There have been some research studies looking to see if
estrogenHormone replacement therapy binds to neurofibromas, and they have found a small amount of
estrogenHormone replacement therapy receptors on the tumors. This means that theoretically
estrogenHormone replacement therapy could cause the neurofibroma to grow or get worse. Our pediatric neurologist does not recommend HRT in women with NF1 and I would have to agree. Continue the soy for now.
