Signs suspicious for metastasis often vary depending on where the cancer has spread in the body.
Recognizing Signs of Metastatic Cancer
Metastasis occurs when cancer cells break away from the original tumor and travel through the bloodstream or lymphatic system to form new tumors in other parts of the body. The symptoms experienced are typically related to the organ or area where the new tumors have formed, impacting its normal function.
Common Signs by Location
The specific signs that are suspicious for metastasis are often tied to the organ or body part where the cancer has spread.
| Area of Spread | Common Suspicious Signs |
|---|---|
| Bone | Pain, Fractures |
| Brain | Headache, Seizures, Dizziness |
| Lung | Shortness of Breath |
Detailed Symptoms of Metastasis
When cancer spreads to different areas, it can manifest with distinct symptoms that warrant medical evaluation, especially in individuals with a history of cancer.
- Bone Metastasis: If cancer cells have spread to the bones, common indicators include persistent pain in the affected area. This pain might worsen over time or with activity. The integrity of the bone can also be compromised, leading to an increased risk of fractures from minor trauma or even without an apparent injury.
- Brain Metastasis: When cancer spreads to the brain, it can lead to various neurological symptoms. These may include recurrent or severe headaches that are not relieved by typical pain medication, seizures, or feelings of dizziness. Other signs might involve changes in vision, speech difficulties, or issues with balance and coordination.
- Lung Metastasis: If cancer has metastasized to the lungs, one of the most common and concerning symptoms is shortness of breath. This can range from mild difficulty breathing during physical exertion to more pronounced breathlessness even at rest. A persistent cough or chest discomfort may also be present.
It is important to remember that these symptoms can also be caused by other, non-cancerous conditions. However, if new or worsening symptoms appear in someone with a history of cancer, or if there are unexplained persistent symptoms, seeking prompt medical attention is crucial to determine if metastasis has occurred.
