Last time I checked my email, I read an email message from my friend who warned us to be careful in choosing our deodorants because there is said to be a chemical or substance found in deodorants that is linked to the cause of cancer. I can't recall the name of the chemical but the email warns us against dry stick deodorants. Oh no! It further says in the email that women should not use a deodorant after they shave because the harmful chemicals could directly enter the body through the open pores.
