  "term": "tumor DNA sequencing",
  "field": "Oncology and biomedicine",
  "definitions": [
    "A laboratory method used to learn the exact order (sequence) of the chemical building blocks that make up tumor DNA. Errors in the sequence of the building blocks can cause cancer cells to grow and spread. Knowing the DNA sequence of a person’s tumor may help plan treatment that targets the specific error in the tumor.",
    "Sequencing of somatic tissue, such as tumors, refers to looking for variants in DNA that typically occur after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children. These variants can (but do not always) cause cancer or other diseases."
