I've never worked out why 'cervical cancer' seems to be pronounced 'cervical' ('vic' as in 'victor') when related to the entrance to the womb, but 'cerv-eye-cal' when referring to the vertebrae at the top of the spine.
I think you'll find that most medics in the UK pronounce both the same way: cerv-eye-cal. it's just TV news journalists who don't!
