(Reuters) - Young men who had smoked marijuana recreationally were twice as likely to be diagnosed with testicular cancer than men who have never used marijuana, according to a U.S. study.

Researchers whose findings appeared in the journal Cancer said the link appeared to be specific to a type of tumor known as nonseminoma.

"This is the third study consistently demonstrating a greater than doubling of risk of this particularly undesirable subtype of testicular cancer among young men with marijuana use," said Victoria Cortessis of the University of Southern California, Los Angeles, who led the study.

"I myself feel like we need to take this seriously now," she added, noting that the rates of testicular cancer have been rising inexplicably over the past century.

The research isn't ironclad proof that the marijuana is to blame, and even if it is, the danger isn't overwhelming. According to the American Cancer Society, a man's lifetime risk of getting testicular cancer is about one in 270 - and because effective treatment is available, the risk of dying from the disease is just one in 5,000.

So far, little is known about what causes it. Cortessis said undescended testicles, in which the testes remain in the abdomen beyond the age of a year, are a risk factor. Both pesticide and hormone exposure have also been associated with the tumors.

Cortessis and her colleagues used data from 163 young men who had been diagnosed with testicular cancer and nearly 300 men in a comparison group without the disease. Both groups had been interviewed about their health and drug use between 1987 and 1994.

Among the men with cancer, 81 percent had used marijuana at some point, whereas that was the case for 70 percent of the comparison group.

By contrast, cocaine use was linked to a smaller risk of the tumors. That's important because it signals that men who have been diagnosed with cancer aren't just more honest about their drug use, thereby creating a spurious link between marijuana and cancer, Cortessis said.

It's not entirely clear how marijuana would influence men's cancer risk, but Cortessis said developing testicles may somehow respond to the drug's main active ingredient.

The new study is "interesting," said Carl van Walraven of the University of Ottawa in Canada, who has studied testicular cancer, but said it has a number of limitations.

For instance, it didn't find an increased risk among men with higher marijuana use, and it was relatively small.

But Cortessis highlighted the consistent results from all the studies so far.

"It is hard to imagine a scenario whereby it is due to chance and I can't think of a systematic bias that would cause this. I will feel very confident that this is cause and effect once we have worked out the biology," she said. SOURCE: bit.ly/UEE61v

The incidence of testicular cancer is continuing to increase among US males, despite the plateau of the 1990s. Between 1975 and 2004, the age-adjusted incidence rate for males aged 15-49 years increased from 2.9 (1975) to 5.1 (2004) per 100,000. The trends indicated a percentage change of 71.9% and a statistically significant annual percentage change of 1.6% (95%CI 1.3-2.0; P<0.05). Although the incidence of testicular cancer in Blacks remained strikingly low (0.3-1.4 per 100,000), the highest annual percentage change was observed among this group (2.3%, 95%CI 0.8-3.9; P<0.05 for trends). The rates were intermediate among Asians/Pacific Islanders and American Indian and Alaska Natives (0.7-2.9 per 100,000), with a percentage change of 117.3% and a statistically significant annual percentage change of 1.5% (95%CI 0.3-2.7; P<0.05 for trends). The highest rates were reported among Whites (3.2-6.3 per 100,000), with a percentage change of 90.4% and a statistically significant annual percentage change of 2.0% (95%CI 1.6-2.3; P<0.05). The most common age at diagnosis was 30-34 years, while the lowest rates were reported in those aged 15-19 years. Likewise, incidence rates varied by SEER areas, with predominantly White states representing areas associated with the highest reported rates of testicular cancer.
5.1 (2004) per 100,000 = 0.0051 %

Can some one make a list for what does not cause cancer please...:erm:
Pure water

thats about it :p

anyways its not the weed itself thats causing the cancer its the things you smoke it with like paper unignited gases in lighter and bla bla bla. If it has to be smoked it can cause an increase risk for cancer.

Though these are just risks btw doesnt mean you will get cancer from it. If its not radioactive or high concentrations of hormones dont worry about it, you live once and you cant live forever. So you decide whats sensible or not

EDIT:

elemental oxygen is extremely dangerous anything above 40% can be lethal D:

Yo! That stuff is lethal!

What are some of the dangers associated with DHMO?

Each year, Dihydrogen Monoxide is a known causative component in many thousands of deaths and is a major contributor to millions upon millions of dollars in damage to property and the environment. Some of the known perils of Dihydrogen Monoxide are:

Death due to accidental inhalation of DHMO, even in small quantities.
Prolonged exposure to solid DHMO causes severe tissue damage.
Excessive ingestion produces a number of unpleasant though not typically life-threatening side-effects.
DHMO is a major component of acid rain.
Gaseous DHMO can cause severe burns.
Contributes to soil erosion.
Leads to corrosion and oxidation of many metals.
Contamination of electrical systems often causes short-circuits.
Exposure decreases effectiveness of automobile brakes.
Found in biopsies of pre-cancerous tumors and lesions.
Given to vicious dogs involved in recent deadly attacks.
Often associated with killer cyclones in the U.S. Midwest and elsewhere, and in hurricanes including deadly storms in Florida, New Orleans and other areas of the southeastern U.S.
Thermal variations in DHMO are a suspected contributor to the El Nino weather effect.
What are some uses of Dihydrogen Monoxide?

Despite the known dangers of DHMO, it continues to be used daily by industry, government, and even in private homes across the U.S. and worldwide. Some of the well-known uses of Dihydrogen Monoxide are:

as an industrial solvent and coolant,
in nuclear power plants,
by the U.S. Navy in the propulsion systems of some older vessels,
by elite athletes to improve performance,
in the production of Styrofoam,
in biological and chemical weapons manufacture,
in the development of genetically engineering crops and animals,
as a spray-on fire suppressant and retardant,
in so-called "family planning" or "reproductive health" clinics,
as a major ingredient in many home-brewed bombs,
as a byproduct of hydrocarbon combustion in furnaces and air conditioning compressor operation,
in cult rituals,
by the Church of Scientology on their members and their members' families (although surprisingly, many members recently have contacted DHMo_Org to vehemently deny such use),
by both the KKK and the NAACP during rallies and marches,
by members of Congress who are under investigation for financial corruption and inappropriate IM behavior,
by kids who play Beyblades,
by the clientele at a number of bath houses in New York City and San Francisco,
historically, in Hitler's death camps in Nazi Germany, and in prisons in Turkey, Serbia, Croatia, Libya, Iraq and Iran,
in World War II prison camps in Japan, and in prisons in China, for various forms of torture,
during many recent religious and ethnic wars in the Middle East,
by many terrorist organizations including al Qaeda,
in community swimming pools to maintain chemical balance,
in day care centers, purportedly for sanitary purposes,
by software engineers, including those producing DICOM software and other DICOM software tools,
by popular computer science professors,
by the semi-divine King Bhumibol of Thailand and his many devoted young working girls in Bangkok,
by the British Chiropractic Association and the purveyors of the bogus treatments that the BCA promotes,
by commodities giant Trafigura in their well-publicized and widely-known toxic-waste dumping activities in Ivory Coast,
in animal research laboratories, and
in pesticide production and distribution.
What you may find surprising are some of the products and places where DHMO is used, but which for one reason or another, are not normally made part of public presentations on the dangers to the lives of our family members and friends. Among these startling uses are:
as an additive to food products, including jarred baby food and baby formula, and even in many soups, carbonated beverages and supposedly "all-natural" fruit juices
in cough medicines and other liquid pharmaceuticals,
in spray-on oven cleaners,
in shampoos, shaving creams, deodorants and numerous other bathroom products,
in bathtub bubble products marketed to children,
as a preservative in grocery store fresh produce sections,
in the production of beer by all the major beer distributors,
in the coffee available at major coffee houses in the US and abroad,
in Formula One race cars, although its use is regulated by the Formula One Racing Commission, and
as a target of ongoing NASA planetary and stellar research.
