Hello Fraser,
Welcome to Cancer Chat. We have some information on our About Cancer pages specifically relating to breast cancer in men that I have linked for you here.
You might also like to give our team of nurses a call to chat to them about your questions and concerns. You can call them free from a UK landline on 0808 800 4040 Monday to Friday 9am to 5pm.
Sending best wishes,
Jenn
