We learned agriculture and animal husbandry with added chemicals only a few decades ago.
We also learned to use different synthetic chemicals (internally and externally on skin) as a part of modern lifestyle.
Use are now accustomed on use of different types of plastics as a part of our lifestyle.
We are also accustomed on food additives, fast foods and chemical drinks.

Can it be said that present technology is leading us to the painful death of cancer?
