The nipples can also provide clues when something changes.
One potential warning sign is a new change in nipple position or appearance. For example, a nipple that previously pointed outward may suddenly become pulled inward.
Some people naturally have inverted nipples, and this can be completely normal. The concern is primarily when inversion or distortion is new and unexplained.
Changes in the skin around the nipple can also occur.
Persistent scaling, crusting, redness, irritation, or changes in the appearance of the nipple or surrounding areola should be assessed, particularly when they do not improve with ordinary care.
Another symptom that can attract attention is nipple discharge.
Nipple discharge has many possible causes. Hormonal changes, pregnancy, breastfeeding, medications, infections, and benign breast conditions can all produce discharge.
However, spontaneous discharge that occurs without squeezing the nipple—especially if it is bloody or comes from only one breast—should be discussed with a healthcare professional.
It is important not to assume that clear or bloody discharge automatically means cancer. The symptom requires assessment because there are multiple possible explanations.
Some breast cancers can affect the ducts behind the nipple, which may produce discharge or other changes.
Pain around the nipple can also occur for many reasons, including hormonal fluctuations, irritation, infection, or benign breast conditions. Persistent or unexplained discomfort deserves evaluation if it does not resolve.
Another unusual symptom can involve the skin of the nipple or areola becoming persistently irritated or crusted. Certain rare breast cancers can produce skin changes around the nipple, but common skin disorders such as eczema can look similar.
This is why diagnosis from appearance alone is unreliable.
If you notice a persistent nipple change, avoid repeatedly squeezing or manipulating the area to see whether discharge appears. Instead, note what you have observed and discuss it with a doctor.
The most useful information includes when the change started, whether it occurs spontaneously, whether it affects one or both breasts, and whether other symptoms are present.
