Itchy breasts are a fairly common occurrence in women, and can also occur in men. Many factors can cause breast itching, ranging from the use of a new soap or detergent, to more serious conditions including very rare cases of a type of breast cancer. Itchy breasts can be persistent, extremely uncomfortable, and sometimes even painful. Pay attention to your symptoms and take steps to treat the itchy areas by using over-the-counter treatment options and by making changes in your lifestyle and products you regularly use. In some cases, you will want to consult with your doctor and have the condition examined, diagnosed, and treated using prescription-strength products.
