Breast cancer is the most common cancer affecting women worldwide. While many people associate it with a breast lump, the disease can also present with several other warning signs that are often overlooked. Recognising these symptoms early and seeking prompt medical attention can improve the chances of successful treatment.
Health experts emphasise that breast cancer detected at an early stage is often easier to treat and has a better outcome.
What Is Breast Cancer?
Breast cancer occurs when abnormal cells in the breast grow uncontrollably and form a tumour.
Although it is much more common in women, men can also develop breast cancer.
The disease can begin in different parts of the breast, including the milk ducts, milk-producing glands (lobules), or surrounding tissues.
What Causes Breast Cancer?
The exact cause of breast cancer is not fully understood.
It develops when genetic changes (mutations) cause breast cells to multiply uncontrollably.
Most breast cancers are not inherited, but some are linked to inherited gene mutations such as BRCA1 and BRCA2.
Risk Factors
Several factors may increase the risk of breast cancer, including:
- Increasing age.
- A family history of breast or ovarian cancer.
- Inherited BRCA gene mutations.
- Early onset of menstruation.
- Late menopause.
- Having no children or having a first child later in life.
- Obesity after menopause.
- Excessive alcohol consumption.
- Previous radiation therapy to the chest.
Having risk factors does not mean a person will definitely develop breast cancer.
Symptoms Beyond a Lump
While a breast lump is a common sign, breast cancer may also cause:
- Swelling of all or part of the breast.
- Changes in breast size or shape.
- Dimpling or puckering of the skin.
- Redness or thickening of the breast skin.
- A nipple that turns inward (inverted nipple).
- Nipple discharge, especially if bloody.
- Persistent breast or nipple pain.
- Swelling or lumps under the armpit.
- Skin that resembles the texture of an orange peel.
These symptoms do not always indicate cancer but should always be evaluated by a healthcare professional.
How Is Breast Cancer Diagnosed?
If breast cancer is suspected, your healthcare provider may recommend:
- A clinical breast examination.
- Mammography.
- Breast ultrasound.
- Breast MRI in selected cases.
- A biopsy to confirm the diagnosis.
Additional tests may be performed to determine whether the cancer has spread.
Treatment Options
Treatment depends on the type and stage of breast cancer.
Surgery
Surgery may involve removing only the tumour (lumpectomy) or the entire breast (mastectomy).
Radiotherapy
Radiation is often used after surgery to destroy remaining cancer cells.
Chemotherapy
Chemotherapy uses medicines to kill cancer cells and may be given before or after surgery.
Hormone Therapy
Some breast cancers depend on hormones to grow and can be treated with hormone-blocking medications.
Targeted Therapy and Immunotherapy
Certain women may benefit from newer treatments that specifically target cancer cells or strengthen the immune system.
Can Breast Cancer Be Prevented?
Although not all cases can be prevented, the risk may be reduced by:
- Maintaining a healthy weight.
- Exercising regularly.
- Limiting alcohol intake.
- Avoiding smoking.
- Breastfeeding where possible.
- Attending recommended breast cancer screening.
Women at high risk may require additional monitoring or preventive strategies.
When Should You See a Doctor?
Seek medical advice immediately if you notice:
- A new breast lump.
- Changes in breast shape or size.
- Bloody nipple discharge.
- Persistent breast pain.
- Skin changes on the breast.
- Swollen lymph nodes under the arm.
Do not wait for symptoms to become severe before seeking evaluation.
The Bottom Line
Breast cancer does not always begin with a lump. Changes in the skin, nipple, breast size, or persistent pain can also be early warning signs. Regular breast awareness, routine screening where recommended, and prompt medical evaluation of any unusual changes are essential for early diagnosis and successful treatment.
