[|Human|] My 13 year old is a B cup breast size and has developed a 2 cm round x 1cm deep hard lump in her left breast. it was sore and red so I took her to the doctors. She is waiting to have an ultrasound done on it. Do you think it might be a cyst. How common is this in young girls?
[|AI|]  Hi there.regarding your concern, breast cysts are very common in women >35yrs of age. But you will also find cases of cysts quite common in adolescent girls between 10-18 and in boys with gynecomastia. If the lump is hard painful, and red are signs of inflamed cyst.  Many a time could also be asymptomatic. An ultrasound is the IOC for a breast cyst. If positive then can go ahead for diagnostic tests for any hormonal imbalance. If the cysts is infected antibiotics and I&D is advised. most of the time if it is not a cyst then you needn't worry as it could be due to puberty changes and hormonal imbalance. Hence nothing to panic :) hope this helps.
