My grandfather is 91 years old. He is suffering from mouth cancer (large wound over lips) from last 3 months. From last night I saw little few insects on wound. He is feeling pain. Me and my family care him .I consult so many doctor but not find any recovery. Here there are two question in my mind 1.is any possibility that he get well soon or not. 2.as we care him from last few month .Any chance that me and my family infected with such disease ?If yes than what are the symptoms so we know we are infected .Is any check up to know that we are infected. Please advised me.
