Hi,
The skin of the breast is like the skin on any part of the body and subject to many abnormalities.The areola and the nipple area have sebaceous glands which can get clogged and form a pimple like lump.You may apply warm compresses,use antibacterial soap and put a little Polysporin ointment and it should go away in a few days.
This pimple like lump is not a sign of breast cancer.However, if the area becomes red,inflamed and painful,you should have your doctor take a look at it, in case it's an infection that needs to be treated with a course of antibiotics.
For dried breast skin,try to use a very mild soap or just wash your nipples with plain water and apply a little Lanolin cream.(with no alcohol).
I really think that you have nothing to worry about, and I sure hope that your OBGYN will also agree.
Best wishes...
