Imiquimod
"I'm using this for bcc. My areas were small to begin with. I am on week 6 and was instructed to use it 5 times a week. I've used a very small amount and I haven't had severe side effects. My lymph nodes have been swollen a few times. I make sure to wash the areas, let it dry, wash my hands and apply. I have always washed it off 8 hours later. I've also avoided getting in the sun. The areas haven't disappeared yet and I'm not sure what they should look like at this point."
