Narrator: This is Science Today. Melanoma, a malignant skin cancer, is fast becoming more common. Dr. Stanley Leong of the University of California, San Francisco says one of the reasons may be the fact that the ozone is becoming depleted.
Leong: For sure, melanoma is approaching an epidemic level both in the United States as well as the rest of the world. It is estimated by two thousand one out of Americans will be diagnosed of melanoma.
Narrator: The good news is more often than not, patients have thin level melanoma, which is easier to treat.
Leong: If a thin melanoma is removed in general, the patient can enjoy a very remarkable cure rate, in fact, over 90 to 95 percent of the time, if it's a thin melanoma, the patient can actually do very well.
Narrator: So looking out for changes in the mole is key.
Leong: If there are any changes in the mole one should bring this to the attention of his or her physician and have it biopsied and analyzed.
