Hello Merrymaid and thank you for your post.

I am sorry to hear that you are going through breast cancer treatment. I am afraid I really don't know why you have some fluid gathering in your stomach area, it would be a good idea to mention this to your breast team when you next see them or earlier if you are concerned. I wonder if your weight gain is not related to this fluid you feel but due to an overall increase in your weight. Also if you are comparing this weight with another weight taken on a different set of scales remember there is nearly always a difference.  

I hope you will be okay.

Please get back to us if you need any more information or support.  You may find it helpful to talk things through with one of the nurses on our helpline.  The number to call is Freephone 0808 800 4040 and the lines are open from 9am till 5pm Monday to Friday.

Take care,

Caroline
