I am having abnormal dimples and something that feels like a varicose vein in my breast. should i be concerned?

Yes: Be seen by a breast surgeon. Mammogram and biopsy are possibilities.

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 almost always normal findings and normal variations of chest veins. They tend to be more pronounced in fair skinned females and they may be related to hereditary factors or even pregnancies. No treatment is necessary unless for cosmetics.

Yes: Gsee you doctor and get a mammogram or ultrasound or MRI as soon as possible. Dumpling of the breast is abnormal and needs a diagnosis.
