After many large-scale sequencing projects of cancer genomes, we now understand that many genetic alterations in specific cancer genes are responsible for the development and progression of the disease. These alterations may occur at the level of the patient’s germline, predisposing to inherited forms of cancer that may develop in many tissues throughout the body. Genetic alterations may also be somatic, or newly acquired changes within the genes of an individual cell or group of cells over time and due to environmental stresses. Somatic alterations may come in many forms, including single-base substitutions; insertions or deletions of DNA fragments; rearrangements and rejoining of DNA from alternative locations in the genome; and copy number increases and reductions. Should these alterations effect key cancer genes, malignancy may develop.
