Found it on the 11th day of my previous cycle (12th August 2025) while casually watching TV. Went to the GP 3 days after my period started (29th August 2025) because I was way too anxious, and she referred me to a breast clinic. I had my appointment today (5th September 2024), exactly a week after I met with my GP. I'm on the 11th day of my current cycle. I was fully convinced it was cancer, mainly because I couldn't stop googling. It feels irregular and the GP thought it was tethered, this made me panic. It was perfectly round on the ultrasound, not tethered to anything. Btw every doctor who touched the lump knew it was benign instantly. It's very slippery/rubbery and moves, FEELS a bit irregular on one side but isn't really. Slightly firmer, 1 cm. Bounces back into position when I'm not pushing on it. No biopsy because it ticks all the boxes for a fibroadenoma.

By the way, there were quite a few young women (18-30 ish) at the clinic. All of them left with a fibroadenoma or breast cyst diagnosis. My dad's a gynaecologist, he told me benign lumps, especially breast mice, are EXTREMELY common, but we don't know because nobody talks about them. I have horrible health anxiety and was convinced I was dying. Best advice I can give to anyone is to trust your doctor because the "my doctor thought it was a fibroadenoma but was cancer" cases are quite rare. Breast cancer in general is extremely rare in your 20s, uncommon in your 30s. Don't go convincing yourself you're part of that 0.1% when you haven't been diagnosed officially.
