Cancer: Does This Cause Cancer?

Artificial Sweeteners

There is no proof that artificial sweeteners cause cancer.

Despite all the talk -- and chain emails -- there's no proof that these sugar stand-ins raise your risk of cancer. Saccharine did cause cancer in rats, but their bodies react to it differently than ours, researchers say. There hasn't been a cancer warning label on it since 2000. A study of aspartame in people found no link either.

X-rays

Low doses of X-ray radiation increase the risk of cancer by a small amount.

Your dentist covers you in a lead blanket for a reason. Even low doses of X-rays raise your chances of getting cancer, but only by a small amount. In general, the higher the dose of radiation, the more the risk. But there's no amount of this kind of radiation that's totally safe. That's why the EPA limits how much you can get.

Cell Phones

Minimize your exposure to cell phones which emit some microwave energy.

This gadget, which you keep near all the time, gives off the same type of energy as microwave ovens. So far, it hasn't been linked to cancer, but more research is needed. Just to be safe:

  • Save it for short chats or when there's no landline.
  • Use a hands-free device.

Meat

Eating red and processed meat may increase the risk of cancer.

Whether it's processed or red, you need less of it in your life. Just one hot dog a day could boost your chances of getting colon cancer. Luncheon meats, cold cuts, and hot dogs all have preservatives called nitrites, which cause cancer. Smoking meats or cooking them at a high temperature creates compounds called PAHs. Studies are under way to see how they affect people.

Bottled Water

Opaque plastic may contain bisphenol A (BPA), which increases the risk of cancer.

If your bottle is clear plastic, it may contain bisphenol A (BPA). This chemical is used in food and drink containers (except for baby bottles), dental sealants, and other products. Does it cause cancer? The FDA says no, BPA is safe at current levels found in foods. If you're concerned, avoid canned foods and store chow and drinks in clear plastic. For hot food, use glass or steel instead.

Sex

Human papillomavirus (HPV) is a virus that increases the risk of cervical cancer and other cancers.

It's true. Human papillomavirus (HPV), the most common sexually transmitted infection, can cause cervical and other cancers. Most adults who have sex will get this virus at some point. But they won't all get cancer. Most of the time, HPV goes away by itself. To lower your risk:

  • Get vaccinated if you're a female aged 11-26 or a male aged 11-21.
  • Use condoms during sex.
  • Have sex with only one partner.

Dental Fillings

There's no link between mercury and other materials in fillings and cancer.

Don't call the dentist to have your metal filings removed and replaced. Experts say your current ones are safe. Studies have found no link between fillings with mercury and cancer -- or any other disease.

Coffee

Moderate caffeine consumption decreases the risk of cancer.

If you feel your day doesn't really start until you've had a shot of caffeine, you'll love this. New research shows that drinking moderate amounts of coffee (around four cups daily) lessens the risk of some types of cancer, among them liver, prostate, uterus, and some mouth and throat cancers.

Deodorant and Antiperspirant

The potential link between parabens in deoderant and human cancer is unknown.

There are no large studies that support the claims that deodorants or antiperspirants can cause breast cancer. They have different jobs -- deodorant blocks the smell and antiperspirant stops sweat. Many use chemicals that act like the hormone estrogen, which causes cancer cells to grow. These include benzylparaben, butylparaben, methylparaben, and propylparaben. The effects of these parabens on human cancer risk are unknown.

Fluoride

There is no strong link between fluoride and cancer risk.

This compound is found in water and other drinks and in food, toothpastes, and mouth rinses. Though many studies have looked for links between it and cancer, most researchers says there's no strong tie. If you're worried about it, you can ask the Environmental Protection Agency how much is in your drinking water. If it's high, switch to bottled spring water, which usually has the least.

Household Products

VOCs may increase the risk of cancer.

Many pesticides, paints, varnishes, and waxes give off gases known as volatile organic compounds (VOCs). So do some cleaning, cosmetic, automotive, and hobby products. These gases have been linked to cancer in humans and animals. To cut your risk choose products labeled low-VOC and biodegradable when possible. Avoid items labeled as:

  • Danger/Poison
  • Corrosive
  • Severely Irritating
  • Highly Flammable
  • Highly Combustible
  • Strong Sensitizer

Power Lines

Keep a safe distance from power lines and electrical devices to minimize the risk of exposure to extremely low frequency radiation.

Anything that makes, sends, or uses electricity gives off extremely low frequency (ELF) radiation. There's no proof that it causes cancer. Still, the National Institute of Environmental Health Sciences says there's cause for "limited concern." To be safe, stay at least an arm's length away from electrical devices. If you live close to a power line and you're worried, get a gizmo called a gaussmeter. You can use it to measure the ELF fields near you.

Pollution

Air pollution increases the risk of lung cancer.

Air pollution causes over 220,000 lung cancer deaths worldwide a year (most of them in Asia). There's also a link between dirty air and a higher risk of bladder cancer. But the odds for any one person are low. To cut your chances, listen to local smog alerts. Try to stay inside on days when the air quality is poor.
