The helpline here is open until 5pm tonight 0808 800 6000. Calls are free. Open weekdays 9-5 and Saturdays 10-2.
I remember being aware of this too. Maybe we are just looking at our breast with a bit more interest?
However I suggest you phone your BCN to ask or perhaps contact one of the advisers on this site? Always best to ask if you have any worries at all.
Good luck with everything.
