Hello and thank you for posting.

I am sorry to hear about the two friends who have had bowel cancer. When we lose people we care for it can make us more aware of our health.

Unfortunately, we are unable to say why your nipples may be inverting. We would always suggest that if people notice any changes that concern them to have them reviewed by a doctor. Unfortunately, until you get to the medical appointment, no one is going to be able to say why this may be happening.

It may be that others come forward with their own experiences but do remember that these are individual to them.

Take care and if you find it helpful to talk things through with one of the nurses on our helpline the number to call is Freephone 0808 800 4040. The lines are open from 9 am till 5 pm, Monday to Friday.

Sarah.
