Sarcoma is a type of cancer that develops in the connective tissues of the body, including muscles, bones, tendons, and cartilage. Unlike more common cancers, sarcomas are relatively rare. While sarcomas account for only a small percentage of all cancer diagnoses, they can occur in both children and adults. Their rarity can sometimes make diagnosis and treatment more challenging.

Types of Sarcoma

There are over 150 different types of sarcoma, each with its own unique characteristics.

1. Liposarcoma (Fat Cancer):

Cancer developing in fat cells, commonly found in the deep soft tissues of the thigh.

2. Leiomyosarcoma (Smooth Muscle Cancer):

Cancer originating in smooth muscle cells, potentially occurring in various organs.

3. Fibrosarcoma (Fibrous Tissue Cancer):

Cancer of fibrous tissue, may develop in soft tissues, bones, or organs.

4. Ewing Sarcoma (Bone and Soft Tissue Cancer)

Rare cancer affecting bones and soft tissues, primarily seen in children and young adults.

Who Does Sarcoma Affect?

1. Age Groups Affected

  • Sarcomas can affect individuals of any age, but certain types may be more prevalent in specific age groups.
  • Soft tissue sarcomas often occur in adults, while bone sarcomas may be more common in adolescents and young adults.
2. Gender Distribution
  • Sarcomas do not show a strong gender bias, affecting both males and females.
  • However, specific subtypes may exhibit some variations in gender prevalence.

3. Genetic Predisposition

  • In some cases, a genetic predisposition may increase the risk of developing sarcomas.
  • Individuals with certain inherited syndromes, like Li-Fraumeni syndrome or neurofibromatosis, may have a higher likelihood of developing sarcomas.

Symptoms and Signs

  • Localized Pain or Swelling
    • One common sign is persistent pain or swelling in a specific area.
    • The pain might not be severe initially but can become more pronounced as the tumor grows.
  • Presence of a Lump or Mass
    • Detecting a lump or mass under the skin or in the affected area is a key symptom.
    • The lump may feel firm or tender to the touch.
  • Limited Range of Motion
    • Depending on the location of the sarcoma, individuals may experience limited movement in nearby joints.
    • This limitation can be due to the tumor affecting the surrounding tissues and structures.


  • Genetic Factors
    • Some sarcomas have a hereditary component, with certain genetic mutations increasing susceptibility.
    • Understanding family medical history can provide insights into genetic risk factors.
  • Radiation Exposure
    • Exposure to ionizing radiation, whether from medical treatments or environmental sources, is a known risk factor.
    • Individuals who have undergone radiation therapy for previous cancers may be at increased risk.
  • Environmental Factors
    • While specific environmental factors contributing to sarcoma development are not well-defined, exposure to certain chemicals may play a role.
    • Occupational exposure to certain substances has been associated with an increased risk in some cases.


1. Imaging Tests (MRI, CT Scans)

  • MRI (Magnetic Resonance Imaging):
    • Utilizes magnetic fields and radio waves to create detailed images of soft tissues.
    • Useful in determining the location, size, and extent of the sarcoma.
  • CT Scans (Computed Tomography):
    • Combines X-rays and computer technology to produce cross-sectional images.
    • It helps visualize bones and detect abnormalities in soft tissues.

2. Biopsy:

  • The definitive diagnostic procedure for sarcoma involves the removal of a small tissue sample (biopsy) from the suspected tumor.
  • Types:
    • Needle Biopsy:
      • A thin needle is used to extract a tissue sample for examination.
      • Less invasive and often used for tumors deep within the body.
    • Open Biopsy:
      • Involves a surgical procedure to directly remove a tissue sample.
      • Provides a larger sample for a more detailed analysis.

3. Molecular Testing

  • Purpose:
    • Molecular testing examines the genetic and molecular characteristics of the tumor cells.
  • Benefits:
    • Aids in identifying specific genetic mutations or alterations.
    • Helps determine the most effective treatment options, especially with targeted therapies.
  • Techniques:
    • Polymerase Chain Reaction (PCR):
      • Amplifies specific DNA sequences for analysis.
    • Sequencing:
      • Determines the order of nucleotides in DNA, revealing genetic abnormalities.


1. Surgery

Surgery is the main treatment for sarcomas that haven't spread. It involves removing the tumor.


  • Wide Local Excision:
    • This means taking out not only the tumor but also a bit of the healthy tissue around it. This helps lower the chance of the cancer coming back.
  • Limb-Sparing Surgery:
    • Sometimes, even with tumors near important structures like bones or joints, surgeons can remove the cancer while preserving the limb's function and appearance.
  • Amputation:
    • In cases where it's not possible to save the limb, amputation, or removing the affected limb, might be needed.

2. Radiation Therapy

Radiation therapy uses high-energy rays to target and kill cancer cells.


  • Adjuvant Radiation:
    • After surgery, radiation can be used to make sure any remaining cancer cells are eliminated.
  • Neoadjuvant Radiation:
    • Given before surgery to shrink the tumor, making it easier to remove.
  • Palliative Radiation:
    • This helps with symptoms and controls the growth of tumors, especially when complete removal isn't possible.

3. Chemotherapy

Chemotherapy uses drugs to stop or slow down the growth of cancer cells.


  • Systemic Chemotherapy:
    • These drugs travel throughout the body, targeting cancer cells wherever they might be.
  • Adjuvant Chemotherapy:
    • After surgery, it's used to get rid of any remaining cancer cells.
  • Neoadjuvant Chemotherapy:
    • Given before surgery to shrink tumors and make them easier to remove.

4. Targeted Therapy

Targeted therapy focuses on specific molecules involved in cancer cell growth and survival.


  • Precision:
    • It precisely targets cancer cells, reducing harm to healthy cells.
  • Reduced Side Effects:
    • Compared to traditional chemotherapy, targeted therapy often causes fewer side effects.
Personalized Treatment:
  • It's tailored to the unique genetic and molecular characteristics of the tumor.

Risk Factors

  • Genetic Syndromes
    • Specific genetic syndromes, such as Li-Fraumeni syndrome, hereditary retinoblastoma, and neurofibromatosis, substantially elevate the risk of sarcoma development.
    • In these syndromes, individuals inherit mutated genes that predispose them to various cancers, including sarcomas.
  • Previous Radiation Therapy
    • The risk of sarcoma increases in individuals who have undergone radiation therapy, particularly if the radiation field includes connective tissues.
    • Radiation-induced sarcomas may manifest years after the initial treatment and necessitate careful monitoring.
  • Chemical Exposure
    • Occupational exposure to certain chemicals, such as vinyl chloride and dioxin, has been linked to an increased risk of developing soft tissue sarcomas.
    • Understanding and mitigating workplace exposures are crucial for preventing sarcoma in at-risk populations.


  • Metastasis
    • Sarcomas are notorious for their potential to metastasize, spreading to distant organs and tissues.
    • The likelihood of metastasis varies depending on the sarcoma type and stage, impacting treatment approaches and prognosis.
  • Impaired Function of Affected Area
    • The growth of sarcomas in or near vital structures can lead to functional impairment.
    • For example, a sarcoma near a joint may restrict movement, and tumors affecting nerves may cause sensory or motor deficits.
  • Secondary Cancers
    • Treatment-induced secondary cancers can arise as a consequence of radiation or chemotherapy.
    • Balancing the benefits of treatment with the potential risks, including secondary cancers, is a critical aspect of sarcoma management.


  • Genetic Counseling
    • Genetic counseling provides individuals and families with information about their risk of hereditary cancers, facilitating informed decision-making and personalized surveillance.
  • Avoidance of Known Risk Factors
    • Minimizing exposure to environmental carcinogens, such as industrial chemicals, is essential in preventing sarcoma.
    • Individuals with known genetic predispositions may consider lifestyle modifications to reduce risk.
  • Regular Check-ups and Screenings
    • Regular monitoring, including imaging studies and clinical examinations, is vital for early detection.
    • High-risk individuals, such as those with a family history or genetic predisposition, may benefit from more frequent and specialized screenings.
