Dr. Allen's Tips on How to Find the Best Sunscreen!

Tip 1: UVA and UVB protection 

Tip 2: Zinc Oxide or Titanium Dioxide

Tip 3: SPF

  • Flip the bottle to the back and under Drug Facts it lists the Active Ingredients. The sunscreen should have either Zinc Oxide or Titanium Dioxide or both! These ingredients are the only ingredients that can reflect the sun’s UVA and UVB rays.
  • On the front of the sunscreen bottle look for the words UVA/UVB protection. UVA/UVB rays are the sun’s rays that, if not covered with sunscreen, can penetrate the skin and lead to skin cancer.
  • Although not as important as the first two, the sunscreen should have at least 40 SPF. SPF, or sun protection factor, means the amount of time you can spend in the sun until you get sunburned. So make sure to reapply often!

ABC's of Melanoma

The ABC's of Melanoma is a great way to check yourself for skin cancer! Any ONE of these characteristics is cause for you to schedule an appointment with your doctor.

  • Asymmetry- If there is not a center line, where each side is a mirror image.

  • Borders- Does your 'mole' have crazy edges?

  • Color- Anything with multiple colors (dark, light, etc)

  • Diameter- Is the length the same as last year?

  • Evolution- Moles shouldn't change over time!

Skin Cancer Facts - Did You Know?

  • Skin cancer is the most common of all cancers. About 3.5 million cases of basal and squamous cell skin cancers are diagnosed in this country each year. Melanoma, a more dangerous type of skin cancer, will account for more than 73,000 cases of skin cancer in 2015.5
  • If you added the number of the big four cancers (breast, colon, prostate, and lung) it still doesn’t equal half the number of cases of skin cancer.
  • Current estimates are that one in five Americans will develop skin cancer in their lifetime.1,2
  • Melanoma is the most common form of cancer for young adults 25-29 years old and the second most common form of cancer for adolescents and young adults 15-29 years old.7
  • While melanoma in children is extremely rare, from 1973 to 2009, the rate of melanoma increased by about 2 percent per year among Caucasian children from newborn to age 19 in the United States.3
  • Basal and squamous cancers start in the basal and squamous cells, found in the outer layer of the skin, which is where they get their name. Most basal and squamous cell cancers develop on sun-exposed areas of the skin, like the face, ears, neck, lips, and the backs of the hands. Basal cell cancers tend to grow slowly and rarely spread to other parts of the body. Squamous cell cancers are more likely to grow into deeper layers of skin and to spread, although this is still not common. Both basal cell and squamous cell skin cancers can be cured if found and treated early – when they are small and have not spread. But either type can cause problems if it is left untreated.
  • Squamous cell carcinomas: A persistent, scaly red patch with irregular borders that sometimes crusts or bleeds.11
  • Melanoma is a cancer that begins in the melanocytes – the cells that make the brown skin pigment known as melanin, which gives the skin its color. Melanin helps protect the deeper layers of the skin from the harmful effects of the sun. Melanoma can start on nearly any part of the skin, even in places that are not normally exposed to the sun, such as the genital or anal areas. Though melanoma most often affects the skin (including under the nails), it can also start in other parts of the body, such as in the eyes or mouth. Melanoma is almost always curable when it’s found in its very early stages. Although melanoma accounts for only a small percentage of skin cancers, it’s much more likely to grow and spread to other parts of the body, where it can be hard to treat. Because of this, melanoma causes most skin cancer deaths, accounting for nearly 10,000 of the more than 13,000 skin cancer deaths each year.5

Skin Cancer Facts - Risk Factors

  • Exposure to UV light is the most preventable risk factor for all skin cancers.

  • Seek shade, wear protective clothing and use a sunscreen with a Sun Protection Factor (SPF) of 30 or higher.
    - Because severe sunburns during childhood may increase one’s risk of melanoma, children should be especially protected from the sun.5

  • People should not use tanning beds or sunlamps, which are sources of artificial UV radiation that may cause skin cancer.5

  • Skin cancer warning signs include changes in size, shape or color of a mole or other skin lesion, the appearance of a new growth on the skin, or a sore that doesn’t heal. If you notice any spots on your skin that are different from the others, or anything changing, itching or bleeding, seek medical attention.

  • Perform skin self-exams to check for signs of skin cancer and get a skin exam from a doctor. A dermatologist can make individual recommendations as to how often a person needs these exams based on risk factors, including skin type, history of sun exposure and family history.

  • Individuals with a history of melanoma should have a full-body exam by a board-certified dermatologist at least annually and perform regular self-exams to check for new and changing moles.10
