Down under, we are heading into another summer and so will need to be vigilant about sun safety, given the increased risk of skin cancers that goes with CLL. For those that wonder whether smearing a chemical concoction over the largest organ in your body is wise, the Queensland University of Technology has undertaken a world-first human study to assess the impact of sunscreen at the molecular level. (Queensland is renown for having the highest rates of skin cancer in the world.) In a clinical trial of 57 volunteers that provided skin biopsies, researchers found (SPF30+) sunscreen provides 100 per cent protection against all three forms of skin cancer: BCC (basal cell carcinoma); SCC (squamous cell carcinoma); and malignant melanoma. Further, they found that sunscreen applied to the skin before UV exposure, completely blocked the effects of DNA damage, p53 induction, and cellular proliferation in both melanocytes and keratinocytes.

PS I didn't see anyone out getting a tan when I took this beach photograph. The wind whipped up the foam nicely, with one blob of airborne foam just missing the camera lens.
