I went to my GP practice to have a sebaceous cyst removed from my scalp. I should have had it done years ago but I ignored it for ages. It didn't seem that big to me, a bit larger than a marrowfat pea, so I thought there'd be a little cut, maybe a couple of cm long at most. It turns out the cyst was actually quite long and only a portion of it was sticking up, so the cut is about 6 cm long. I'm still glad I've had it done, it's just a shame I didn't do it ages ago when it was still relatively small.
It looks quite ugly at the moment, it starts about 1cm back from the hairline above my forehead and stretches back from there. My hair isn't very thick so it's quite noticeable, I don't know whether to wear a hat for a while or just brazen it out.
