Hi,Dear.Thanks for the query to HCM virtual Clinic.
I am Dr.Savaskar attending on your query.I studied your query and understood your health concerns about your Sister.
Cause of lumps in Neck-
The neck lumps you have are of
thyroid origin, whether primary and with secondary,needs to be worked out by FNAC,FDG PET/CATS SCan study.YOUR sister appears to suffer from MEN-muliple endocrinal Neoplasia Syndrome, and hence she has all these tumors of various glands as salivary/thyroid/breast etc.and is due to genetic/ familial reason.
This is how you plan treatment with your doctor.
Hope this would resolve your query.
Write good review and hit thanks after reading this reply.
Welcome for any further query to HCM and to ME.
Wishing you early recovery.
Dr.Savaksar M.N.
