Just read the summary on the cancer sores and all I can say is that I get
terrible cancer sores in my mouth and inside cheeks whenever I eat citrus
fruits or too many tomatoes.  I was told that it was the acid in the citrus
fruits and tomatoes that causes it.  My father and a brother also have the
same problem.  As soon as we gave up the citrus fruits and cut down on the
tomatoes, the problem went away.
