The bad abdominal pains could be many different things. That alone could mean you should see a doctor. I’m not a medical authority. The nipple lump sounds like the same thing this message board is for—a cyst related to puberty and something semi-common for both girls and boys. However, mention it to your doctor. I always want to mention that you would do well to learn to communicate with your parents. You’re at the age where parents can seem quite annoying, but they need to learn that you’re growing up and this would be a perfect reminder for them.
I'm 17 and i have something similar.. i have a bump under my nipple and it feels like a marble. It doesn't hurt or anything which makes me believe it's not a cyst.. I'm rlly scared. My breasts are fully developed so idk what it could be..
What you describe is not typical, such as lumps under the nipple. Tell your mom, get a doctor appointment. I am not a medical authority, but seem to know more about these things than most people.
A lump on the surface isn't what I hear of as often as lumps under the surface. You didn't say how large it is or how long you've had it. I'd guess it's a cyst, but my primary recommendation to all youth on this site is to TALK TO YOUR PARENTS.
Not all cysts are painful. With your age and since your preasts are developed, this doesn't sound like a typical cyst. I suggest you find someone to talk to--a school nurse, an aunt, but best is Your Mom. With your age, it's probably not cancer but might be a non-cancerous growth, other than a cyst, which a doctor might want removed. Some growths should be taken care of before pregnancy occurs. Yes, that may be years away for you, but some people forget about such things and the removal needs to be fully healed before pregnancy. I am NOT a medical authority, but feel you ought to see a doctor.
WE cannot tell you what it is. Only a doctor can. Please tell your mom. You can start with, "Mom, I have a bump under my nipple. It's probably a cyst, like many girls AND even boys can get when around my age." IF you can't get yourself to say this to your mom I strongly recommend you find SOME adult woman you feel comfortable talking to about the MANY questions YOU WILL HAVE in the next few years--An aunt, a school nurse, a teacher; a friend's mother.
