Hard knot on one breast

[Blaine0297]

My son, who is 11 noticed about a month ago that he had a small lump that could be felt if pushing in on his right nipple.  I then noticed this morning that the lump has gotten larger.  It is still only at his right nipple, but has increased to be the same size as the nipple and can easily be felt without even pushing in on it.

Its normal. Im 13 and i have that same problem. Although i have bumps on both.  Its normal and happens to 70% of all adolescent boys even if you didnt have this problem as a boy, he can go through this pubertal change. It ***** but tell him itll get better

My 13 year-old son has the same problem with the swollen right breast.I'm still a little skeptical and so is he.Would you reassure us,especially my son.Also he has had  this problem for about 4 months and I need to know if there is anything I can do until his doctors appointment or should we just wait for the doctor.

I think this is a breast bud.  Girls get this at the beginning of puberty, and I remember that I had this.

I did a google search for breast bud, puberty boys, and found alot of information.
"Enlarged or swollen breasts are seen quite frequently in teenage boys. This is called "pre-pubertal gynecomastia". As a boy enters puberty, many hormones are made...
In some boys the levels are so high, the breast gets stimulated to grow by the female type of hormones."

So, this is normal.  It is not a sign of cancer.  
You can have the pediatrician check this.

Wishing you the best,

Hello,

Lumps under the breast in teenage boys(>10 yrs) is extra breast tissue  and can be caused due to change in hormones at adolescence.

There are five stages of the changes that occur during puberty, called Tanner stages or Sexual Maturity Rating (SMR) stages. Breast lumps in boys are common during SMR 3 and SMR 4. The firm lump may occur under only one nipple, under both nipples, or under the two at different rates or sizes. The lumps are often tender when they are growing the fastest. In at least 90% of kids, these will go away on their own. They may disappear as quickly as in a few months, but it is not unusual for them to last up to 2 years (Nelson Textbook of Pediatrics, WB Saunders, 1996).

Consultation is required when they don,t go away after 2years,are large and fixed to skin,is associated with any sort of discharge from the nipple or is associated with weight loss and night sweats.
