Key Statistics for Cancers of Unknown Primary
How common are cancers of unknown primary?
The exact number of cancers of unknown primary (CUP) diagnosed each year is unknown, because some cancers start out being diagnosed as unknown primary, but the primary site is found later. Still, the P站视频 estimates that about 34,950 cases of cancer of unknown primary will be diagnosed in 2024 in the United States. This number represents about 2% of all cancers. As more sophisticated lab tests become available to determine where a cancer started, the number of cancers of unknown primary may go down.
