Breast cancer is one of the most common cancers affecting women worldwide. Although it can also occur in men, the disease is far more common among women. Health experts say early detection significantly improves the chances of successful treatment and survival.
Not every breast change is caused by cancer, but recognising possible warning signs and seeking prompt medical evaluation can make a critical difference.
1. A New Lump in the Breast or Underarm
A lump is one of the most well-known signs of breast cancer.
While many breast lumps are non-cancerous, any new lump that feels hard, irregular, or does not go away should be examined by a healthcare professional.
Lumps may also develop in the underarm due to swollen lymph nodes.
2. Changes in Breast Size or Shape
A noticeable change in the size or shape of one breast that is not related to pregnancy, breastfeeding, or the menstrual cycle may require medical assessment.
3. Skin Dimpling or Thickening
Breast cancer can sometimes cause the skin to appear dimpled or resemble the texture of an orange peel.
Any persistent skin changes should be evaluated promptly.
4. Changes to the Nipple
Warning signs involving the nipple include:
- A nipple turning inward (inversion) when it was previously outward.
- Persistent pain in the nipple.
- Changes in the appearance of the nipple without an obvious cause.
5. Unusual Nipple Discharge
Nipple discharge that occurs without squeezing the breast especially if it is bloody or occurs from only one breast should be assessed by a healthcare professional.
While discharge can have harmless causes, it may also indicate an underlying breast condition.
6. Persistent Breast Pain
Breast pain is common and is often linked to hormonal changes rather than cancer.
However, persistent pain affecting one area of the breast that does not improve or has no clear explanation should be evaluated.
7. Redness or Swelling
Persistent redness, swelling, warmth, or inflammation of the breast may sometimes indicate an uncommon but aggressive form of breast cancer known as inflammatory breast cancer.
Medical attention should not be delayed if these symptoms occur.
8. Changes in the Skin Around the Breast
Dryness, scaling, crusting, or thickened skin on the breast or around the nipple may be associated with certain breast conditions, including rare forms of breast cancer.
These changes should be examined by a healthcare professional.
9. Swollen Lymph Nodes
Swollen lymph nodes in the armpit or near the collarbone may sometimes appear before a breast lump is noticed.
Persistent swelling should be assessed, particularly if it occurs alongside other breast changes.
10. A Lump That Does Not Go Away
Many breast changes resolve naturally, particularly those related to the menstrual cycle.
However, any lump or unusual breast change that persists for more than a few weeks should be examined by a qualified healthcare professional.
Reducing the Risk of Breast Cancer
Although breast cancer cannot always be prevented, healthy lifestyle habits may help reduce the risk.
Health experts recommend:
- Maintaining a healthy weight.
- Engaging in regular physical activity.
- Limiting alcohol consumption.
- Avoiding tobacco use.
- Breastfeeding when possible.
- Attending recommended breast cancer screening appointments.
Women should also become familiar with the normal look and feel of their breasts so they can recognise any unusual changes.
When to See a Doctor
A healthcare professional should be consulted if you notice:
- A new breast or underarm lump.
- Persistent breast pain.
- Bloody or unusual nipple discharge.
- Changes in breast size, shape, or skin.
- Swelling or redness that does not improve.
Early evaluation does not necessarily mean cancer is present, but it allows any underlying condition to be diagnosed and treated promptly.
The Bottom Line
Breast cancer is most treatable when detected early. Knowing the warning signs including new lumps, nipple changes, skin dimpling, unexplained swelling, and persistent breast pain can help women seek medical attention without delay. Routine screening and awareness of normal breast changes remain important parts of maintaining breast health.
