Enhanced Annuities

Good afternoon all, I have a 69 yr old female client who has had 3 incidents of cancer over last 10 years and is in generally poor health.
Which enhanced annuity provider do you think might offer the best terms for her - comparison sites suggest Just, but maybe there is another provider that offer better terms for cancer sufferers specifically? any ideas gratefully received
Many thanks
