In medicine, there is perhaps nothing as low-tech as a skin cancer examination. Doctors simply use their naked eyes to scan patients' bodies for signs of trouble. But a new high-tech method that enhances the ability of the human eye to identify the most serious form of skin cancer is starting to pop up in some dermatologists' offices, including at least three Los Angeles offices. Called digital microscopy, the technology could benefit individuals with an above-average risk of developing melanoma.

Researchers Tuesday began the first experiments using human gene therapy to treat cancer, the National Institutes of Health announced. A 29-year-old woman and a 42-year-old man with advanced melanoma, a potentially lethal form of skin cancer, received transfusions of special cancer-killing cells removed from their own tumors, along with a gene that has been coded to produce a powerful anti-tumor toxin. The hope is that the mixture will destroy the patients' cancers.

In a bid to make cancer immunotherapy more effective, researchers report they have succeeded in halting the progress of aggressive melanoma in its tracks - at least briefly - in seven patients treated with an army of cloned cancer-fighting immune cells. In one of those patients, the treatment resulted in complete remission of his metastatic melanoma and evidence that his immune system stands ready to fight any return of the cancer after three years. The study, published Monday in the Proceedings of the National Academies of Science, contributes to hopes that a tumor-fighting strategy called immunotherapy can slow, halt or even reverse the growth of a range of cancers - and do so with fewer dangerous side effects.

Two new drugs can significantly increase survival in patients with metastatic melanoma, the advanced and generally lethal form of skin cancer, researchers reported. Results were so dramatic in a trial of one of the drugs that the study was halted early, researchers reported Sunday at a Chicago meeting of the American Society of Clinical Oncology. Studies on both drugs were published online by the New England Journal of Medicine. Melanoma is among the most common cancers in the United States.

Scientists have identified a defective gene that appears to cause an inherited tendency to the deadly skin cancer melanoma and may also play a role in non-inherited melanoma. In its normal state, the gene acts as a brake on cancer. But people who inherit a defective version apparently lose part of the protection, making them unusually vulnerable to melanoma, the researchers said. About 32,000 melanoma cases and nearly 7,000 melanoma deaths are expected in the United States this year.

African Americans are three times more likely than whites to be diagnosed with skin cancer when it is already in an advanced and possibly fatal stage, according to a study in Miami released Monday. Researchers pointed to a lack of public awareness about the risks of skin cancer for African Americans as well as Latinos, who are nearly two times more likely than whites to have a late-stage diagnosis. The research focused on melanoma, the deadliest form of skin cancer.

A new potential danger for sun worshipers--eye cancer--has been identified by medical researchers. And they urge people in southern climates who spend a great deal of time outdoors to wear hats, visors and good quality sunglasses that cut out at least 99% of ultraviolet rays.

“Tanning kills,” warns Travis Kidner, a skin cancer surgeon, in a recent Times Op-Ed article advising against tanning beds. Still, tanning salons continue to attract customers, many of whom are young, white women undeterred by the dangerous risks. Science Now's Karen Kaplan reported : “The latest evidence comes from researchers at the Centers for Disease Control and Prevention. In a research letter published online Monday by JAMA Internal Medicine, they report that 29.3% of white high school girls went to an indoor tanning parlor at least once a year, and 16.7% went 'frequently' -- at least 10 times in a 12-month period.

A biopsy of a small patch of skin removed from Sen. John McCain's right cheek showed no evidence of skin cancer, a spokesman for the Mayo Clinic in Scottsdale said. "No further treatment is necessary," the spokesman, Michael Yardley, said in a statement released through McCain's presidential campaign. The GOP nominee-in-waiting had the skin removed Monday as a precaution during a regular checkup with his dermatologist near Phoenix. The senator, who suffered severe sun damage from his 5 1/2 years in POW camps during the Vietnam War, gets an in-depth skin cancer check every few months because of a medical history of melanoma.

The more you use a tanning bed, the higher your risk of deadly skin cancers, according to research presented at an international cancer conference this week. Researchers from Brigham and Women's Hospital and Harvard University in Boston followed 73,494 nurses who participated in a health study from 1989 to 2009, tracking their tanning-bed habits during high school and college, as well as between the ages of 25 and 35. They also tracked overall average usage during those two periods in relation to basal cell carcinoma, squamous cell carcinoma and melanoma -- three different skin cancers that are each named after the type of cells they affect.
