Is there any study with significant scientific value proving that sunscreen can directly or indirectly cause skin cancer?
I do believe that they protect the skin from the UVA and UVB thus reducing the risk of cancer.
Oxybenzone is being mentioned as a sunscreen chemical with high risk of causing cancer. Retinyl Palmitate is mentioned to be increasing the speed of development of malignant cells. However, after analysis of the ingredients of several sunscreen creams and lotions (Nivea, Garnier Ambre Solaire and Eucerin Sun Protection) I didn't find any of these compounds.
