I just found a small (pinhead size) lump under the skin near my spencter It's tiny and hard and deep under the skin near my spencter It seems to move a bit when I touch it. I havent seen and blood in stool or any other sighns of cancer but its got my worried. I'm a college student and my medical insurance wont cover to much.
Experiencing additional symptoms along with this lump, will help giving some suggestions for possible diagnosis.
It could be an external hemorrhoid, perianal haematoma (blood blister due to broken blood vessel when the anal sphincter is stretched too much, constipation, straining) or perianal abscess.
Perianal cyst or cancer must be taken in consideration, too.
Physical examination of this area will help your physician making a correct diagnosis.
