Is adult pulmonary langerhans cell histiocytosis considered a form of cancer?

Yes: However, it's curious -- it can often regress when the tobacco smoke that is its growth factor is withdrawn. The whole "histiocytosis X" family are a proliferation of cells that are invasive by nature, so by definition there are no benign tumors arising from these cells. I wish you a speedy recovery.
