My 10yr Boy Has Lump In His Nipple, Why?

Be a sign of puberty. Boys as young as 10 can start to see signs of their Sexual Maturity Rating reaching level three or four during which lumps in nipples are common. This is the same stage that during which the penis gets longer, pubic hair darker, the testes get larger and boys will start to grow much taller at a fast rate. During this time many adolescent boys develop gynecomastia, this is true mammary breast tissue. Lumps may appear in one nipple, both nipples or under the two at different rates or sizes. 90 per cent of the time, these lumps will disappear of their own accord and it is unusual for them to last more than two years.

There are symptoms that you should look out for to ensure that these lumps are nothing more to worry about. You should consult a doctor if: They are not directly under the nipple; there is any overlying dimpling of the skin, skin ulceration or change in the colour of the skin; if they feel fixed to the skin; if they are large (over 1.5 inches or 4 cm in diameter); if they don’t go away within 2 years; if the nipples leak milk, blood, pus, or other fluid; if there are other signs of diseases - night sweats, fever or weight loss. If your son is suffering from any of these symptoms it is important to get his nipples examined. You should also consider having regularly scheduled physicals throughout his adolescent years. If the breast lump is associated with any other signs of infection, such as sudden increased size, warmth, tenderness, drainage, redness or fevers, then you should consult a doctor as soon as you can.

Puberty varies in every adolescent and can have all sorts of side effects. If you have any concerns about your son then it is worth seeking the advice of a doctor, if only to put both of your minds at ease.

Hi I am 12 I have the same problem but also have many solutions first if all keep up your hygeine take a bath every day( if not every other day) spray deodorant on your self also try to do some running exercise to reduce the pain every day littler pain you will feel and soon only small pain like me it is caused because of puberty when your body grows and changes including your nipples so there you go if your still scared dint be ashamed tell your mom or someone go to doctor and check it out he will re assure you it's a normal process for 10 - 19 year olds

I'm 13 about to be 14 and I Have It under my one nipple and its been there about a year and it grew like a tiny bit but I thought it was cancer but...If it was I'd be dead by now so...It can't be that bad because It's probably Puberty, Hormones, Turn'n into a Man HAHAHAHA!

Hi, I have just discovered a lump under niple of my 11 yr old boy, it is tender and has grown within a week, he is very slim and fit and eats a healthy diet. I have had breast cancer myself three and half years ago so I'm obviously concerned. Saw the doctor four days ago and he is referring  to paediatrician due to my history. I have been reading lots on Internet and it seems to be very common for boys to develop lumps under nipple at this age, but it best to get it checked out.

Well my name is kmar and I live in the US and I just spotted this lump in my right nipple and I just spotted it today and I got a little scared because I have heard of male breast cancer so I really got scared but I researched it and they said it was a sign of puberty and hormones but I am still going to the doctor because I may be a 12 year old boy but I take these things very seriously.

Believe it or not males have problems with their nipples too. It could be something to do with hormones, puberty, infection or reaction to stress. It may be something very simple, but if it concerns you consult a physician.

Its just puberty and is just growing but if I were you I would call a doctor just in case

Well I am a 12 year old boy and I too have a lump in my nipple. Ive researched and I guess its okay. Its just puberty.

I'm 12 and just to night I just descovered a lump under my nipple and I'm consernd and it herts a little bit and I can't see it should I be consernd oh and I'm a boy if it will help

Hi there, I am currently fourteen years old and has discover a 1cm by 1cm lump under my left nipple. Although it takes many years to go through puberty, I am well on my way so I do not understand how I could receive such a lump. I am concerned because through generations of my family, family members have passed away due to cancer, my mom has recently discovered a lump in her breast as well. I am very nervous but when I searched for more information, all these articles were brought to my attention. It seems to be that every 1/500 young, male teenagers who have discovered a lump is due to a disease or cancer. No matter what, I will be seeking medical attention, but if you have any suggestions just to calm me down, that would be great. Thank you

Int to the doctors about it its just a thing that all boys go through from the ages 9-15 but if you hurt it or hit it than it can stay there for a while and it can hurt you if you hurt it.

I am 14 and I have 1on each nipple I am not scared because it is a puberty thing the left side is bigger than the right deffo

I'm 11 I have one that has grown in 4 days and I am seeing a doctor tomorrow, but my research has shown hormonal displacement (puberty), but guys don't take my word for it. It could be anything from cancer to puberty. SEE A DOCTER PLEASE!!!!!!"""

I have it too and I'm fourteen years old. My Doctor says it's just puberty and they aren't getting very big. (Phew it's not an ulcer!) Just make sure no one gives him a nipple cripple!
