(NaturalNews) A previous USA study reported by Natural News concluded that cadmium toxicity causes premature apoptosis of bone cells (the normal death of a cell to allow new cell generation), which disrupts the normal life/death cellular cycle, causing an imbalance of bone formation and leading to a cascade of signals that bring about bone disease (http://science.naturalnews.com).
Similar conclusions were drawn for lung cell cadmium toxicity issues and other severe cadmium toxicity issues, including kidney damage, until a more recent 2009 UK study. The newly discovered mechanics are different, but the cancerous consequences are the same. In the 2009 UK animal study, researchers discovered that cadmium toxicity in the lungs causes inflammation first and then cell proliferation.
First, the LD50 was determined in order to establish what would be a sublethal dose of cadmium so that mice could be put through a trial of daily, low-dose exposure to cadmium. LD50 is a common term for the dosage that kills 50% of trial subjects. That's also how they test pharmaceuticals. Anyway, the sublethal dose was established at 5 mg/kg body weight.
Instead of an imbalance due to unnatural or premature healthy cell apoptosis, what occurred in their study first was simply severe inflammation and then lung cell proliferation, which is rapid cell division and growth that may lead to cancer.
However, NSAID compounds that reduce the expression of inflammatory cytokines had no inhibitory effect on cellular proliferation, indicating that proliferation was a separate issue and not solely a factor of inflammatory cytokines, despite the sequence's implied causal effect.

What's the bottom line?
Not everyone is involved with zinc smelting or welding that produces cadmium as a byproduct. Nor are many involved with making batteries that contain cadmium. Very few live near such industries, but those who do should be aware of potential air and water cadmium pollution from them.
What many more do that exposes them and others around them to cadmium inhalation is smoke cigarettes. Cigarette smoke contains cadmium. And continual cigarette smoking exposes one to chronic, low, sublethal amounts, which is compounded by the fact that it is inhaled into one's lungs.
Ingesting cadmium with food or water leads to absorbing 5 to 10% of the cadmium content, whereas cadmium via the lungs leads to 90% absorption. So a little cigarette smoke goes a long way for the daily smoker, and those with whom the smoker lives or works get a share of that too. Second hand smoke is not bunk.
Hardly anyone in the medical community mentions another more ubiquitous source of cadmium inhalation - high-altitude aerosol spray geoengineering, commonly called chemtrails. Various water and air traps have collected samples of chemtrails' fallen particulates after a chemtrail event. Most were heavy metals, and they were analyzed at well beyond toxic levels.
Of course, cadmium was one of those heavy metals. Remember, 90% of cadmium content absorption is achieved through inhalation, and those high-altitude heavy metal nanoparticles do drift down into the lower atmosphere from the stratosphere where they're sprayed.
Pooh-pooh chemtrails at your own peril, the way cigarette smokers cavalierly shrug off cigarette dangers at five bucks a pack.
Otherwise, invest your time and energy into low-cost DIY heavy metal detox/chelation remedies that you can research on Natural News, and do them frequently. The estimated half-life of cadmium in a human is 10 to 30 years.
One agent that gets overlooked often is cliniptolite zeolite in powder form. Another overlooked item, food-grade, activated charcoal powder (not capsules) may also be beneficial.
