Although I typically don't sear meat, and definitely don't cook it well done, this makes me very, very sad:

Excerpt below, emphasis mine:
The suggestions include reducing cooking times (no smoking), microwaving your meat (???? Yuck!) and avoiding sear. They also SUGGEST using gas over charcoal. I... I can't take it. I have to sit down. I'm... I'm getting dizzy.

When meats are grilled, broiled, or seared, the high cooking temperature breaks down the amino acid creatine (an amino acid found in muscle), forming chemicals called heterocyclic amines (HCAs). The federal government added HCAs to its list of known carcinogens in 2005. Some of the highest concentrations of HCAs are found in grilled meats, according to a 2003 study published in the International Journal of Food Science and Technology. Grilling meat provides the right conditions for HCA formation because more HCAs are produced the longer and hotter the meat cooks.

Excerpt below, emphasis mine:
- Heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs) are chemicals formed when muscle meat, including beef, pork, fish, and poultry, is cooked using high-temperature methods, such as pan frying or grilling directly over an open flame.
- The formation of HCAs and PAHs is influenced by the type of meat, the cooking time, the cooking temperature, and the cooking method.
- Exposure to high levels of HCAs and PAHs can cause cancer in animals; however, whether such exposure causes cancer in humans is unclear.
- Currently, no Federal guidelines address consumption levels of HCAs and PAHs formed in meat.
- HCA and PAH formation can be reduced by avoiding direct exposure of meat to an open flame or a hot metal surface, reducing the cooking time, and using a microwave oven to partially cook meat before exposing it to high temperatures.
- Ongoing studies are investigating the associations between meat intake, meat cooking methods, and cancer risk.
