This is sometimes referred to as peau d’orange, a French term meaning “orange peel.”
Skin changes can happen for many reasons that have nothing to do with cancer. Allergic reactions, infections, inflammation, injuries, and hormonal changes can all affect the appearance of breast skin.
That is why seeing redness or irritation does not automatically mean that breast cancer is present.
However, persistent or unexplained changes deserve attention, particularly when they occur alongside a lump, swelling, nipple changes, or a change in the shape of the breast.
One particularly important condition doctors consider when there is rapid breast swelling, redness, warmth, and skin thickening is inflammatory breast cancer. This is an uncommon but aggressive form of breast cancer that can develop without producing a clearly defined lump.
The symptoms can sometimes resemble an infection, which makes professional evaluation especially important when changes do not improve as expected.
A woman should not wait indefinitely for a skin change to disappear if it is persistent or worsening.
The goal is not to assume the worst. The goal is to determine what is actually causing the change.
3. Changes in the Nipple or Unusual Discharge
The nipples can also provide clues that something has changed within the breast.
A newly inverted nipple, meaning the nipple begins pointing inward when it previously pointed outward, can sometimes require evaluation. Other changes may include persistent crusting, scaling, unusual irritation, or changes in the surrounding skin.
Again, there are many possible explanations for these symptoms.
Some nipple changes are associated with benign conditions, hormonal changes, skin disorders, breastfeeding, or infection. But a new and unexplained change should not automatically be dismissed.
Unusual nipple discharge is another symptom worth discussing with a healthcare professional.
Nipple discharge can occur for many reasons and is not necessarily related to cancer. Hormonal changes, medications, pregnancy, breastfeeding, and benign breast conditions can all cause discharge.
However, spontaneous discharge—particularly if it occurs without squeezing the nipple, comes from only one breast, or contains blood—can warrant further evaluation.
Women should avoid repeatedly squeezing the nipple to check for discharge because doing so can itself stimulate additional discharge.
Instead, if unusual discharge occurs spontaneously, it is better to note what happened and tell a healthcare professional.
The distinction between normal and abnormal nipple changes is not always obvious to someone examining themselves. That is why medical evaluation can be useful when something appears unusual.
