When we think of cancer, bone cancer might not be the first to come to mind, but it’s an important group of diseases that affects people of all ages, especially children and young adults. Among the different types, osteosarcoma, Ewing sarcoma, and chondrosarcoma are the most well-known and impactful. Understanding their differences can help with early detection and better treatment outcomes.

Let’s break down the three major types of primary bone cancers, also known as bone sarcomas.
What Are Primary Bone Cancers (Bone Sarcomas)?
Primary bone cancers are cancers that start in the bone itself, rather than spreading there from other parts of the body. These cancers are also called bone sarcomas, a broader term for cancers that begin in bone, muscle, fibrous tissue, blood vessels, fat tissue, and some other soft tissues. Sarcomas can occur anywhere in the body, but when they originate in bone, they are classified as primary bone cancers.
There are many types of bone sarcomas—some more common than others. Let’s take a closer look at the three major ones before you consult with the best bone cancer doctor in the UAE for treatment:
1. Osteosarcoma: The Most Common Bone Cancer
Osteosarcoma (also known as osteogenic sarcoma) is the most common type of primary bone cancer. It starts in an early form of bone cells, which are the cells responsible for creating new bone tissue.
Who it affects: It most often affects young people, especially those between the ages of 10 and 30. Interestingly, about 1 in 10 osteosarcoma cases occur in people older than 60. It’s rare in middle-aged adults and tends to be more common in males than females.
Where it occurs: Osteosarcomas typically develop in the long bones of the arms and legs, particularly around the knee, as well as in the pelvic bones.
This aggressive cancer often requires a combination of surgery and chemotherapy, suggested by one of the best osteosarcoma doctors, like Dr. Mohamed Mashhour, and early diagnosis is key to improving outcomes.
2. Ewing Sarcoma: Most Common in Youth
Ewing tumors, often referred to as Ewing sarcoma, are the second most common primary bone cancer in children, teens, and young adults, and the third most common overall.
Who it affects: These tumors are rare in adults over 30 and occur most often in white people. They are uncommon among African Americans and Asian Americans.
Where it occurs: While most Ewing tumors develop in the bones, they can also start in other tissues and organs. The most common sites include:
- The hip bones (pelvis)
- The chest wall (such as the ribs or shoulder blades)
- The spine
- The long bones of the legs
Ewing sarcoma often requires aggressive treatment, including chemotherapy, radiation therapy, and sometimes surgery. Because of its tendency to spread early, prompt medical attention from Ewing sarcoma specialists is essential.
3. Chondrosarcoma: Cancer of the Cartilage Cells
Chondrosarcoma begins in early forms of cartilage cells. It is the second most common type of primary bone cancer after osteosarcoma.
Who it affects: Chondrosarcoma bone cancer, is rare in people under 20, and the risk increases with age.
Where it occurs: This type of tumor can start anywhere cartilage is found, but is most often located in:
- Pelvic bones
- Legs and arms
- Sometimes in the trachea, larynx, chest wall, shoulder blades, ribs, or skull
Well, benign (non-cancerous) cartilage tumors, like enchondromas and osteochondromas, are far more common than chondrosarcomas. While these benign tumors rarely turn into cancer, people with multiple such growths may have a slightly higher, but still low, risk of developing chondrosarcoma.
Chondrosarcoma usually doesn’t respond well to chemotherapy or radiation, so surgical removal is typically the primary treatment.

Understanding Types of Bone Cancer- Why It Matters
Although bone sarcomas are rare, knowing the signs, risk factors, and typical age groups affected by each type can help in early detection and prompt treatment. Pain, swelling near bones, or unexplained lumps should always be checked out, especially in children or teens who are still growing.
