i'm sorry to hear about your husband's skin cancer. that can certainly be a scary experience and you're wise to keep a close watch on his skin from now on. the cracking at the corner of your husband's mouth probably is not cancer but since he's had a skin cancer once it would be a good idea to get it checked out by a health care provider. often cracking at the corner of the mouth is a symptom of perleche or angular chelitis. this can be caused by a fungus (which can be treated by your health care provider) or by a vitamin b deficiency. however the symptom you're describing could be caused by many things including yes a cancer. that's why it would be best for your husband to be examined by your primary care provider. he or she can diagnose the problem and treat it accordingly. good luck to you!
