What is Sarcoma Cancer? Understand the Causes and Symptoms

Sarcoma cancer (肉瘤癌) is a rare but serious disease that affects the body's connective tissues, including muscles, bones, fat, and blood vessels. Though uncommon, it’s important to understand the causes, symptoms, and preventive measures for sarcoma cancer to increase awareness and improve outcomes for those affected. 

What is Sarcoma Cancer?   

Sarcoma cancer (soft tissue sarcoma) is a type of cancer that begins in the connective tissues, which provide structure and support to the body. Unlike other cancers that typically develop in organs, sarcoma can occur in any body part. However, it is most commonly found in the arms, legs, abdomen, and chest. 

Sarcomas are categorised into two main types: 

1. Soft Tissue Sarcomas: These occur in muscles, fat, blood vessels, and other soft tissues. 
2. Bone Sarcomas: These develop in the bones and include conditions like osteosarcoma and Ewing sarcoma. 

With over 70 subtypes of sarcoma cancer, early detection and treatment are essential to managing the disease effectively. 

Sarcoma Cancer Causes  

The exact cause of sarcoma cancer is not always clear, but several factors can increase the risk: 

• Genetic Mutations: Changes in certain genes can lead to abnormal cell growth, resulting in sarcoma. 

• Inherited Conditions: Genetic syndromes such as Li-Fraumeni syndrome, neurofibromatosis, and familial retinoblastoma increase sarcoma risk. 

• Radiation Exposure: Prior radiation therapy, especially for other cancers, may increase the likelihood of developing sarcoma. 

• Chemical Exposure: Long-term exposure to certain industrial chemicals or herbicides may elevate the risk. 

• Lymphedema: Chronic swelling caused by a blockage in the lymphatic system can occasionally lead to sarcoma in the affected area. 

While these factors can contribute to sarcoma cancer, it’s important to note that many patients have no identifiable risk factors. 

Sarcoma Cancer Symptoms  

The symptoms of sarcoma cancer depend on the type and location of the tumour. Common signs include: 

• A Lump or Swelling: A painless lump in the arms, legs, or abdomen is often the first noticeable symptom. 

• Pain: Tumours pressing on nerves or tissues may cause discomfort or pain. 

• Limited Mobility: Sarcomas near joints can restrict movement or cause stiffness. 

• Bone Pain or Fractures: Bone sarcomas can weaken the bones, leading to pain or fractures with minimal trauma. 

• Fatigue and Weight Loss: Advanced sarcoma may cause persistent tiredness and unexplained weight loss. 

If you experience any of these symptoms, especially a lump that grows over time, it’s essential to seek medical advice for early diagnosis and treatment. 

How to Prevent Sarcoma Cancer

While there is no guaranteed way to prevent sarcoma cancer, taking steps to reduce your risk and maintain overall health can be helpful: 

1. Avoid Excessive Radiation Exposure: Limit exposure to radiation unless medically necessary. 
2. Adopt a Healthy Lifestyle: Eat a balanced diet, exercise regularly, and avoid smoking to boost your immune system. 
3. Manage Stress: Chronic stress can weaken the immune system, so practice relaxation techniques like meditation or yoga. 
4. Monitor Family History: If you have a family history of genetic conditions linked to sarcoma, discuss regular screenings with your doctor. 
5. Regular Check-Ups: Early detection through routine health screenings can significantly improve outcomes. 

What is the Survival Rate of Sarcoma Cancer? 

The survival rate for sarcoma cancer depends on several factors, including the type, stage, and location of the tumour, as well as the patient’s overall health. 

• Soft Tissue Sarcomas: The 5-year survival rate is approximately 65% when diagnosed early, but this can drop if the cancer has spread to other parts of the body. 

• Bone Sarcomas: Survival rates vary depending on the subtype. For example, osteosarcoma has a 5-year survival rate of about 70% when detected early, while advanced cases may have lower rates. 

Advancements in treatment, including surgery, radiation therapy, and targeted therapies, have improved survival rates in recent years. Early detection remains critical for better outcomes. 

Sarcoma cancer is a complex and rare condition, but understanding its causes, symptoms, and risk factors can help with early diagnosis and treatment. While prevention is not always possible, maintaining a healthy lifestyle and staying informed about potential risk factors can reduce your risk. Consult a healthcare professional promptly if you notice any unusual symptoms, such as persistent lumps or unexplained pain.  

Raising awareness about sarcoma cancer can encourage early detection and improve the chances of successful treatment. If you have any questions or concerns, you should speak to a healthcare provider to discuss your condition and options.
