The Genetics of Cancer - NCI - National Cancer Institute
WEBAug 8, 2024 — Multiple kinds of genetic changes can lead to cancer. One genetic change, called a DNA mutation or genetic variant, is a change in the DNA code, like a typo in the sequence of DNA letters. Some variants affect just one DNA letter, called a nucleotide. A nucleotide may be missing, or it may be replaced by another nucleotide.

WEBDNA changes that create oncogenes or that turn off tumor suppressor genes or DNA repair genes might lead to cancer, although typically it takes several gene changes before a cell becomes a cancer cell.
