do hot dogs cause cancer?

Eat fewer hot dogs: Hot dogs are relatively cheap and taste good. Watch out however for what's in them--read labels carefully to assess what meat is used and how much fat and preservatives are involved in their manufacture. Excessive dietary animal fats have been associated with an increased risk of cancers of the GI tract . Instead, eat a well balanced diet high in monosaturates, whole grains, fruits, vegetables.

Hot Dogs and Cancer: Hot dogs and other processed meats containing nitrites as preservatives are associated with cancer in some studies, since the nitrites can be converted to cancer-causing nitrosamines. Vitamin c is known to decrease the actions of nitrosamines in the body.
Dr. Ed Friedlander

I doubt it: Despite the presence of nitrites as preservatives and heterocyclic hydrocarbons that mutate DNA in cell cultures (as in any flame-cooked food), studies are inconsistent and even the 2005 study in the JAMA (red meat) shows only at best a weak effect. "The Cancer Project" is a group of activist vegetarians citing studies selectively and, in my opinion, misleadingly. It's their billboard.

When can I let my baby play with a pet dog?

Dr. Nanette Nuessle
Specializes in Pediatrics
3-4 days: If your infant and the dog are being supervised, and the dog is up to date on his immunizations, there really is no early age limit. Your infant can be exposed to your dog as soon as your baby comes home from the hospital. If your dog goes outside, this may be an opportunity to enhance your infant's immune system by exposing the baby to allergens in small amounts.

Family history: Risk factors for prostate cancer include a family history of prostate cancer, especially your father. In addition african american males tend to have a higher incidence of prostate cancer as well. A recent study has shown a slight increase in prostate cancer in patients who take vitamin E supplements. Prostate cancer has not been linked to food products.

Besides cell phones, what are other sources of rf energy that cause cancer?

2 doctor answers5 doctors weighed in
Dr. Andrew Turrisi
Radiation Oncology 47 years experience
Proof of cell: Phone link not yet in, microwaves are relatively safe, but radiation is in the electromagnetic spectrum and is a clear cause, and u-v light is part of the spectrum causing skin cancers. All seem to demonstrate direct links to dose and time of exposure. X-rays seem to have no threshold, but very low doses are very unliklely to lead to individual harm, but to a population, a small number will.

How come there are so many new drugs but we cannot find the cure for cancer?

Cancer is not: One disease, or one genetic chnge, but many. Drugs are poisons with side effects, and tumors are smart enought to learn to resist. Single genetic mutations are cured with miracle drugs. Many drugs now hope to keep cancers at bay and allow you to live with the cancer rather than obliterating it. The most fearsome of cancers is glioblastoma (brain tumors) and pancreas cancer. Few baby steps only.
