I presume you're not a woman, because there's cervical screening for women aged 25-64 every five years. Also depends on what you mean by "mid life", but there's breast screening offered to women aged 50-70 and bowel cancer screening offered to people from 50 to 74 every two years.

There are real trade-offs with screening, and screening too much has harms as well as too little, although I'm not qualified to make a judgement on where that line sits relative to where it is in the UK.
