Cancer of unknown primary (CUP) accounts for 3% of all new cases of cancer in the UK (2014). It accounts for 2% of the male total and 3% of the female total.[1-4]
In 2014, there were 8,930 new cases of CUP in the UK: 4,319 (48%) in males and 4,611 (52%) in females, giving a male:female ratio of around 9:10.[1-4] The
Differences in registration practice may have a bearing on comparisons between countries in the UK. The European

For cancer of unknown primary, like most cancer types, differences between countries largely reflect risk factor prevalence in years past.
