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

Metastasis

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)

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
