Small ball In chest?

[Aiden217]

Ok I'm kind of scared af right now because I'm afraid this is the start of a tumor but here's the situation. I have a small ball in my left chest three inches below my nipple and close to my armpit. I could feel it just today, 2 days earlier I started feeling this dull, bruise-Like feel in that area of my chest. Any pressure made it hurt. Today I can actually feel it. It's very small but hard. It's not at the surface, it feels pretty deep. It's moveable and is getting more painful, it's a dull pain all around it. Using my left arm at all triggers slight pain. So what could this be? Should I be worried or what?

You didn't mention your age. Are you male or female? Breast cancer is very common in women, but men can have it as well. Whatever your age or gender breast cancer should be ruled out.

You should make it more clear. Is it super close to your armpit or is it closer to your nipple? If its closer to your armpit, it could be an infected lymph node (a part of the body that produced white blood cells -- found in both armpits and also near the v-line of the abdomen). Your body could be fighting off a virus of some sort like a cold or flu. If its closer to your nipple, (considering your a woman) it could be a sign of a benign tumor or possibly even a cancerous lump. But don't fear for the worst! Just check with a physician to make sure its nothing serious - doesn't hurt.
