Hello, and thanks for your post,

Finding any lump can be very unsettling but as the other forum member has suggested try not to jump to any conclusions.

There are many different reasons for lumps to occur and as your doctor suggested it may well be a cyst. Lymph nodes can go up and down when an infection is present. Staying off the internet is a good idea as you will not be able to diagnose yourself.

The majority of women who are referred to breast clinics are found not to have cancer.

The charity Breast Cancer Now has produced some information on benign breast conditions which you may find helpful to look at here

I do hope that you know more soon.

The nurses are on the helpline if you would like to talk any of this through. The lines are open Monday to Friday 9 am to 5 pm and the helpline number is Freephone 0808 800 4040.

All the best,

Catherine
