So, what is a cancer cluster? And how does it affect your health?
A cancer cluster is the repeated occurrence of a particular type of cancer in a specific community or neighborhood. Because of its health hazards, a cancer cluster requires medical intervention and investigation to determine the causes of the outbreaks of cancer.
Cancer occurrence may be due to the pollution of the air, the underground water, the toxic waste dumps, and the power lines, among others.
If repeated outbreaks have occurred in a specific neighborhood or at workplace, then there should be concern from the authorities about the formation of a cancer cluster.
For example, in shipyards, due to the greater exposure to asbestos, shipbuilders are more prone to lung cancer; or in factories where there is greater exposure to vinyl chloride, workers have higher risk of liver cancer. These work environments are grounds for cancer clusters.
Although there have been many cancer cluster investigations, very few of them have produced tangible results, that is, a definitive connection of a cancer outbreak with a certain chemical or toxic material. In addition, given that cancer may take many years to develop in an individual, proving the cause and effect of cancer due to an external factor is extremely difficult, if not impossible.
To illustrate, breast cancer has increased significantly in recent years. This drastic increase may be attributed to several factors. Nowadays, many women tend to bear children later in life because of their career, and this trend may affect their hormone balance. Having children earlier may decrease breast cancer risk, while delaying childbirth may increase the risk. Other factors, such as obesity, diet and lifestyle, also play a critical role in the incidence of breast cancer. Therefore, to pin down the cause of breast cancer to a specific agent is almost impossible. For this reason, common cancers, such as breast cancer, do not fall into a cancer cluster.
Indeed, given that each type of cancer has its unique causes and risk factors, only the frequent causes of the same type of cancer, which does not occur frequently elsewhere, can be counted towards a cluster and compared against background rates.
There are approximately over one million cases of cancer diagnosed each year in the United States. So, to prove or to investigate into the possibility of a cancer cluster, there must be many cases of similar type of cancer outbreak in a specific geographic area. In addition, this type of cancer must be uncommon, or at least apparently less frequent elsewhere. Furthermore, there must be an evident source of environmental pollution as the cancer agent.
That said, it is still difficult to prove the formation of a cancer cluster, simply because of the power of the establishment to stop it, as portrayed in the movie "Erin Brochovich."
The moral of the story is this: Be vigilant of the environment - the place you live in, the place your work at, and the chemicals or toxic substances you may be directly or indirectly exposed to. Prevention is better than cure. Beware of the health hazards, whether it is a cancer cluster or not is irrelevant.

Safety And Health Hazards
Understandably, high doses of toxic chemicals can be lethal. But how safe are low doses of these toxic chemicals? If high does are dangerously deadly, why should you be exposed to even the low doses?
Nearly all the food you consume may contain a trace of heavy metals, pesticides, and toxic chemicals. Some of these contaminants are not added to your food: they are naturally occurring contaminant substances due to the environment. However, most of them are added by food manufacturers to make your food more lasting, more appealing, and more palatable.
Most food manufacturers give their products a face-lift or makeover to make them look fresher or of higher quality. For example, cold cuts, hot dogs, and beef jerky are all dyed red to make them look fresh and tantalizing. Even children's candies, popcorns, and cereals are heavily dyed to make them more fun and enticing to young children.
Studies in rats and animals have shown that certain food dyes are toxic and carcinogenic. Certain food colors were banned, and certain food dyes have been approved by the FDA due to insufficient evidence to prove a cancer risk.
Although artificial food colors may not pose a major health risk, other than susceptibility to allergies, there is no regulatory limit on how much a food manufacturer can use in a food product, that is to say, self-regulatory, which in some cases mean "no regulation."
It is sometimes difficult to avoid food colorings totally, given that so many food items in the supermarket are colored to some degree. However, if you are concerned with your health, maybe you should pay more attention to food labels, and select products that use the natural color agents derived from beets, carrots, and spices, instead of those chemical food dyes.
In addition to food dyes, food toxics can also derive from dietary hormones, which are growth-enhancing hormones found in most meats. Residues of these hormones may affect how children mature sexually.
There has been much controversy over growth-enhancing dietary hormones in animals. Canada and some European countries believe that hormones and their metabolites in beef can be toxic and mutagenic; however, the United States insists that the hormones in beef are safe. There you go!
As a wary consumer, simply eat less beef, or buy only "certified organic" beef. Chicken and pigs are not fed growth-enhancing hormones. Another alternative is to get protein from beans and grains.
Of course, farmers apply millions of pounds of pesticides to the crops you eat. However, the risk from pesticides is relatively low to make food toxicity a major health concern. The best way to avoid pesticide toxicity is to buy organic produce. In addition, peel vegetables, such as carrots and potatoes, although their skins are most nutritious; this is a decision you have to make regarding the trade-off. It should be noted that washing the produce will not do much to get rid of the pesticides, which are already in the peels and the vegetables.
But do these food toxics, even in small does, compromise your food safety? The Food and Drug Administration (FDA) is supposed to be responsible for food safety. Given that it is a complex and difficult job, does the FDA rise to the occasion? A consumer may be at a loss as to what to eat or not to eat. The bottom line: Always eat natural and go organic.
