Skin Cancer Prevention Tips From Dr. Moy

STUDIO CITY (CBSLA.com) — Scientist, researcher, dermatologist and cosmetic surgeon Dr. Ronald L. Moy visited KCAL9 Tuesday to discuss pre-cancers.

These risky patches of sun damaged skin are the last-ditch warning of the deadly cancer plaguing 1 in 5 Americans.

How pre-cancers develop:

• Frequent exposure UV rays increases the risk of developing pre-cancers.

• A family history of skin cancer can also make one more prone to developing pre-cancers.

• Typically, pre-cancers appear as either a red, scaly bump or an area of persistent scaliness.

How to prevent pre-cancers:

• One can prevent the development of pre-cancers by diligently applying a broad spectrum sunscreen of at least SPF 30 daily.

• Using creams with DNA repair enzymes also work to minimize sun damage and prevent the development of pre-cancers.

What are some methods for removing pre-cancers before they develop into cancer?

• In the event a pre-cancer has already developed, there are several options to remove them and stop their advance into actual cancer. These options include freezing the lesion using Cryotherapy, the application of topical chemotherapy, laser resurfacing, the use of topical DNA Repair Enzyme creams, and even eating a low-fat diet.

• Luckily, there are many preventative measures that can be taken to protect against pre-cancers. These include applying a broad spectrum sunscreen every day, wearing hats and other protective clothing, and if possible, avoiding the sun's rays mid-day, when they are most dangerous.
