Will a big mole on central chest surgically removed leave a hypertrophic or keloid scarc? what are the risk factors?

Look at other scars: This is best determined by examining your other scars. If you tend to develop raised, red scars, you are more likely to continue. Areas on the central chest tend to have more tension when closed, meaning the scar is more likely to spread a bit (creating a slightly wider scar). You can decrease scar hypertrophy by massaging it beginning at 2 weeks after healing and by wearing sunscreen.
