Since the birth of my son 10 months ago, I have developed Rosacea. I also have a history of basal cell (2 removed on my face with MOHS). I would like to prevent more or catch them early to keep facial defects to a minimum. My doctor told me both spots were Rosacea, and was wrong when I insisted on a biopsy. I am checked every 2-3 months, but I still find the spots myself. How can I tell the difference between Rosacea and BCC? I use doxycycline and Metrogel. I have not used laser for fear of camouflaging BCC.
