I agree that red meat and processed meat can increase your cancer risk from a number of factors, such as the type of meat, its quality, what the animal ate, its exposure to chemicals, how the meat is cooked, and more. So for the WHO to lump all red meat and all processed meat together and saying it's unsafe doesn't help in the confusion they have caused the public.
What isn't mentioned in the recent media articles is that there are a LOT more factors involved in cancer development and progression, or much to the horror of vegetarians and vegans, many plant-based foods may also cause cancer - if plants/vegetables/fruits are exposed to certain toxic chemicals in pesticides and herbicides such as Roundup (or others containing glyphosate) which the WHO announced earlier this year is also "probably" cancer-causing.
As eating meat has many health benefits, you can reduce your cancer risk in many ways, but just one I'm mentioning here is by eating your vegies! Recent research has shown that vegetables have many cancer-preventing and cancer-fighting compounds, and eating vegetables with your meat can nullify the potentially dangerous compounds resulting from cooking meat! This benefit can come from mostly green leafy vegetables and the cruciferous/brassica vegetables (cabbage, broccoli, cauliflower, Brussels sprouts).
So you can go ahead and have your grass-fed steak, but have a salad and some steamed broccoli to go along with it! And I will go one step further and suggest that all ingredients are organic too!
