Cancer of the sternum is a rare malignancy that primarily affects the breastbone, often requiring complex diagnosis and multidisciplinary treatment.
Understanding Cancer Of The Sternum
Cancer of the sternum is an uncommon form of cancer that originates in or spreads to the breastbone, medically known as the sternum. This flat bone lies at the center of the chest and plays a vital role in protecting vital organs such as the heart and lungs. Unlike more common cancers that start in soft tissues or organs, sternum cancer involves bone tissue or adjacent structures, making it particularly challenging to diagnose and treat.
The rarity of this cancer means it is often overlooked or mistaken for other chest wall tumors. It can arise as a primary bone cancer, such as osteosarcoma or chondrosarcoma, or result from metastases—cancer cells spreading from other parts of the body like the breast, lung, or prostate. The sternum’s unique anatomical position complicates surgical intervention and requires careful planning to preserve chest stability.
Types of Cancer Affecting the Sternum
Cancer involving the sternum can be broadly categorized based on its origin:
Primary Bone Cancers
Primary cancers originate directly within the sternum’s bone tissue. The most common types include:
- Osteosarcoma: A malignant tumor producing immature bone cells, mostly affecting younger individuals.
- Chondrosarcoma: Develops from cartilage cells; more frequent in adults and tends to grow slowly but is resistant to chemotherapy.
- Ewing’s Sarcoma: A rare but aggressive tumor often seen in adolescents and young adults.
Secondary (Metastatic) Tumors
Secondary tumors occur when cancer spreads from another primary site to the sternum. Common sources include:
- Breast Cancer: Frequently metastasizes to bones including the sternum.
- Lung Cancer: Can invade nearby bones like the sternum during advanced stages.
- Prostate Cancer: Known for bone metastases, sometimes involving the chest wall.
Understanding whether cancer is primary or secondary impacts treatment decisions significantly.
Symptoms That Signal Sternum Involvement
Symptoms of cancer of the sternum can be subtle initially but tend to worsen over time. Early detection depends on recognizing these signs:
Pain
Persistent pain localized over the breastbone is one of the earliest symptoms. It may start as mild discomfort but intensifies with movement or pressure.
Swelling or Mass Formation
A noticeable lump or swelling on the front chest wall might appear as tumors grow through soft tissues.
Respiratory Issues
Due to proximity to lungs, patients may experience shortness of breath or coughing if cancer invades surrounding structures.
Fractures or Bone Weakness
Cancerous lesions weaken bone integrity, increasing fracture risk even with minor trauma.
Systemic Symptoms
Unexplained weight loss, fatigue, and fever may accompany advanced disease stages.
Because these symptoms overlap with other conditions like infections or trauma-related injuries, thorough evaluation is critical.
Diagnostic Approaches for Cancer Of The Sternum
Accurate diagnosis combines clinical examination with advanced imaging and biopsy techniques.
Imaging Techniques
| Imaging Modality | Description | Role in Diagnosis |
|---|---|---|
| X-ray | A basic radiograph providing initial visualization of bone abnormalities. | Detects bone destruction or abnormal growth but lacks detail on soft tissue involvement. |
| CT Scan (Computed Tomography) | Detailed cross-sectional images offering high resolution views of bone and adjacent tissues. | Aids in assessing tumor size, extent, and involvement with surrounding structures. |
| MRI (Magnetic Resonance Imaging) | Uses magnetic fields for detailed soft tissue contrast without radiation exposure. | Excellent for evaluating marrow infiltration and soft tissue extension around the sternum. |
| PET Scan (Positron Emission Tomography) | A nuclear medicine scan highlighting metabolically active cancer cells via radioactive tracers. | Helps detect metastatic spread beyond primary site and assess treatment response. |
Tissue Biopsy
Confirming malignancy requires obtaining a tissue sample through needle biopsy or surgical excision. Pathologists analyze cellular features under a microscope to identify cancer type and grade. Immunohistochemistry tests may further classify tumor origin when metastasis is suspected.
Treatment Modalities for Cancer Of The Sternum
Managing cancer of the sternum involves tailored approaches depending on tumor type, stage, patient health status, and presence of metastasis.
Surgical Intervention
Surgery remains a cornerstone when feasible. It typically involves radical resection of affected bone segments along with surrounding soft tissues. Due to structural importance of the sternum in chest wall stability:
- Sternal Reconstruction: Post-resection reconstruction using synthetic meshes or muscle flaps is often necessary to maintain respiratory mechanics.
- Lymph Node Dissection:If regional lymph nodes are involved, removal may be performed simultaneously.
Complete surgical excision offers best chances for cure in localized primary tumors but may not be viable in widespread metastatic disease.
Chemotherapy and Radiation Therapy
Chemotherapy employs drugs targeting rapidly dividing cells systemically. Its effectiveness varies by cancer subtype:
- Ewing’s Sarcoma: Responds well to multi-agent chemotherapy regimens combined with surgery/radiation.
Radiation therapy uses high-energy rays focused on tumor sites to destroy malignant cells:
- Palliative Radiation: Relieves pain and controls local tumor growth when surgery isn’t possible.
Both treatments are frequently combined in multimodal protocols enhancing survival rates.
The Prognosis Landscape: What To Expect?
Survival outcomes hinge on several factors including tumor type, stage at diagnosis, treatment responsiveness, and patient overall health.
- Primary Bone Tumors:
Osteosarcoma patients have seen improved long-term survival rates exceeding 60% with aggressive multimodal therapy. Chondrosarcomas generally have better prognosis if completely excised early but show resistance to chemotherapy.
- Metastatic Disease:
Cancer spreading from other sites usually indicates advanced disease with poorer prognosis. Treatment focuses more on symptom control than cure.
Early detection dramatically improves chances since localized tumors can be surgically removed before spreading systemically. Regular follow-ups post-treatment monitor recurrence risks closely.

Cancer of the sternum is a rare malignancy that affects the breastbone. It can originate in the bone itself or spread from other cancers, such as breast or lung cancer. This type of cancer is challenging to diagnose due to its rarity and location.
What types of Cancer Of The Sternum are most common?
The most common types include primary bone cancers like osteosarcoma, chondrosarcoma, and Ewing’s sarcoma. Secondary cancers occur when tumors from other parts of the body, such as breast or prostate cancer, metastasize to the sternum.
What are the symptoms of Cancer Of The Sternum?
Early symptoms often include persistent pain localized over the breastbone. Swelling or a lump on the chest wall may also develop as the disease progresses. These signs warrant prompt medical evaluation for accurate diagnosis.
How is Cancer Of The Sternum diagnosed?
Diagnosis typically involves imaging studies like X-rays, CT scans, or MRI to assess bone involvement. A biopsy is essential to confirm cancer type and origin, guiding appropriate treatment strategies.
What treatment options are available for Cancer Of The Sternum?
Treatment depends on whether the cancer is primary or metastatic. It often involves surgery, chemotherapy, and radiation therapy. Due to the sternum’s critical location, multidisciplinary care is crucial to preserve chest stability and function.
Cancer Of The Sternum | Final Thoughts And Takeaways
Cancer of the sternum stands out due to its rarity and anatomical challenges. Recognizing persistent chest pain or swelling early can prompt timely investigations preventing delayed diagnosis. Multidisciplinary care involving oncologists, surgeons, radiologists, and pain specialists ensures comprehensive management tailored uniquely for each patient’s condition.
