Sore breast, blue veins. could it be sign of breast cancer ?

Mondor's?: My first guess is that if the veins are prominent, it's mondor's and benign. Please do visit your physician now.

Signs & Symptoms: Typical symptoms can include a breast lump or hardness, change is size or shape of breast, inverted nipple, peeling of the nipple or breast skin, changes of breast skin into a pitting nature like an orange peel, and bloody discharge from the nipple. Soreness of breast and enhanced look to the breast in a 21 year old female can be common especially around the menstrual period.

Probably not: These are not common symptoms of breast can. It would also be exceedingly rare of a 19 year old to get breast cancer.

Normal finding: I am amazed about how often I have women ask me about the veins on their breast. Occasionally they are spider veins but mostly they are blue veins. These are usually normal findings and normal variations of chest veins. They tend to be more pronounced in fair skinned females. Occasionally new breast formation may be a sign of an underlying mass. See a vein specialist for an evaluation.
