What causes dark spots on the collarbone in girls?
I have noticed multiple small black spots around my collarbone area. They are not painful or itchy, but I am very concerned about their cause.

Black spots appearing in the clavicle area may be caused by various factors, including but not limited to pigmentation, moles, freckles, age spots, and melanoma. Pigmentation is often related to sun exposure, while moles and freckles are usually congenital or hereditary, and age spots are associated with aging. However, melanoma is a serious type of skin cancer that, although less common in adolescents, still requires vigilance.
It is recommended to seek timely medical attention to determine the exact cause of the black spots through a professional doctor's diagnosis. The doctor may make a comprehensive assessment based on the black spot's shape, size, color, and any accompanying symptoms, and may require further examinations, such as dermoscopy or histopathological analysis.
