Bone Cancer

At a Glance

Bone cancer refers to malignant tumors that originate in the bone and is distinguished from cancers that have metastasized to the bone from other organs.

Osteosarcoma can appear around the knee or upper arm during adolescence, chondrosarcoma primarily occurs in adulthood, and Ewing sarcoma can appear in children and adolescents.

How the Disease Works

Types of bone cancer, such as osteosarcoma, chondrosarcoma, and Ewing sarcoma, differ in their tissue of origin and clinical characteristics.

In bone cancer, abnormal cells proliferate in the bone and can invade surrounding tissues or spread to other parts of the body.

Patterns Vary by Person

The risks and prognosis of the disease may vary depending on the tumor type, site of occurrence, age, extent and grade of the tumor, genetic background, and previous radiation exposure.

Broad framework of diagnosis and management

The most common symptom is bone pain, and depending on the location and size of the tumor, swelling, limited range of motion, or fractures may occur.

Diagnosis proceeds through a process of identifying the lesion via physical examination and imaging tests, followed by confirming the type through biopsy and pathological examination, and evaluating for metastasis.

Current stage of treatment

Since it may be difficult to distinguish the lesion from benign lesions or bone metastases from other cancers using imaging tests alone, biopsy results must be interpreted together with clinical and imaging information.

Management is planned in coordination with departments such as Orthopedic Surgery, Medical Oncology, Radiation Oncology, Radiology, and Pathology, tailored to the type and extent of the tumor.

Surgery is a key pillar of treatment, and chemotherapy, radiation therapy, or amputation may be considered depending on the type and situation of the tumor.

How to read clinical trials

Since bone cancer can recur after treatment, it is important to undergo regular follow-up examinations according to the schedule determined by the medical staff.

Points to verify in clinical encounters

In clinical practice, one must confirm the accurate type, location, and stage of the tumor, biopsy plans, treatment goals and side effects, follow-up schedules, and eligibility for clinical trials; if there is severe pain, suspicion of sudden fracture, or neurological symptoms, contact medical staff or the local emergency medical system immediately.
