Do stretch marks on breasts mean they are growing?
Sudden weight fluctuation, including pregnancy and growth spurts, can cause breast stretch marks. Weight gain is associated with increased fat and connective tissue, which causes breast size to grow and leads to the development of stretch marks. Why do I have stretch marks on my boobs but they aren't growing? Dehydration can lead to the sudden appearance of red lines or marks on your breasts. Sometimes, birth control pills can trigger a sudden change in hormone levels, causing your body to develop stretch marks even if you aren't pregnant or experiencing puberty.
