In toto, there is strong circumstantial evidence from both experimental
and clinical studies to support a role for omega-3 FA in the prevention
of non-melanoma skin cancer (NMSC). In experimental animal studies
there is direct evidence that dietary omega-3 FA inhibits ultraviolet
radiation (UVR) carcinogenic expression, with regard to both increased
tumor latent period and reduced tumor multiplicity. Equivalent levels
of omega-6 FA increase UVR carcinogenic expression. Dietary omega-3 FA
dramatically reduces the plasma and cutaneous pro-inflammatory and
immunosuppressive PGE(2) levels in mice. Dietary omega-6 FA increases
prostaglandin E synthase type 2 (PGE(2)) level. Dietary omega-3 FA
significantly reduces the inflammatory response and sustains, or
enhances, the delayed type hypersensitivity immune response in mice
when compared to an equivalent dietary level of omega-6 FA.
Supplementary omega-3 FA significantly increases the UVR-mediated
erythema threshold in humans. Supplementary omega-3 FA significantly
reduces the level of pro-inflammatory and immunosuppressive PGE(2)
levels in Ultraviolet B-irradiated human skin.
