Hi, I'm a 21 year old male. 5 feet 7 inches tall and. I weigh 132 pounds. For about the last two and a half weeks I noticed that my left nipple was extremity tender and puffy and behind I feel a hard lump. After going to the doctor and have an ultra sound and Mammogram done it was determined to be gynecomastia. My question is from these photos, 1) is this a serious case? 2) will the condition worsen? Thank you
