The ends of the incision look infected and very painful. She should be rechecked right away for medication for pain and swelling and further antibiotics. She may need some parts opened and drained and flushed to help minimize the infection. If the tumor was cancerous and it was not completely removed, then there is a change the cells are angry and irritated and growing again from inflammation. Try to apply a warm compress and keep the area clean until you can get her in.
