It is called umbilical hernia . It can contain fat or part of the small intestine itself . Needs to be fixed surgically or it ll grow big. Stop power lifting , do cardios. Also wear an abdominal support belt.

I know you are anxious about what the lump is. The mere mention of cancer by anyone (doctor, nurse, friend, stranger) scares the hell out of people, and only causes more anxiety, especially when it would be an EXTREMELY rare occurance. \n\nThe best thing I can tell you is to wait for the result from YOUR child's doctor. I know that does not answer your question, but it's probably the most useful answer you'll find on this website. I know you want as much information as possible, as any good mother would. But please, don't torture yourself.

Soft lumps can be found in various parts of the body – it can be lipoma or benign (noncancerous) fatty tumor. The ultra sound that was done by your doctor might confirm this. It is not dangerous to have this. Many people have it. \nBloody stools can mean a lot of things – from hemarroids to gastroenteritis. It could just mean that you had constipation and had a little bleeding. That could be normal. Make a note when it happens again. Were you having blood in your stool or bloody diarrhea? \nHeart pain – usually means pain in the chest area – usually is just gas in the stomach. Just don’t starve yourself. Eat regularly and when it hurts drink water or eat something like yoghurt or fruits. \nDon’t worry about health too much. Sometimes normal things can look like sickness. \nHypochondria is a belief that real or imagined physical symptoms are signs of a serious illness, despite medical reassurance and other evidence to the contrary.

This sounds like an abscess to me, look up Pilonidal abscess or cyst as what you are describing sounds exactly like this.  You can not treat this yourself, you must see a Dr before it gets worse.\n\nI worked in a GP surgery for 7 years and we had a girl who had this, she had to come in a few times a week to have it cleaned and re-dressed.  Don't be embarrassed or worry it is quite a common condition and can be fixed.  \n\nGo and see a Dr to put your mind at rest.

It's a condition called "spina bifida" and it varies in severity.  Some people born with this defect go on to live fairly normal lives while others are profoundly disabled.  The doc who said it's nothing to worry about was probably correct, but there's nothing wrong with getting a second opinion.  The opening might possibly be a portal for infection, but most physicians are familiar enough with the condition that they can be accurate in their estimate of the level of such a risk.  If the parents do choose to have further studies done, they should be aware that MRI is expensive, and depending on circumstances, their insurance carrier may decline the cost.  Best bet - have a second pediatrician examine the child and ask him/her to confirm or contest the first doctor's prognosis.  Don't forget, all of us have an odd little hole in our persons that, in rare instances, can be a problem.  It's called the bellybutton.  I suspect the condition in the child in question is no more serious than is your own bellybutton.

It could be a fatty cyst, a blocked pore, an ingrown hair, a lymph note or a gland.  You need to have it examined by a medical practitioner, rather than have yahoo speculate it for you:)

I DON'T WANNA SCARE YOU AND TELL YOU THAT IT MIGHT BE CANCER BECAUSE AS SOON AS WE HEAR THE WORD LUMP THAT'S WHAT WE ALL START TO THINK. IT COULD BE A ULCER, OR IT COULD BE ANYTHING NONE OF US HAVE GIVING YOU X-RAY'S SO THERE FORE WE WOULD NOT KNOW TRY AND GET SOME X-RAYS BECAUSE THIS CAN SEE YOUR ORGANS AND INSIDE OF YOUR BONES. THEN YOU WILL KNOW WHAT THE REAL PROBLEM IS AND YOU CAN TAKE IT FROM THERE. I HOPE THAT YOU FEEL BETTER AND MY BEST WISHES ARE WITH YOU.

It could be a million things.  Depending on the exact location, it could be your appendix, it could be a kidney stone, or since you are a woman, it could even be a cyst on your ovaries.  It could also be nothing much.  But you need to see a doctor rather than asking the wise-alecks who hang around Yahoo Answers.

you have a lump the size of a lemon and you're asking here what to do?\n\nGet to a Dr whom you trust.  Second opinions are not for nothing!\n\nIf your parents are not terribly concerned, but you are, see your school nurse and let her help you decide what to do.\n\nBest wishes.

It most likely is a harmless cyst if it's been there for that long and hasn't caused any problems.  If it's changed shape or size, though, it may be a cause for concern.  Either way, your doctor should be able to tell you what it is and whether you need to worry about it.  Better to be safe than sorry.

It is an accumulation of stray hairs, clothing fibers, and dead skin cells in the belly button. For some more info, check out the link.

To whom it may concern,\n\nIt could be oarian cyst or it could be that you are pregnant? If I were you, I would go to my doctor and have a pregnancy test done and ask for other tests to come along with it. So that way you can be safe knowing the answers instead of having to do it later in life.

Could be a cyst.  But it also could be stool in your gut.

Could be an umbilical hernia, which requires very minor outpatient surgery to repair. I suggest you see a doctor to find out. Good luck!
