Sarcoma: What it Is, Symptoms & Treatment

Sarcoma is a rare but serious type of cancer that develops in the body’s connective tissues such as bone, muscle, fat, nerves, or cartilage. While it accounts for a small percentage of all cancers, sarcoma can occur anywhere in the body and affects both adults and children. Early detection and treatment are essential for improving recovery outcomes.

Understanding Sarcoma

Sarcoma refers to a group of cancers that originate in the body’s connective or supportive tissues. Unlike carcinomas, which begin in the organs or glands, sarcomas develop in the bones, muscles, tendons, and fatty tissues. Because these tissues exist throughout the body, sarcomas can arise almost anywhere—from the arms and legs to the abdomen or chest.

Sarcoma cancers are broadly divided into two main categories:

• Soft tissue sarcomas – arising from muscles, fat, nerves, blood vessels, and deep skin tissues.
• Bone sarcomas – also known as sarcoma bone cancer, originating in the bones.

Though rare, sarcomas can be aggressive. Early diagnosis by a specialist at a reputed Surgical Oncology Hospital in Bangalore like SPARSH can make a significant difference in treatment success and long-term outcomes.

Types of Sarcoma

There are over 50 different types of sarcoma, each with distinct characteristics, locations, and treatment requirements. Some of the most common types include:

1. Osteosarcoma

A form of bone sarcoma, osteosarcoma primarily affects the long bones in the arms or legs. It is more common in teenagers and young adults. Symptoms often include localized pain, swelling, and difficulty moving the affected limb.

2. Chondrosarcoma

This sarcoma bone cancer originates in cartilage, the flexible tissue that cushions bones and joints. It usually develops in the pelvis, shoulder, or ribs and tends to affect older adults.

3. Ewing Sarcoma

Common among children and young adults, Ewing sarcoma typically arises in the bones or surrounding soft tissue of the legs, pelvis, or spine.

4. Liposarcoma

A soft tissue sarcoma that begins in fat cells, most often in the thighs or abdomen. It may grow slowly at first but can become aggressive if not detected early.

5. Leiomyosarcoma

This cancer originates in smooth muscles, often found in the uterus, stomach, or intestines. It’s more common in middle-aged and older adults.

Because sarcomas are rare and diverse, accurate diagnosis by an experienced oncologist is essential for determining the most effective sarcoma treatment approach.

Symptoms of Sarcoma

The symptoms of sarcoma cancer vary depending on the type and location of the tumor. In the early stages, sarcomas may not cause noticeable symptoms, making early detection challenging. However, common signs include:

• Lump or swelling: Often painless, but may grow over time.
• Pain: Especially if the tumor presses against nerves or muscles.
• Restricted movement: When sarcomas occur near joints or bones.
• Fatigue and weight loss: Common in advanced cases.
• Fractures: In cases of bone sarcoma, even a minor injury may cause a bone to break.

If you experience persistent pain, swelling, or an unexplained lump, consult a cancer specialist at SPARSH Hospitals — a leading Oncology Hospital in Bangalore — for timely evaluation and diagnosis.

Causes and Risk Factors of Sarcoma

The exact sarcoma causes are not fully understood, but several factors may increase the risk of developing this rare cancer:

• Genetic mutations: Certain inherited conditions, such as Li-Fraumeni syndrome or neurofibromatosis, can increase sarcoma risk.
• Radiation exposure: Previous radiation therapy for another cancer can lead to sarcoma years later.
• Chemical exposure: Long-term exposure to certain chemicals like vinyl chloride or herbicides may raise the risk.
• Chronic swelling (lymphedema): Persistent lymphatic swelling can contribute to soft tissue sarcoma development.
• Age and family history: Some forms of sarcoma are more common in children and young adults, while others affect older individuals.

While these factors can elevate risk, sarcoma can develop without any identifiable cause. Regular checkups and awareness of symptoms are vital for early detection.

Diagnosis of Sarcoma

Accurate diagnosis is crucial for effective sarcoma treatment. At SPARSH Hospitals, our multidisciplinary oncology team uses advanced diagnostic tools, including:

• Physical examination: To identify abnormal growths or swelling.
• Imaging tests: X-rays, MRI, CT scans, and PET scans to determine tumor size, location, and spread.
• Biopsy: A tissue sample is analysed under a microscope to confirm sarcoma type and grade.
• Molecular testing: Detects specific gene mutations that may influence treatment options.

The Best Oncologists in Bangalore at SPARSH Hospitals specialise in comprehensive cancer evaluations to ensure accurate diagnosis and personalised care.

Treatment for Sarcoma

Treatment for sarcoma cancer depends on factors like the type, stage, and location of the tumor. Common sarcoma treatment options include:

1. Surgery

Surgical removal of the tumor is the primary treatment for most sarcomas. Specialists in Surgical Oncology at SPARSH Hospitals use advanced techniques to remove cancer while preserving nearby organs and tissues. Limb-sparing surgeries are often possible, reducing the need for amputation in bone sarcoma cases.

2. Radiation Therapy

High-energy radiation targets and destroys cancer cells. It’s often used before surgery to shrink tumors or after surgery to eliminate remaining cancer cells.

3. Chemotherapy

Powerful drugs are administered to kill or slow the growth of cancer cells. Chemotherapy is especially effective for aggressive sarcoma types like Ewing sarcoma and osteosarcoma.

4. Targeted Therapy and Immunotherapy

These modern treatments focus on specific genetic or molecular features of cancer cells, offering more precise and less toxic treatment options.

At SPARSH Hospitals, patients benefit from advanced technology, compassionate care, and a team of experts in Musculoskeletal Oncology and Surgical Oncology dedicated to achieving the best possible outcomes.

Life After Sarcoma Treatment

Recovery from sarcoma treatment varies depending on the individual and the extent of the disease. Rehabilitation may involve physical therapy, pain management, and emotional support. Regular follow-up appointments are essential to monitor for recurrence and manage long-term side effects.

At SPARSH Hospitals, our integrated oncology program ensures continuous support from diagnosis to recovery, helping patients regain strength and quality of life.

Prevention and Early Detection

While it’s difficult to prevent sarcoma entirely, maintaining overall health and awareness can help:

• Avoid unnecessary exposure to radiation and harmful chemicals.
• Seek medical evaluation for persistent lumps or unexplained pain.
• Stay informed about your family’s medical history and genetic risk factors.

Attend regular checkups at trusted Oncology Hospitals in Bangalore, like SPARSH, for early detection and screening.
