A bundle of scientific reports indicate more than 200 chemicals, found in the air and in consumer products, cause breast cancer in animal tests.

Researchers report in an American Cancer Society publication that reducing exposure to such compounds could prevent many women from developing the disease.

Family history and genetic make-up are responsible for only a small percentage of breast cancer cases. Environmental and lifestyle factors, such as diet, are most likely involved in the majority of cases, say experts.

An article recently published in the International Journal of Cancer says that airborne exposure to some occupational carcinogens appears to increase the risk of noncardia gastric cancer among men.

Noncardia gastric cancer refers to cancer that is in the middle or lower part of the stomach. Researchers from Sweden recently conducted a clinical study to evaluate potential occupational airborne exposures that may be associated with the risk of developing noncardia gastric cancer. This study included over 256,000 men with 200 different jobs.

Conclusions:

• Workers exposed to cement dust has a 50 percent increased rate of noncardia gastric cancer
• Workers exposed to quartz dust had a 30 percent increased rate of noncardia gastric cancer
• Workers exposed to diesel exhaust has a 40 percent rate of noncardia gastric cancer
• Exposure to asbestos, asphalt fumes, concrete dust, epoxy resins, isocyanates, metal fumes, mineral fibers, organic solvents, or wood dust did not appear to increase the risk of noncardia gastric cancers.

Men exposed to these airborne carcinogens may wish to speak with their physician regarding potential screening measures for noncardia gastric cancer.

The image in the photo of diesel exhaust pouring out of the back of the big yellow school bus makes me want to cough and I am no where near the back of the bus. Imagine the children sitting inside the bus, where much of that bus diesel's own exhaust is entering back inside the cabin from cracks in the exhaust train and through windows and doors. Two environmental groups imagined it -- and based on disturbing studies of the effects on school children from the 40 different chemicals classified as toxic contaminants that make up diesel exhaust -- have filed a lawsuit in California to force Laidlaw Transit Inc., of Naperville, Illinois, to put written warnings on buses about the dangers of cancer-causing pollutants the buses emit. Air pollution from diesel exhaust is a known carcinogen. The State of California knows it. The EPA knows it.

Ideally, the Dervaes would reside on a couple of country acres in order to live the organic, self-sufficient eco-friendly and health conscious lifestyle they live. Instead, finding themselves in the middle of an urban landscape, on a simple city block in Pasadena, California, the five member family has transformed the 1/5 acre and city home into a sustainable urban homestead that provides them with enough organic and cancer prevention food that they have turned the excess crops into a lucrative home business.

The family is vegetarian, and the yard blooms with over 350 varieties of edible and useful plants. The 1/10 acre organic garden now grows over 6,000 pounds of organic produce each year. The money from the cottage-industry produce business helps fund purchases of solar panels, energy efficient appliances, and a biodiesel processor. The family makes their own vegetable oil-based bio-diesel fuel to run the family car. They have chickens and ducks, and compost with worms.

The Dervaes family is generous in the time they spend showing others what they are doing, from allowing local school children come take a tour to giving how-to workshops to keeping a blog. For the last three years, I have followed their daily lifestyle with fascination, reading the daily journal they keep. So much in the way they live is a cancer prevention lifestyle. They protect their health, they protect the health of others, and they protect the health of the planet -- in the way they choose to live. All while living in the middle of a city on a small city lot. I think you will enjoy the visit to the Path to Freedom journal.

What is hanging so toxic in the air? According to the latest data from the U.S. Environmental Protection Agency, benzene from cars and trucks that burn gasoline or diesel fuel. Other toxins causing higher risks for cancer where air pollution is the worst are naphthalene and acetaldehyde -- also from vehicles.

Autoblog, one of our sister blogs, has launched AutoblogGreen, which will feature posts on living an eco-friendly lifestyle in all things auto-related in green car culture. They will be keeping a close ear to the ground and fingers to the keyboard to give readers an up-to-the-minute accounting on the auto industry's efforts to create transportation that is fuel-efficient and cleaner for the environment.

From our perspective here at The Cancer Blog, transportation going green means a giant step towards a cancer prevention environment. From air pollution to alternative fuels, check AutoblogGreen out! It's a very cool, forward-thinking blog.
