These little bumps are called Montgomery glands which appear on the areolas or nipples and have nothing to do with breast cancer.These glands are sebaceous glands which produce an oily fluid secreted in small amount to keep the the nipples and areolas lubricated.
Some women make the mistake thinking that these bumps are pustules or pimples and attempt to squeeze them.This is definitely not something that should be done, because it could lead to infection.
On the other hand, true pimples,(aside Montgomery gland),are common and can appear on your nipple area as on any other part on the body.They can occur for various reasons, from pores clogged with dead skin and oil, to bacterial infection and also from stress and hormones.
Usually these types of pimples go away on their own and are not an indication of breast cancer,especially because they are present bilaterally.Apply warm compresses,keep the area clean and wash with an antiseptic soap. However,if you feel pain, redness or swelling, you should see a dermatologist so this condition can be treated,whether it's a Montgomery glands,or pustules infection.
