STEVEN SHAPIRO, MD: I'd like to add something to that. We originally thought that UVB was the one that caused skin cancer, and we always remember B for bad. And later one, we found out that UVA also causes skin cancer, as well. So now that we know that both UVA and UVB cause skin cancer, they're both in tanning salons. And originally they used mostly UVB, they switched to UVA, and now we know that both rays cause skin cancer, and tanning salons contain both rays, so it can potentially cause skin cancer, as well.
SUSAN CINGARI: That brings me to my next question. Dr. Shapiro, what is the difference between UVA and UVB rays, then?
STEVEN SHAPIRO, MD: UVB is a much stronger radiation than UVA, and UVB is more absorbed by the epidermis than the deeper dermis where UVA is absorbed. In terms of your average daylight., around twelve noon is the strongest sun of the day, most of us know that, it's about 90% UVB at twelve noon. Earlier in the day it's more UVA, towards the end of the day it's UVA as well. So UVB is a much stronger radiation, however, UVA can cause skin cancer, as well.
MARIANO BUSSO, MD: Interestingly, they both product skin cancer. UVB is filtered from windows, whereas UVA not as much. And a perfect example of that is most skin cancers… take place on the left side of our body, because when we're driving, we have a lot of sun radiation from UVA rays. And so therefore, in Great Britain, it's on the right side.
SUSAN CINGARI: That's interestingly.
All right, Dr. Busso, how can we protect ourselves from burning, then? What's the best advice you can give us?
