After Aldara Treatment

Hi,

I found that a large scaly place on my right cheek was Squamous Cell Cancer on May 8th.  Because of the large size my doctor wanted to try Aldara for one month.  I applied it three time a week.  I stopped on June 13th and visited the doctor on the 19th.  He was well pleased with how it looked.  It was very red with a large tan scab down the middle.  He told me to keep it clean with soap and water.  The area is dry and still scaly, most of the scab is gone, but the red area is spreading.  Has anyone here used this for Squamous Cell?  Should this red area be getting larger? 

Thank you for reading this.  I look forward to some feedback.
