Not that I'm aware of. Nor had I heard of the time that the leaves fell off of everything, so who knows the extent of it. I just heard that it was tested in the area.
My grandmother had died of lung cancer, but she also smoked a lot, plus she came from the day before ovens, cooking over open flames, so who knows.
My grandfather later kept getting checked for stomach problems, they said it was gallstones over and over, then after a couple of years of this, they discovered it was cancer but by that point it had spread to his stomach and it was too late.
An uncle, their son, also passed away from cancer between them, but I don't know if he had ever lived in that house as they have been raised in another town.
Puerto Rico has the second highest cancer rate in the United States, right below New Jersey. There's a lot of pollution from factories and lax laws, so who knows what the causes really were.
