sporadic cancer
(spuh-RA-dik KAN-ser)
Cancer that occurs in people who do not have an inherited genetic variant that would increase their risk for that cancer. Sporadic cancer is sometimes used to differentiate cancers that occur in these people from cancers that occur in people who are known or likely to carry a high-risk variant that increases their risk for cancer. Sporadic cancer is also sometimes used to describe cancer that occurs in people who do not have a family history of that cancer or other associated cancers.
