Many people are familiar with breast lumps, but there are other symptoms that may indicate early breast cancer. This article describes key early signs to watch for and provides guidance on when to see a doctor.

1. Lumps or bumps in the breast or armpit

• What to Look For: The most common symptom of breast cancer is a lump in the breast or armpit. These nodules are usually painless, firm, and have irregular edges, but can also be soft, round, and tender. Not all lumps indicate cancer, but a new lump or any change in breast feel should be evaluated by a doctor.
• Why It’s Important: A lump is often the first noticeable symptom, and the earlier it is detected, the better the chance of effective treatment.

2. Changes in breast shape or size

• What to Look For: Although it is normal for breasts to change with age, hormonal cycles, and other factors, a sudden change in breast shape or size can be a warning sign. Look for swelling, shrinkage, or unusual asymmetry that persists.
• Why It’s Important: Unexplained changes in breast size or shape may indicate an underlying tumor or inflammation caused by cancerous cells, especially if one breast looks noticeably different from the other.

3. Breast Skin Changes

• What to Look For: Dimples, wrinkles, or a texture that resembles the peel of an orange (called "orange peel") may indicate inflammatory breast cancer or another type of malignancy. The skin may also become red, scaly, or thickened.
• Why It’s Important:While skin lesions are often overlooked, they are sometimes associated with inflammatory breast cancer, a rare but aggressive form of breast cancer that may not be associated with a lump.

4. Discharge from the Nipple

• What to Look For: Any discharge from the nipple, especially if it's clear or bloody, can be a sign of breast cancer. It's especially concerning if it happens without pressing or other external pressure.
• Why It’s Important:  While discharge can have other causes (like infection or hormonal changes), cancerous growths can sometimes cause discharge, especially if the cancer affects the milk ducts.

5. Inverted or Retracted Nipple

• What to Look For: Some people are born with inverted nipples, and this isn't necessarily a cause for concern. However, if you notice that a previously outward-facing nipple is suddenly inverted or retracted, it could be a sign of cancer.
• Why It’s Important: Cancer in the milk ducts can cause the nipple to pull inward, making it look inverted. Sudden nipple inversion requires a doctor's visit.

6. Persistent pain in the breast or nipple

• What to Look For: While early breast cancer is usually painless, some people experience pain or tenderness in the breast or nipple area. This pain may be permanent or intermittent.
• Why It’s Important: Breast pain is often due to a benign condition, but persistent, unexplained pain should not be ignored, as it can sometimes be an early sign of breast cancer.

7. Swelling in the armpit or collarbone area

• What to Look For: Swelling or a lump in the armpit or even near the collarbone may indicate that cancer has spread to the lymph nodes. This symptom may occur even before a breast lump becomes visible.
• Why It’s Important: The lymphatic system is one of the first places breast cancer spreads, so swelling in these areas is an important sign to report to your doctor.

8. Unusual changes in skin temperature or texture

• What to Look For: Some people report that the skin on their breast feels warmer than usual or has an unusual texture, even if there is no noticeable redness or swelling. While this may be due to an infection, it may also indicate inflammatory breast cancer.
• Why It’s Important: Changes in temperature and texture, especially those that persist, should prompt a medical evaluation, as these symptoms may indicate a cancerous lump is growing.
