What kind of cancer is osteosarcoma?

What kind of cancer is osteosarcoma?

Osteosarcoma is a type of bone cancer that usually develops in the osteoblast cells that form bone. It happens most often in children, adolescents, and young adults. Approximately 800 new cases of osteosarcoma are reported each year in the U.S. Of these cases, about 400 are in children and teens.

Is osteosarcoma a familial tumor?

Osteosarcoma is the most common primary bone tumor affecting predominantly adolescents and young adults. It accounts for about 5% of all childhood cancers. While the majority of osteosarcomas are sporadic, a small percentage occur as a component of hereditary cancer syndromes.

Is osteosarcoma a solid tumor?

Major types of solid tumors Sarcomas are tumors in a blood vessel, bone, fat tissue, ligament, lymph vessel, muscle or tendon. There are many types of sarcomas. They include: Ewing sarcoma and osteosarcoma, which are bone cancer sarcomas.

Is osteosarcoma highly malignant?

Highly malignant osteosarcoma (HMO) is the most frequent malignant bone tumor preferentially occurring in adolescents and children with a second more flat peak in patients over the age of 60.

What is the most reliable sign of early stage osteosarcoma?

The first signs of osteosarcoma are pain and swelling in the affected bone, with symptoms often becoming more severe at night….Other signs of osteosarcoma

• A bump, depending on where the tumor is located.
• Redness and warmth at the site of the tumor.
• Anemia.
• Fever.
• Exhaustion.
• Unexplained weight loss.

  Can osteosarcoma kill you?

  If the disease is localized (has not spread to other areas of the body), the long-term survival rate is 70 to 75%. If osteosarcoma has already spread to the lungs or other bones at diagnosis, the long-term survival rate is about 30%.

  How quickly does osteosarcoma grow?

  The vast majority of osteosarcomas are so-called “random cases”, where no specific causes or predisposing risk factors can be identified. In young people, the development of the tumour appears to be in some way related to periods in life with rapid bone growth, hence the average for tumour development is 14-16 years.

  Is osteosarcoma fast growing?

  High-grade. This is fast-growing cancer. Most osteosarcoma in children is high-grade.

  Is osteosarcoma serious?

  Complications of osteosarcoma and its treatment include: Cancer that spreads (metastasizes). Osteosarcoma can spread from where it started to other areas, making treatment and recovery more difficult. Osteosarcoma that spreads most often spreads to the lungs and to other bones.

  Does osteosarcoma show up in blood work?

  Blood tests. Blood tests are not needed to diagnose osteosarcoma, but they may be helpful once a diagnosis is made. For example, high levels of chemicals in the blood such as alkaline phosphatase and lactate dehydrogenase (LDH) can suggest that the osteosarcoma may be more advanced.

  What happens if osteosarcoma is left untreated?

  If left untreated, primary bone cancer can spread to other parts of the body. Primary bone cancer is also known as bone sarcoma. Secondary (metastatic) bone cancer means that the cancer started in another part of the body, such as the breast or lung, and has spread to the bones.

  Is osteosarcoma always terminal?

  What are the survival rates for osteosarcoma? If the disease is localized (has not spread to other areas of the body), the long-term survival rate is 70 to 75%. If osteosarcoma has already spread to the lungs or other bones at diagnosis, the long-term survival rate is about 30%.

  How do you rule out osteosarcoma?

  How is osteosarcoma diagnosed?

  1. An MRI of the entire bone where the primary tumor is located.
  2. A chest x-ray and CT scan of the chest to detect lung metastases.
  3. A bone scan of the body to rule out distant spread of the disease.

  Is osteosarcoma malignant or benign?

  Malignant bone tumors can occur at almost any age. Osteosarcoma and Ewing’s sarcoma, two of the most common malignant bone tumors, are usually found in people age 30 or younger. In contrast, chondrosarcoma, malignant tumors that grow as cartilage-like tissue, usually occur after the age of 30.

  Where does osteosarcoma usually start?

  In children, teens, and young adults, osteosarcoma usually starts in areas where the bone is growing quickly, such as near the ends of the leg or arm bones: Most tumors develop in the bones around the knee, either in the lower part of the thigh bone (distal femur) or the the upper part of the shinbone (proximal tibia).

  What kind of tumor is a high grade osteosarcoma?

  Other high-grade osteosarcomas include: Extraskeletal: a tumor that starts in a part of the body other than a bone (but still makes bone tissue) These uncommon tumors fall between high-grade and low-grade osteosarcomas. (They are usually treated the same way as low-grade osteosarcomas.)

  Is it possible to have osteosarcoma in any bone?

  But osteosarcoma can happen in any bone, especially in older adults, including your: Bone or joint pain or soreness. This pain may come and go for months. Some limb pain and swelling are common in active, growing children.

  What are the signs and symptoms of osteosarcoma?

  Swelling or lumps around bones or the ends of bones. Bone or joint pain or soreness. This pain may come and go for months. Broken bones that don’t seem to be caused by normal events like a fall.

  What kind of cancer is in the bone?

  Osteosarcoma is a type of bone cancer that usually develops in the osteoblast cells that form bone.

  What is the life expectancy of someone with Stage 4 bone cancer?

  Stage 4 bone cancer life expectancy. About 15 percent cases of bone cancer are diagnosed at stage 4 and bone cancer prognosis indicate nearly 32 percent survival rate at this stage.

  What are the first signs of osteosarcoma, symptoms?

  Signs and symptoms of osteosarcoma may include, among others: Swelling near a bone Bone or joint pain Bone injury or bone break for no clear reason

  How is osteosarcoma treated?

  In most cases, an osteosarcoma is treated using a three-step approach that includes chemotherapy and surgery: First, the patient is given chemotherapy to destroy as much of the tumor as possible before surgery. Next, the patient has surgery. Whenever possible, the doctor removes the cancerous bone without amputating the limb.

  What is the prognosis for spinal bone cancer?

  Survival Rate. The mean survival rate of spinal cancer is up to 40% when treatments are instituted. Some forms may have as low as 8% survival rate and others as high as 84% depending on the location, type and prognostic factors of the patient.
