I was diagnosed with renal cell carcanoma metastasis and had my right kidney removed Sept. of 2010. I was told that pawpaw was a great treatment for killing cancer cells in your body. I did do some research and it sounds great. Is there anyone who is currently on it who could give me some advise? It doesn't interfere with chemo or other drugs . I will ask my oncologist about it and hope he supports me in this as I feel it will help me. I am currently on sutent and have been for going on my 21st round( 2wks on 1 wk off, 25mg ). I have a tumor in my left sacrum and now have many nodules in my lungs that my doctoc says he can't do anything about as they are too small at this point,but they are so severely painfull. Sue
