My Husband Was Just Diagnosed With Sarcoma Cancer Of The

My husband was just diagnosed with sarcoma cancer of the voice box and lymph node. This could be the HPV virus so I am assuming I have this as well? I am regularly screened with a pap test yearly. What should I do right now and is it safe for my husband and I to continue to have sex. Is there something I should be doing to prevent cancer in me?
I am also wondering about the chance of him surviving this.
