I have been diagnosed with bowens disease have had some treatment with solareze gel no success. had some areas cut and scopped out now been given efudix cream. Started on my leg Monday so now i am on my 4th day so far nothing has happened. I am only applying it to the worst marks on my lower leg and foot should i be applying it to the whole area that is affected and how long before it starts to work. If this leg is treated successfully how long before i can start on other parts of my body. I would be grateful for any information. thank you
