Hello, I am 19 years old and I have noticed that I have a dimple under my left breast when I raise my arm. This concerns me.

If you have noticed a small dimple or indentation under your left breast when raising your arm, it is important to take note of any changes in its size, shape, or color over time. Although it is always best to consult with a medical professional for an accurate assessment, certain characteristics like irregular shape, multiple colors, diameter larger than 1 cm, or bleeding could indicate a more serious issue. However, if the dimple is small, has a regular shape, and matches the color of your skin, it is less likely to be concerning. It is still advisable to discuss it with your doctor during your next appointment for further evaluation and peace of mind.
