You know air pollution is dangerous, but what about the air INSIDE your home?

You might want to get your homes checked to see if you’re harboring an invisible killer in the air. According to Dr. Aaron Goodarzi of the University of Calgary, houses may have well over the safe exposure limit of radon gas.

In an article in the Daily Mail, Dr. Goodarzi writes that at least one in 15 homes in the U.S. contain the invisible gas.

Radon, a radioactive, invisible, and colorless gas, is a major cause of lung cancer after cigarette smoke. In Canada, at least 4,000 new cases of lung cancer are attributed to radon exposure, while experts estimate 15,000 to 22,000 lung cancer deaths in the U.S. are linked to the gas.

He and his research team have been testing well over 2,300 homes in Canada for radon for years. According to the results of the testing, at least one in eight homes that were tested contained radon levels that are higher than acceptable levels. Interestingly enough, newer houses have the largest problem with radon levels.

However, the problem lies, according to Dr. Goodarzi, with people’s lack of awareness on the effects of radon gas.

Radon is a radioactive gas that’s invisible and contains no odor. While it naturally occurs from the breakdown of radium in the soil, the gas can seep into a building through cracks in the foundation as well as other openings.

It can be mostly found in the basement or cellars of homes, schools, and offices. There is no distinction with radon exposure: It can seep in any building, both old and new, in about all places where there is housing structure.

The correlation between radon gas and lung cancer was made in the 1970s after abnormally high cancer rates were detected in uranium miners in Elliot Lake in Ontario, Canada.

Currently, studies have already established that long-term exposure to radon gas can cause irreparable harm to the DNA and lead to gene mutations that ultimately will lead to cancer. Next to smoking, radon exposure is the leading cause of cancer in non-smokers. (Related: Radon in Homes is the Second Leading Cause of Lung Cancer.)

Dr. Goodarzi writes that radon exposure is now a major public health concern in Canada. In his location in Alberta alone, he estimates that many patients in Alberta who have never smoked a day in their life, are faced with a high risk for lung cancer.

Still, radon-induced lung cancer can be avoided completely with testing and proper management. Health care costs will be saved by avoiding radon cancer, not to mention a decrease in human suffering.

However, a person who smokes and also lives in a home with radon gas puts him at a much greater hazard, with a one in four chance of developing lung cancer later on. Meanwhile, the percentage of smokers who may have avoided cancer if they were not also exposed to radon gas remains uncertain.

With the advancement of scientific studies regarding the dangers of radon gas, Dr. Goodarzi opines that this will translate to additional legislation to regulate the gas, especially since children have the greatest risk of radon exposure throughout their lives.

As the harmful effects of radon are now gaining ground, the team hopes that this will make radon testing for homes a normal requirement, especially in cases wherein the home was just purchased after a major home repair.

Scientists find early warning signs of several cancers in smokers’ cheeks .


By studying the genetic changes undergone by women who smoke, scientists in the UK have figured out how to detect several types of cancer around the body with almost perfect sensitivity, just by analysing a person’s cheek cells.

The team wanted to investigate how epigenetic changes – changes to a person’s DNA that switch genes on and off, caused by environmental factors such as exposure to cigarette smoke – can be identified early on in epithelial cancers, which encompass 80 to 90 percent of all known cancer types. They say that easily accessible cheek cells could make detecting the early warning signs of well-hidden cancers like ovary, breast and endometrial much simpler in the future.
“Our work shows that smoking has a major impact on the epigenome of normal cells that are directly exposed to the carcinogen,” lead researcher Andrew Teschendorff, from the University College London Cancer Institute, said in a press release. “Of particular significance is that these epigenetic changes are also seen in both smoking-related and non-smoking related cancers, pointing towards a universal cancer program. This research gets us closer to understanding the very first steps in carcinogenesis and in future may provide us with much-needed tests for risk prediction and early detection.”

Teschendorff and his team looked at the epigenetic changes that were occurring in cheek – or buccal – samples taken from 790 women all born in 1946. They found that those who smoked were more likely to display alterations in their epigenomes that were associated with several types of cancers, even those that are not usually linked to smoking. Through their analysis, they were able to come up with an epigenetic ‘signature’ for smoking.

“By looking for this signature, the researchers found they could differentiate between normal and cancerous tissue with near absolute certainty, including cancers in other parts of the body,” Esha Dey reports at Live Science. “The signature could also be used to predict if a pre-cancerous lesion would progress to a full-blown invasive cancer, the researchers said.”

Publishing in the journal JAMA Oncology, the team says that compared to blood samples taken from the female volunteers, the cheek cell samples showed a 40-fold increase in abnormal genetic activities, which makes them a better and more reliable indicator of these early warning signs. They report in the press release that their cheek cell test is able to discriminate between normal and cancerous tissue with almost 100 percent sensitivity and 100 percent specificity, regardless of the organ in which the cancer arose.

“These are significant results for our core interest, which is decoding women’s cancers. We are a big step closer now to unravelling how environmental factors cause cancer,” said Teschendorff. “These results pave the way for other studies in which easily accessible cells can be used as proxies to highlight epigenetic changes that may indicate a risk of developing cancer at a site where cells are inaccessible. This is incredibly exciting for women’s cancers such as ovary, breast and endometrial cancer where predicting the cancer risk is a big challenge.”

The good news for ex-smokers is that the team’s results showed that smoking-related damage experienced by the women in their analyses had been reversed in those who had quit smoking 10 years before the samples were collected, which means it’s never too late to lower your cancer risk if you’re thinking about quitting.

For All Smokers: How to Make a Miracle Elixir to Clean Your Lungs .


If you’ve been smoking for more than five years, you’ve so far certainly had bronchitis, which is characterized by specific coughing.

Normally it would be best to quit them forever, but if you can’t do that, we suggest to you to insert this food in your daily diet along with a recipe for a potion that’ll also help.

Garlic and Onion

You already know a lot of benefits of garlic and onions. They have anticancer effects and excellent prevention of many malignancies. The onion is particularly effective in preventing various respiratory infections.

Ginger

This ancient east spice has been long known for its miraculous curative action. Ginger is also important for the disposal of the layers of secretions in the lungs from smoking.

Turmeric

This stunning yellow spice is rich in vitamins and minerals and contains healing omega 3 fatty acids. Turmeric actsantiviral, antibacterial and anticancer, so it is very desirable to include in the daily diet.

Recipe for a potion that cleans the lungs from smoking:

Ingredients:

  • 14 oz /400 g onions
  • 34 oz /1 liter of water
  • 14 oz /400 g of brown sugar
  • 2 tablespoons turmeric
  • Cleaned small root ginger

Preparation:

Put a bowl on heat. Pour water along with sugar and leave them to boil. Add the cleaned onion, chopped in quarters, and the grated ginger root (about the size of your thumb). Place the turmeric and when it starts boiling, reduce the heat. Simmer until the amount is not reduced twice, strain, put in a glass jar, and when the mixture is completely cool, place it in the refrigerator. Take two tablespoons in the morning (on an empty stomach) and in the evening, two hours after a meal.

Warning: Before you begin the consumption of any medication, consult your doctor or pharmacist.
