Not quite, cancers are caused by any mutation that causes the regulatory proteins to stop being produced. Frameshift mutations are the most common cause. This are often caused by additions or deletions. However other mutations can deactivate the gene like a substitutionin the binding site for mRNA transcription.
Mutations, like deletions can occur all across the genome. Since we have large amounts of non-coding DNA, these mutations usually have no effect.
Yes! By defintion mutation is a change in DNA, but most people consider it more of a modification rather than the occasional just missing bit.
We usually refer to missing DNAs as cancers since damaged and missing genetic data are the leading cause of unregulated cell division
