Osteosarcoma: Symptoms, Causes, Diagnosis, and Treatment | AIROC Hospitals

About Osteosarcoma – Overview and Types

Osteosarcoma is the most common type of bone cancer, developing from cells that normally form new bone tissue. It most frequently affects children, teenagers, and young adults, particularly during periods of rapid bone growth, though it can occur at any age. At AIROC Hospitals, our orthopedic oncology specialists provide comprehensive, limb-preserving treatment for osteosarcoma, combining advanced surgical techniques with coordinated cancer care.

Osteosarcoma most commonly develops in the long bones of the body, particularly around the knee and upper arm, areas where bones grow quickly during adolescence. Because early symptoms can resemble common growing pains or sports injuries, timely evaluation is essential for accurate diagnosis and effective treatment.

Types of Osteosarcoma

Osteosarcoma is classified based on where within the bone it develops and how the cells appear under the microscope:

• Conventional (High-Grade) Osteosarcoma – The most common type, typically arising within the bone and growing aggressively; further subdivided into osteoblastic, chondroblastic, and fibroblastic subtypes based on cell appearance.
• Telangiectatic Osteosarcoma – A less common, aggressive subtype characterized by blood-filled cavities within the tumor.
• Parosteal Osteosarcoma – A lower-grade subtype that develops on the surface of the bone and tends to grow more slowly.
• Periosteal Osteosarcoma – Develops just beneath the outer covering of the bone and generally has an intermediate growth rate.
• Small Cell Osteosarcoma – A rare, aggressive subtype that can resemble other small round cell cancers.

Accurately identifying the specific subtype and grade of osteosarcoma is essential for determining the most effective treatment approach, and our specialists at AIROC Hospitals ensure thorough pathological evaluation for every patient.

 

Symptoms and Causes

Common Symptoms of Osteosarcoma

Symptoms of osteosarcoma often develop gradually and may include:

• Persistent bone pain that may worsen at night or with activity
• Swelling or a noticeable lump near the affected bone or joint
• Warmth or tenderness over the affected area
• Limping or reduced use of the affected limb
• Bone that fractures more easily than expected (pathological fracture)
• Limited range of motion in the nearby joint
• Fatigue, in cases where the cancer has spread

Because early symptoms can resemble growing pains or a sports-related injury, especially in active children and teenagers, persistent or worsening bone pain should be evaluated by a specialist rather than dismissed.

Causes and Risk Factors

The exact cause of osteosarcoma is not fully understood, but several risk factors have been identified:

• Rapid Bone Growth: The peak incidence during adolescent growth spurts suggests a link between periods of rapid bone development and increased risk.
• Age: Most commonly diagnosed in children and young adults between 10 and 25 years of age, with a smaller second peak in older adults.
• Height: Taller-than-average children and teenagers appear to have a slightly increased risk, consistent with the link to bone growth.
• Previous Radiation Therapy: Prior radiation treatment to a bone, often for another cancer, can increase the risk of developing osteosarcoma in that area later.
• Genetic Conditions: Certain inherited conditions, such as hereditary retinoblastoma and Li-Fraumeni syndrome, are associated with a higher risk of osteosarcoma.
• Paget's Disease of Bone: A condition affecting older adults that increases the risk of osteosarcoma developing in affected bones.

Understanding these risk factors helps our team at AIROC Hospitals guide appropriate evaluation, particularly for patients with relevant medical or family history.

 

Diagnosis and Treatment

How Osteosarcoma Is Diagnosed

At AIROC Hospitals, we use a comprehensive diagnostic approach to confirm osteosarcoma and determine its extent:

• X-Ray: Often the first imaging test used to identify abnormal bone changes suggestive of a tumor.
• MRI: Provides detailed images of the tumor's size and its relationship to surrounding muscles, nerves, and blood vessels.
• CT Scan: Helps assess bone detail and check whether the cancer has spread, particularly to the lungs.
• Bone Scan or PET Scan: Used to determine whether the cancer has spread to other bones or areas of the body.
• Biopsy: A tissue sample is examined to confirm the diagnosis and identify the specific subtype and grade of osteosarcoma.
• Blood Tests: Certain markers, such as alkaline phosphatase, may be elevated and support diagnosis, though they are not definitive on their own.

Treatment Options at AIROC Hospitals

Treatment for osteosarcoma typically involves a combination of therapies tailored to the tumor's location, size, and stage:

• Chemotherapy: Usually given before surgery to shrink the tumor and after surgery to eliminate any remaining cancer cells, forming a central part of standard treatment.
• Limb-Sparing Surgery: Aimed at removing the tumor while preserving the affected limb whenever possible, often using specialized techniques and implants to restore function.
• Amputation: Considered in select cases where limb-sparing surgery is not feasible, followed by rehabilitation and prosthetic fitting.
• Surgery for Metastatic Disease: Including removal of tumors that have spread to the lungs, which is common in osteosarcoma.
• Targeted and Emerging Therapies: Newer treatment options under continued study for patients with recurrent or treatment-resistant osteosarcoma.
• Rehabilitation Support: Physical therapy and rehabilitation services play a key role in helping patients regain strength and mobility after treatment.

Our multidisciplinary team at AIROC Hospitals — including orthopedic oncologists, pediatric specialists, and rehabilitation therapists — works closely together to design a treatment plan focused on effective cancer control while preserving function and quality of life.

 

Prevention and Risk Factors

Because osteosarcoma is closely linked to factors such as age and rapid bone growth that cannot be changed, there is currently no established way to prevent it directly. However, the following can support early detection:

• Awareness of Persistent Bone Pain: Ongoing bone pain, swelling, or limping in a child or teenager — especially if it worsens at night or doesn't improve with rest — should be evaluated promptly.
• Prompt Medical Evaluation: Early diagnosis significantly improves treatment outcomes and increases the likelihood of successful limb-preserving surgery.
• Monitoring for High-Risk Individuals: Those with genetic conditions associated with osteosarcoma, such as hereditary retinoblastoma, may benefit from increased awareness and monitoring.
• Follow-Up After Radiation Therapy: Individuals who have previously received radiation therapy to a bone should maintain regular follow-up care.

At AIROC Hospitals, we emphasize the importance of timely evaluation for persistent bone pain or swelling in children and young adults, as early diagnosis plays a critical role in achieving the best possible outcomes in osteosarcoma treatment.
