If you Radiation Oncologist recommended this, I think it's a great idea. I was seeing an NP regularly before my diagnoses, she felt it would be inappropriate to treat me once my I started chemo. I did see through out the 3 weeks of pre diagnosis testing to help manage my anxiety, and its effects on my body.
With my oncologist ok, I do incorporate alternative therapies, such as supplements,herbs, massage and energy work into my at home care. I would see NP if I could find one who could work with someone on Chemo.
