Hi Newbie. The lymph nodes are swollon because you are likely fighting a virus. Our immunesystems are geared different than the average person. We lack the antibodies to fight candida and a bunch of other stuff because our organisms produce certain protiens that inhibit our clean-up cells from doing their job in this area. The body therefore compensates but increasing other cellular mechanisms which give us allergies, and chronic conditions. Cancer will be detected in routine blood work.
