Is it possible for young girls or men to get breast cancer?

It is rare for adolescent girls to get breast cancer but it is possible for young women to have breast lumps that are not cancerous. Although breast cancer is more common among women, it can also occur in men. Since men also have breast tissues, they can develop breast cancer as well.
