Hi tropical moment,
Welcome to the Breast Cancer Care discussion forums where the users of this site have a wealth of knowledge and experience between them and I am sure they will support you and your mum through this.
To help you both along I have put for you below links to a couple of BCC's publications you might find helpful. Also, our freefone helpline is there for you and your mum if you need to talk to someone in confidence. 0808 800 6000.
BC and you:
Chemo for BC: http://www2.breastcancercare.org.uk/publications/treatment-side-effects/chemotherapy-breast-cancer-b...
I hope this helps. Take care,
Jo, Facilitator
