing them will not transfer the cancer.The baby will be at increased risk for cancer later on in life based on the fact t of family history.Osteosarcoma has never been linked to brca2 mutations .However li-fraumeni syndrome (p53 mutation) is know to cause breast cancers , sarcomas in the family.This syndrome is rare  and osteosarcomas can occur sporadical also without mutations.
