You are performing a breast exam on an adult woman. You are inspecting the breasts for signs of retraction. What is the best position to observe for this?

A. This position is useful for inspecting the overall shape and size of the breasts, but it may not be the best for detecting retractions. B. This position can help identify changes in the breast tissue, but it may not be as effective as raising one arm overhead for detecting retractions. C. Raising one arm over the head tenses the muscles in the breast and chest, which can make any retractions more visible. Retraction is often characterized by dimpling or pulling of the skin, which may be more noticeable when the breast tissue is taut. D. This position can be helpful for examining the breasts for other abnormalities, but it may not be the best for detecting retractions.
