Question

essay on "cancer-caused by tobacco"

Answer 1

Here is an essay on ‘Tobacco and Cancer’ which states – How smoking or consuming tobacco can trigger the development of cancer.

Once the importance of environmental factors in triggering the development of cancer had been established, the question arose as to the identity of the agents involved. At the top of the list is tobacco smoke, now known to be responsible for roughly one of every three cancer deaths.

Tobacco smoke is responsible for approximately one-third of all cancer deaths.The first indication of the dangers posed by tobacco smoke came from the emergence of lung cancer as a major disease. Lung cancer was one of the rarest forms of cancer prior to the twentieth century, with only 140 cases reported in the entire world medical literature up until 1898.
