greys and cancer

["Beth Gunn" <happyhoofprints@hotmail.com>]

CMNewell,

Could you express your opinion here?  If greys have black skin, as they all do, why are they more suseptible?  Does the white hair act as a mirror for the UVs?  If it is not sun related, why do greys exibit this more "melanomas"?

Also, another posted idea that we are not "seeing" the whole picture.  There may be other cancers inside horses body, non-greys, that we are not aware of?

Thanks for the input.
