Summary of cancer

  • Initiation, the first stage, is a mutation in the cell’s DNA structure following exposure to a chemical, radiation, or viral agent. The mutation may also be inherited.
  • Promotion, the second stage in the development of cancer, is characterized by the reversible proliferation of the altered cells.
  • Progression, the final stage, is characterized by increased growth rate of the tumor, increased invasiveness, and spread of the cancer to a distant site (metastasis).
