I must be the exception then. I live in the once beautiful gulf coast working construction, and I spend about 8-11 hours outside every day(depening on wether or not i go fishing before or after work). Weeeeell I dont use sunscreen, everynow and then just to shutup and nagging women, but last month or so I had a nice lump removed from the underside of my forearm. Turns out that it was skin cancer. yay.

I don't even need to watch the video to know that they are wrong. ANY form of radiation has the potential to cause cancer, notice that I said potential.
Targeting cancer Another interesting property of liposomes are their natural ability to target cancer. The endothelial wall of all healthy human blood vessels are encapsulated by endothelial cells that are bound together by tight junctions. These tight junctions stop any large particle in the blood from leaking out of the vessel. Tumour vessels do not contain the same level of seal between cells and are diagnostically leaky. This ability is known as the Enhanced Permeability and Retention effect. Liposomes of certain sizes, typically less than 400 nm, can rapidly enter tumour sites from the blood, but are kept in the bloodstream by the endothelial wall in healthy tissue vasculature. Anti-cancer drugs such as Doxorubicin (Doxil), Camptothecin and Daunorubicin (Daunoxome) are currently being marketed in liposome delivery systems.  Manufacturing
