Has there been a real increase in the amount of brain cancer?

Q. I can think of 4 people I've known who either have it, or have already died of it, plus several famous people seem to have had it as well. Is there an actual statistical uptick in the amount of brain cancer? Part B--some people say that IF there is an uptick, it might be due to cell phone use. While I accept that as a possible explanation, could it also be possible that dental X rays might have caused some brain cancers, too?

A. Well, i am 80 years old, and in my time i have heard every mortal thing given as the cause of cancers, but very very few are ever proved to be right.After the atom bomb tests that was to blame,so was SPUTNIK then luminous watches, the list goes on, and still we have no definitive reason.Lung cancer is put down to smoking,OK but what about the rest,...breast, testicular,liver, bowel and so on. My personal view is we must be ingesting some thing that our body does not like.I do hope its not chocolate cause i love it.

Tell me how cell phones are dangerous to the human body and how they are not?

Q. I need to write a persuasive essay on this topic so help me please.
i am on the cell -phones- are- dangerous side.

A. Actually it has been proven. The long term study I have is on the risk factor for brain cancer. There's other studies showing a decrease in sperm count and also prostate or testicular cancer, can't remember which, in men who carry it in the pants pocket.

Can radiation affect testosterone levels?

Q. I'm doing a project for biology involving the use of cell phones and the radiation that they give off. I've heard that the radiation levels can affect testicular cancer (for men who keep cell phones in their pockets) and breast cancer (for women who keep cell phones in their bras), but can the radiation given off from cells affect testosterone levels in either sex?

A. Your cell phone is glued to your ear: Researchers at the Cleveland Clinic discovered that the more time men spent on their cell phones, the lower their sperm counts. Men who spent four hours a day or more on their cells had the lowest sperm counts and men who didn't use cell phones at all had the highest. A separate Australian laboratory study figured out why: The 1.8 gigahertz frequency used by cell phones increased the amount of free radical damage on sperm, reducing their ability to swim and increasing DNA fragmentation.â
