The notion that charred food causes cancer has been around for a long time. We are also told that soaking meat in a marinade before grilling it reduces the risks from eating it.
Personally, I have never put much weight in the study. I think about the saccharin cancer warnings from a few years ago too. However, between the time that saccharin was discovered in 1879 to today not a single case of cancer in a human has been traced to saccharin. That fact alone makes me think that saccharin is probably the safest of all artificial sweeteners. What other artificial sweetener has a 122 year track record?
One other thing to keep in mind is, the saccharin "study" results were published in 1977. That just so happened to be when NutraSweet (aspartame) was trying to get the final FDA approval to begin marketing its artificial sweetener.
Was the study more about selling NutraSweet than real Science? You can decide that for yourself, but I am suspicious. Humans have been eating meat cooked over an open fire for thousands of years and yet I know of no cancer cases directly traced to food because it was grilled or barbecued over a wood fire. That's a pretty good track record too, I think.
Now, who would make up things and/or stretch the truth in an attempt to convince people to stop eating animal flesh? What kind of influence do they have on these kinds of "studies?" I don't know but I am suspicious of that in this case too.
The two primary substances at question produced by charring meat are: Heterocyclic Amines (HCA) and Polycyclic Aromatic Hydrocarbons (PAH).
PAH is on the SUSPECTED carcinogen list, not the known carcenogen list.
There are a lot of people out there who will do any study you want if you pay them enough.

There are some substances higher on the priority list than grilled meats. In fact, PAH's are not known to cause cancer according to the International Agency for Research on Cancer.
http://www.cancer.org/Cancer/CancerC...an-carcinogens
And, you have this - An important proviso to be kept in mind is that cancers in laboratory rats and mice are induced by doses (per unit of body weight) several orders of magnitude higher than what are usually ingested in normal meals by humans. (Typically, the amounts of HCAs are over a million times higher, based on calculations from data furnished in Augustsson [1999].) In fact, by itself, the ingested daily amount of heterocyclic amines is very probably too small to explain the development of human cancers, and the same is true for numerous other carcinogens. Thus, the simultaneous presence of heterocyclic amines with other genotoxic [i.e., inducing DNA damage] carcinogens and with tumor-promoting agents or tumor-promoting conditions makes it very difficult to make a numerical calculation for risk estimation.

The ingredients in Kingsford charcoal and their purpose:
Wood Char - heat
Mineral Char - also for heat
Mineral Carbon - also for heat
Limestone - for the light-ash color
Starch - to bind the other ingredients
Borax - for easy release from molds
Sodium nitrate - for quicker ignition
Sawdust - for quicker ignition
Now, I have no problem with any of those ingredients except the mineral char and carbon which is coal. The problem with coal is the nasty gases it produces.
There was a lawsuit brought against Clorox Co. (Kingsford is a subsidiary of the Clorox Co.) back in 2008 by the wife of a chef named James Beets who was the master chef for 10 years at a Weber Grill Restaurant where they cooked inside using Kingsford charcoal. He was diagnosed with blood cancer and his doctors traced it back to the benzene gas produced by the Kingsford charcoal used in the restaurant's grills. The lawsuit basically said the company failed to warn consumers that using the benzene-containing briquettes indoors could lead to the development of multiple myeloma.
What I find most interesting is that Kingsford introduced their reformulated charcoal in 2009. Did the lawsuit actually prompt the reformulation? That's a question I would like to have an answer to.
Now, will occasionally using Kingsford outdoors result in inhaling enough benzene to kill a person? I don't know of any cases where that has been proven or even suspected. So, I don't have a problem with using it. Now, if I were using it indoors in a kitchen filled with grills even with ventilation, I might be concerned.
Nitrates are fairly stable nitrogen compounds that can be degraded into nitrites. Nitrites are unstable and can combine readily with other compounds in the digestive tract to form carcinogenic nitrosamines. Please google nitrates and vegetables. You don't need to eat BBQ or cured meats to get a good dose of nitrates. On top of all that, burnt toast contains PAHs too.
Anyway, I'm not a doctor, so do your own research and work through it with your doctor.
