I was wondering about the chemical sodium laureth sulfate. I have received several forwarded e-mails about this causing cancer by a lawyer looking into the matter. This chemical was said to be in many shampoos to create a nice lather, but it's actually a garage cleaner and is a cheap substance for the manufacturer, and in the past, only 1 in 2000 would get cancer from this, and now it's about 1 in 10. I was just curious if it really causes cancer, or is it just a prank? And if it really does cause cancer, what kind of cancer is it? Thank you. I would appreciate an honest answer.

I have a friend who thinks he may have testicular cancer. I am the only person who knows. He is really embarrassed about it and refuses to tell anyone else. But I think his main problem is that he's afraid of what would happen next if it turns out that he did. I'll often tell him that it's not that embarrassing and he can tell his parents, but since I'm a girl, I just don't understand.

I have tried absolutely everything to make him tell someone, anyone really. But he won't. I am truly scared for him and have no idea what I would do without him. What should I do? Thanks for taking the time to read this, I really appreciate it and could really use the help.

Here's a question I have been debating with a friend for a while, and seeing as how I'm not scheduled to go to the dentist again for a while, I thought you could shed some light on the issue: when brushing one's teeth, should one also brush one's tongue? I would think yes, because what's the point of brushing germs off teeth if the tongue still has them there, and will transfer them to the teeth as soon as you're done brushing. My friend thinks it makes absolutely no difference. So does it matter? We have an ice cream wagered on this one! I hope I'm right!
