From your first “WTF is that?” moment, through to some or all of the following procedures, this can be a very stressful time. The key is to try not to let it occupy your mind 100% of the time. Also know that in young women, there are many explanations for breast lumps and change in appearance, including, but not limited to, fibroadenomas (benign growths), cysts and infections. That is not to say that you shouldn’t get anything suspicious checked out – because you should! Breast cancer rates are very low in women under 40, but it does happen, so any lump or change in the appearance of your breast (redness, dimpling skin, nipple changes) should always be checked by a doctor.
