Can anyone help re. skin cancer

Hi

Not sure where to put this, but having had two lots of breast cancer and had brilliant help for everyone before, have now found I have basal cell skin cancer on good breast.

I have been prescribed Imiquimod (Aldara) and wonder if anyone else has come across this before. Used it for two nights and feel like I’m back on chemo - all fun.

Thanks and Cheers
