My daughter aged 14 has come to me about a lump in her breast. She is in the early stages of breast development still and It is most likely the bud but not 100% sure. The issue is that it is only on one side and yesterday she reported that the nipple itself was sore. She is now very anxious about this and I have emailed the GP to see if we can get checked over but just trying to reassure her until then.
