question: My daughter is a Hodgkins' Disease survivor--9 years since a successful transplant using her own cells.  She just delivered a baby 10 days ago, and baby has a lump in her left arm, exactly where my daughter had a tumorous cancer in her bones in her left arm and had surgery and radiation to remove the cancer.  Her baby has a lump in her arm exactly in the same spot that my daughter had her bone cancer in her left arm.  Is it possible that baby is having any cancer in her own left arm, since the lump is exactly where my daughter's cancer was in her own arm?
