I : I can understand your concern. As this has occurred more than once, please have this evaluated. It sounds like an infectious area such as a small area of a skin infection, but this should be tested and a wound culture taken. It is extremely unlikely that it is cancer, but if you have risk factors and depending on your age it is always wise to get a mammogram. Please see your doctor for evaluation. If you have increased pain, fever, feel flu-like, or have red streaks or increased redness from the area then you must be seen immediately.

Sebaceous cyst: This sounds like an infected sebaceous cyst which is benign and can occur anywhere on the skin. Please get checked by your dr to make sure it is not a breast lump.
