I have skin flaking from my nose. I have had skin cancers dealt with. How do I stop flaking skin?

More skin cancer? I wonder if the flaking skin is abnormal or possibly a new skin cancer. My advice would be to show this area to your friendly dermatologist.
Seb Derm. Seborrheic dermatitis is thought to be due to a combination of an over production of skin oil and irritation from a yeast called malassezia. Seborrheic dermatitis appears to run in families. Stress, fatigue, weather extremes, oily skin, infrequent shampoos or skin cleaning, use of lotions that contain alcohol, skin disorders (such as acne), or obesity may increase the risk.
