Sphynx Cat

Hi there. hope everyone is in good spirits! I have been gifted this Sphynx cat that is a rare breed of cat known for its lack of a coat. Now the problem is that it started having some health issues which I think are because of its lack of hair. Either this or the cat has caught some common feline diseases. Where can I get it immunized like other breeds? Also tell me if there’s any possibility of cancer?? I’m really concerned. Help put guys!!
