Which of the following is NOT evidence that smoking causes lung cancer?

#Section 3: Genetics, Cellular and Molecular Biology

  1. Epidemiological rates of lung cancer dramatically increased after more people started to smoke.

  2. Exposure of lung cells to the active carcinogen found in cigarettes causes mutations in p53.

  3. Mutations in p53 are found in the same codons in patients with lung cancer who smoke as in cultured cells treated with benzo(a)pyrene.

  4. Epidemiological rates of lung cancer in women increased years after the rates in men increased.
