    Hi @Jack Kruse and all.
    Large debates and discussions going on here in Aussieland on many a facebook and internet sites regarding Hugh Jackman and his latest skin cancer diagnosis.
    What frustrates me is that there are still so many Australians that go on and on about how we 'should' use sunscreen due to our ozone layer and sun affect. But they just don't seem to get not just the fact re the chemical damage of sunscreens but the whole 'doughnut hole' affect that you write about.
    There is just so much more to this...............
    When will so many Australians learn? I reckon when we have Jack Kruse come on down....................

    the diagnostic criteria have changed, whereby quasi malignant lesions are now diagnosed as cancer, and on top of that a very large amount of people get skin cancer from indoor light and UVA exposure through windows without the UVB which signals apoptosis of malignant cells via vitamin d synthesis. So going inside can give you cancer.

    http://www.ncbi.nlm.nih.gov/pubmed/19519827

    This is from Medical Hypothesis:

    "We hypothesize that one factor involves indoor exposures to UVA (321–400nm) passing through windows, which can cause mutations and can break down vitamin D3 formed after outdoor UVB (290–320nm) exposure, and the other factor involves low levels of cutaneous vitamin D3.

    After vitamin D3 forms, melanoma cells can convert it to the hormone, 1,25-dihydroxyvitamin D3, or calcitriol, which causes growth inhibition and apoptotic cell death in vitro and in vivo.

    … We agree that intense, intermittent outdoor UV overexposures and sunburns initiate CMM [cutaneous malignant melanoma]; we now propose that increased UVA exposures and inadequately maintained cutaneous levels of vitamin D3 promotes CMM."

  3. Thanks AJT great looking out
    Sunscreens tend to only block UVB too right?
