Have Reserachers Found The Trigger For Melanoma Growth?

According to a new study published in the journal Science Translational Medicine, the growth of the deadly skin cancer melanoma may be triggered by the immune system turning on itself! Researchers found that the tumor cells somehow use a component of the immune system itself (called interferon gamma) to turn on a specific molecule in melanoma tumors called B7-H1. B7-H1 is an immune-inhibiting molecule that is able to suppress the body's immune surveillance system and potentially allow for tumor growth.

Can A Wart Cause Skin Cancer?

Human papillomavirus, or HPV, is well known to cause warts in people. A new study found that some types of HPV, may increase the risk of nonmelanoma skin cancers. A review of blood sample records in Norway and Sweden shows that people infected with a certain group of HPVs that make their home in skin cells were 30 percent more likely to develop squamous cell carcinoma, a type of skin cancer, over a 30-year period than those not infected with this group of viruses.

Indoor Tanning Worse Than Sunburns For Melanoma

According to a study presented at the American Academy of Dermatology Annual Meeting, indoor tanning might be a more reliable predictor of invasive cutaneous melanoma than outdoor sunburns. The new findings are based on the Minnesota Skin Health Study. Researchers examined 1167 cases of melanoma diagnosed from 2004 to 2007 and 1101 control subjects. Four UV risk factors significantly associated with melanoma were identified including: outdoor lifetime sunburns, indoor tanning, frequency of indoor tanning, and burns from indoor tanning. In comparing these, outdoor lifetime sunburns became much less significant than indoor tanning frequency.

Sun Protection Up, But Sunburns Not Down

A presentation at the annual meeting of the American Society of Preventive Oncology revealed that sun protective measures became more common between 2000 and 2010. However, a corresponding decrease in sunburns was not observed, according to an analysis of national data. Overall among women, staying in the shade, using sunscreen, and wearing clothing to the ankles increased significantly over time by 5%, 6%, and 5%, respectively, between 2000 and 2010. Similarly, among men, staying in the shade, sunscreen use, and wearing clothing to the ankles increased by 7%, 2%, and 5%, respectively. However, the overall prevalence of sunburn did not change significantly over those years. In 2010, 51% of women and 49% of men reported having at least one sunburn in the past year. Researchers believe that by continuing to create environments that support protective behaviors and by changing social norms regarding tanning and tanned skin will ultimately have an impact on the rates skin cancer development.

Women Who Used Tanning Beds May Have Higher Risk Of Skin Cancer

Manicure Maven: What You Need to Know About Gel Nail Polish

A manicure with gel nail polish has the reputation of lasts two weeks or more! For many, this is the long lasting solution also seems better than acrylic nails which often permanently damages nails. But there are a few things to keep in mind before trying this new technique:
  1. Some gel nail polishes contain a chemical called methyl acrylate which can cause an allergic skin reaction, called contact dermatitis. Wherever the chemical comes into contact with the skin, a rash may develop. The rash from methyl acrylate is usually red, itchy, bumpy and uncomfortable. It may last a week or longer. 
  2. The chemical, butylated hydroxyanisol (BHA), which is considered a cancer-causing agent, is found in some (not all) gel nail polishes. Although it is not known exactly how much exposure you need for cancer to develop, it's important to be aware of this connection.
  3. Gel nail polish is set or cured with ultraviolet light. The ultraviolet light is essentially an intense exposure to sunlight. If you are exposed to ultraviolet light for four to eight minutes every two weeks when you have a gel manicure, that can add up to significant exposure and potential lead to the development of skin cancers on the hands and fingers.
  4. To remove gel polish, your nails are soaked in or wrapped in acetone. Acetone is a very drying chemical and will cause your nail to become brittle and peel after repeated use.
  5. The surface of your nail is usually roughed with an emery board before gel polish is applied. This will weaken your nail and lead to breakage and the possibility of infection. 
If you are already sold on gel nail polish, speak to your dermatologist about ways to prevent and combat these potential side effects.

Does Ethnic Background Increase Your Risk Of Scarring After Surgery?

African Americans have a sevenfold increased risk for developing keloid scarring following surgery in the head and neck area compared with Caucasians.

Chemical vs. Physical Sunscreens

We now know the skin's own photoprotection mechanisms are usually not sufficient to protect against ultraviolet radiation for the sun. This UV radiation can result in damage like sunburn, changes in DNA, cell death or cell abnormalities.

Sunscreen therefore is of critical importance. There are 2 basic types of sunscreen: chemical and physical lotions.

Chemical screens are capable of absorbing UV rays and quenching the radiation so it cannot damage the skin.

Physical sunscreens, on the other hand, reflect reflect the UV rays, similar to a mirror.

Whether you choose a chemical or physical sunscreen, make sure the preparation protects against both UV-A and UV-B rays, to ensure you get the maximum sun protection.
