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 daughters cancer was in her own arm?
Hi, Thanks for writing in. It is unlikely that your grand child is having a cancer at exactly the same area where your daughter once had a tumor. However, it is important to bring it to the notice of the pediatrician treating the baby and take a clinical opinion regarding the possibilities. Presently we have good imaging techniques and for a 10-day-old child, doing an ultrasound scan will help us know should there be any concern regarding a lump in the left arm. If there is a strong suspicion then doing an X-ray is also advised. It is more likely that the baby has some asymmetry of arms and this can be verified by clinical examination itself. Please do not worry.
