Better Health: Extra pounds can lead to diabetes. By dropping 5 to 10 percent of your weight, you’ll lower your risk by nearly 60 percent.

Better Brain: Fat may make you forgetful. Shed 10 pounds and, chances are, you’ll stay smarter and more focused.

Better Fitness: For every pound of fat you lose, you move up to 4 seconds faster. Plus, your body won’t have to work as hard to stay active. In addition, your risk for injury will diminish, too, since every pound of body weight translates to about 4 pounds of force on your ankles, knees and hips (10 extra pounds means 40 pounds of pressure on your joints).

Better Mood: You can feel more confident and upbeat by shedding pounds. It’s enough of a change to improve your body image, boost your energy level and support your mental health.

Better Fat Cells: By losing weight, you actually make the fat cells smaller. Translation: smaller waist, slimmer thighs and a lower risk of heart disease.

Better Paycheck: Women with excess pounds make nearly $10,000 less per year than their average-weight coworkers – possibly because they they tend to be less assertive.

Better Sex: Two things that increase sex drive are feeling comfortable with your body and confidence. Losing weight can help increase both of these things.

Marijuana Increases Likelihood Of Testicular Cancer

Smoking may increase a man’s risk for testicular cancer.

A new study found that men who had smoked marijuana were twice as likely to get an aggressive form of the disease. But why?

Testicular cancer is the most common cancer diagnosed in men under age 45. It’s also on the rise, says Scott Eggener, MD, a cancer surgeon at the University of Chicago who has studied the trend.

“No one really knows why,” he says. “Everyone suspects an environmental exposure, but it’s difficult if not impossible to prove.”

A study released earlier this year showed marijuana use is also up, with 1 in 10 teens now smoking pot at least 20 times a month.

Not the First Time

The new study, published in the journal Cancer, is the third in recent years to link marijuana use to the development of testicular cancer.

It compared 163 men with testicular cancer to 292 healthy men who were about the same age and race. All the men in the study were between age 18 and 36 when they were diagnosed.

Men who said they had ever smoked marijuana had more than twice the risk of aggressive testicular tumors, compared to men who did not smoke marijuana.

That was true even after researchers accounted for other things known to affect a man’s risk, like having an undescended testicle.

Oddly enough, men who reported using cocaine had about half the risk of nonusers.

That doesn’t mean cocaine benefits the testes, though.

In animal studies, cocaine has “really devastating effects on the testicles,” says researcher Victoria Cortessis, MSPH, PhD, assistant professor of preventive medicine at the Keck School of Medicine of USC in Los Angeles. “They get smaller and smaller.”

“I don’t think cocaine is protecting the cells from cancer. I think it’s more likely that it’s killing the cells and therefore they aren’t getting cancer,” Cortessis says.

Put It in Perspective

A doubled risk of cancer may sound pretty scary, but researchers caution that men who have smoked pot shouldn’t panic.

That’s because the odds that a man will get testicular cancer are pretty slim to start with. About 1 in 400 white men are diagnosed by the time they are 35, according to the National Cancer Institute. So even if you double that risk to 1 in 200, any one man’s chances are still pretty low.

The study also doesn’t prove that marijuana causes cancer.

In fact, the relationship the researchers found wasn’t easy to explain. Men with lighter habits or who had given up pot smoking had a higher risk of testicular cancer than those who were current smokers or who reported heavier use.

Researchers don’t think that means smoking more pot is actually safer.

Other studies, which were larger, found that cancer risk increased with the size of a man’s pot smoking habit. The new study may simply be too small to show the same relationship.

Doctors aren’t sure why marijuana may increase the risk for certain kinds of testicular cancer. The active ingredient in the drug, THC, is known to disrupt hormone signals in the body. That may put cells in the testes on a path to cancer. More research is needed before researchers can say for sure.

The overall story is that there’s an increased risk in marijuana users. It’s particular to the kinds of testicular tumors that are the most aggressive and therefore the most likely to put a man’s life at risk. What’s more, the finding is pretty consistent amongst these three studies, which is something we should be paying attention to.
