So I've never been worried about cancer. Until today, I was in the shower doing my normal clean when I noticed there is a very small, hard lump underneath the skin near my anus. It feels like it could move with the skin a bit, it's about the size of a pebble. Here is the thing, I have had a few (maybe 3-5) hemorrhoids (external) in my life (I'm 26), and even though this feels like a small circular pebble, I'm wondering if it could be one that's healed overtime. It does not hurt, there is no real pain in the area. Can any body relate? Freaking out a bit here.
