Hi Sabrina2
I just wanted to say that we have a whole set of info for teenagers called breast m8s. It’s aimed slightly younger than you are, but it might be a good starting point: breastcancercare.org.uk/breast-cancer-breast-health/breast-awareness/breast-m8s/
You can find other information about breasts, and what to look for here: breastcancercare.org.uk/breast-cancer-breast-health/breast-awareness/
Don’t forget you can always call our helpline too, and they can talk you through it - 0808 800 6000.
best wishes for you and your mum
Leah
