How Long Does It Take To Cure Prostate Cancer?

Dear Dr. My husband has cellulitis on both legs starting just above the ankles and halfway of his leg to the knee. His legs were like balloons and blistering red. After getting the antibiotic, the swelling has gone down some. He just discovered it last night. Today, the Nurse Practitioner gave him and antibiotic drip to start getting rid of the infection. My husband was taking Zytega for over a year and a half, and his oncologist changed his medicine to Bicalutamide 50 mg 3x a day. The N.P. took him off of the Bicalutamide until she sees him on Monday. He is also taking Furosemide 20 MG 1 tab 2x a day and Cephalexin 500 MG 4x day. He is being treated for prostate cancer. He is keeping his feet elevated above his heart as much as possible until Monday when he sees the N.P. Is there any way we can say how long it will be taking for him to get back to normal? And, I would like to ask advice about any immune system builders you might suggest he could take along with his meds. Thank You. My e-mail address is YYYY@YYYY
