2. Cancer

3. Tumors

4. Carcinogens
(Substances)
UV Light
viruses

5. Angiogenesis
process through which new blood vessels form from pre-existing vessels

6. Metastasis

7. Proto-Oncogene/Oncogenes
Proto-oncogenes code for proteins that help to regulate cell growth and differentiation
The proto-oncogene can become an oncogene by a relatively small modification of its original function (MUTATION)
oncogene can promote or allow the uncontrolled growth of cancer
MUTATION in proto-oncogene=oncogene (allows cancer)

8. Tumor Suppressor Gene
a gene that reduces the probability that a cell in a multicellular organism will turn into a tumor cell
MUTATION in gene= tumor cell growth
