The scar will be there...
But you need to find out the reason behind the gynaecomastia.
Normal hormone changes are the most common cause of breast development in newborns, boys, and men. There are other causes as well.
HORMONE CHANGES
Breast enlargement is usually caused by an imbalance of estrogen (female hormone) and
testosterone (male hormone). Males have both types of hormones in their body. Changes in the levels of these hormones, or in how the body uses or responds to these hormones, can cause enlarged breasts in males.
In preteens and teens, breast growth is caused by normal hormone changes that occur in puberty. More than half of boys develop breasts during puberty. Breast growth often goes away in about 6 months to 2 years.
In men, hormone changes due to aging can cause breast growth. This may occur more often in overweight men and in men age 50 and older.
