Symptoms – Skin Changes
Breast cancer may first appear as changes to the skin of the breast. Changes to the skin may appear as:1
- Dimpling
- Puckering
- Swelling
- Multiple dimples that make the breast skin resemble an orange skin (called peau d’orange)
- Scaly, flaky, or red skin on the nipple or areola (the darkened skin around the nipple)
Any changes to the breast tissue, including changes to the skin, should be discussed with a doctor. While many breast changes are not due to cancer, any change in normal breast tissue should be brought to a doctor’s attention. Additional tests may be needed to determine if the cause is cancer or a non-cancerous condition, including mammography, ultrasound, or biopsy.
Symptoms of inflammatory breast cancer
Inflammatory breast cancer is a rare type of breast cancer that may not form a tumor that can be felt, but causes the breast to look inflamed: red, warm, and swollen. Only 1%-5% of all breast cancers are inflammatory breast cancer. Inflammatory breast cancer may not form a tumor, but the cancerous cells block the lymph vessels, causing the symptoms of swelling and redness.2
Symptoms of Paget disease of the nipple
Paget disease is a rare form of breast cancer that causes changes to the skin of the nipple and areola (the darkened skin around the nipple). The nipple area may appear scaly, flaky, crusty, or red, and the skin can burn, tingle, or itch. There may also be discharge from the nipple. Paget disease of the nipple begins in the milk ducts and spreads to the nipple and areola. Many people with Paget disease also have one or more tumors inside the same breast tissue.3,4
When breast cancer spreads to the skin
In some cases, breast cancer can spread to the skin. This may occur at the time of the initial diagnosis or it may occur as a recurrence of breast cancer. When breast cancer spreads to the skin, it may cause symptoms such as5:
- Persistent rash
- Changes in the color of the skin
- Swelling
- Pain
- Infection, or the appearance of infection
If you notice changes such as these, talk to your doctor.
Other symptoms of breast cancer
Besides changes to the skin of the breast, breast cancers may cause additional symptoms, including:1
- A lump or area of thickened tissue in or around the breast
- Changes to the nipple, such as a turning inward (or retraction) of the nipple
- Changes in the size or shape of the breast
- Discharge from the nipple (other than breast milk), possibly bloody fluid
