Titanium dioxide does not cause cancer, and there is no data even implying it does. The “sun block” cancer thing you are probably mis-remembering is Oxybenzone and Para-amino-benzoic acid (PABA) which used to be a common sunblock ingredients which have been implicated in skin cancers. There is, of course, the issue that all sunblocks, by blocking UV, cause a decrease in vitamin D production since your body needs UV to make vitamin D. Vitamin D deficiencies are implicated with heightened cancer risk.

I did read it. As far as I can see, they mention the sunblock, but not the cancer… or they are hiding the word cancer behind scientific gobbledygook.

I thought titanium dioxide was the stuff causing cancer in sunblock?
