Early Signs of Metastatic Breast Cancer to Watch For

Metastatic breast cancer—also called stage IV breast cancer—is when cancer spreads beyond the breast to other parts of the body. Early detection of its first signs can lead to better treatment outcomes. Here’s what symptoms to look out for and when to speak with a medical professional.

What Is Metastatic Breast Cancer?

Metastatic breast cancer occurs when cancer cells from the breast spread to distant organs like the bones, lungs, liver, or brain. Unlike early-stage breast cancer, it cannot be cured, but it can often be managed with treatment to improve quality of life and extend survival.

Common Symptoms of Metastatic Breast Cancer

1. Changes in Breast Appearance or Texture

Look out for new lumps, swelling, or changes in breast shape. Skin dimpling, puckering, redness, or thickening can also signal the spread of cancer.

2. Persistent Breast or Chest Pain

Ongoing, dull, or sharp pain in the breast, chest, or underarm that doesn’t go away may be cause for concern—especially if it worsens over time.

3. Unexplained Weight Loss and Loss of Appetite

Rapid, unintentional weight loss or decreased appetite could indicate cancer spreading to internal organs like the liver or digestive system.

4. Fatigue That Doesn’t Go Away

Feeling constantly drained—even after rest—can be a sign that cancer is affecting your metabolism or other organs. Fatigue that interferes with daily life warrants a medical visit.

5. Shortness of Breath or Chronic Coughing

Difficulty breathing, wheezing, or coughing (sometimes with blood) could suggest the cancer has spread to the lungs.

6. Abdominal or Back Pain

Pain in the abdomen, lower back, or upper spine may result from cancer in the liver or bones. Bloating and digestive changes can also be red flags.

7. Neurological Symptoms

If cancer reaches the brain or spinal cord, symptoms may include:

• Headaches
• Dizziness
• Blurred vision
• Seizures
• Difficulty with coordination or balance

Important Note

These symptoms can also be caused by non-cancerous conditions. However, if you notice any persistent or unexplained changes, contact your doctor for evaluation and imaging.

Treatment Options for Metastatic Breast Cancer

At this stage, the goal of treatment is to control the disease, relieve symptoms, and improve quality of life. Treatment options include:

Systemic Therapy

• Chemotherapy: Targets rapidly dividing cancer cells
• Hormone Therapy: Used for hormone receptor-positive cancers
• Targeted Therapy: Focuses on proteins or genes that drive cancer growth
• Immunotherapy: Helps the immune system fight cancer (for certain subtypes)

Localized Treatments

• Radiation therapy can ease pain or reduce tumor size in the bones or brain
• Surgery may be used to remove isolated tumors or manage complications

Palliative and Supportive Care

Managing symptoms is a crucial part of care. Services may include:

• Pain control
• Counseling and mental health support
• Nutritional guidance
• Complementary therapies like acupuncture or massage
