Of course, I have been thinking a lot about possible reasons for this tumor. Are there really people who can trace back their tumor to the alcohol of Listerine? ( I never used it since March, only a "softer" mouthwash without alcohol). But even more dangerous seems to me the other mentioned chemical. Even more since the package itself contains a warning "do not apply more often than 2 times a day, and not longer than 2 weeks". But this is what I did! So I really should apply for this year`s "Darwin Award" :-(( (readers who should not know the Darwin Award: ask Wikipedia) . But it is so hard to believe: Can a cancer be ignited so rapidly??

Of course I will also fill up a signature. But first I have to understand all those abbreviations, and various data will be available only later.
