Does anyone know the regiman regarding ABVD treatments? My son has just gone through 6 mos of treatments and has had a month from that before going into a PT Scan next week Monday... He is saying that he thinks he still has his cancer...he says he thinks he still feels it in his back. The doctor is saying that he won't have radiation, so I don't know anything about what happens now. I've tried calling the doctor, but I keep missing her call back. Can someone tell me anything about this treatment?
