Hi @tea, if breast cancer runs in your family, it’s important to talk your GP (regular doctor) about what kind of screening you should do. Thy might recommend you start mammograms/ultrasound screening earlier. They might recommend genetic testing as well. Sometimes nothing extra is needed — not all breast cancers are hereditary. It’s important to get advice that’s specific to your situation.
No matter family history, I’d recommend that anyone with breasts (including trans women on HRT & trans men who haven’t had top surgery) do self exams just after their period or the same time each month if they don’t have periods.
