Doctors will often use a patient’s medical history, physical examination, imaging tests, biopsy results and blood tests to diagnose bone cancer (uncontrolled growth of cells that begins in the bones). Generally, the most accurate way to diagnose bone cancer is through a biopsy.
When taking your medical history, your doctor will ask about symptoms, how they began and whether there is a history of medications or underlying health conditions. Your physician may also inquire about your family history to see whether any of your close relatives, such as parents or siblings, have had cancer.
A biopsy is the most accurate way to diagnose bone cancer or other bone diseases. During a biopsy, a piece of tissue is taken from the tumor and examined in a lab under a microscope. The results can help your doctor determine whether the mass is caused by cancer or other diseases, as well as what type of cancer is present.
Your physician may order blood tests to check for various parameters, such as blood counts, blood sugar, biomarkers (raised levels of certain substances in the blood in case of a tumor) and electrolytes (such as calcium, magnesium and sodium).
What are symptoms of bone cancer?
Bone cancer may cause the following symptoms:
- Bone pain
- Swelling over the bone
- Fractures that occur with minor injury or in the absence of injury
- Unintended weight loss
- Pale skin
- Reduced appetite
- A feeling of being unwell or sick
These symptoms may not necessarily be indicative of bone cancer. For a definitive diagnosis, it is recommended that you have a consultation with your physician.
What are the types of bone cancer?
The three main types of bone cancer are:
- Osteosarcoma: The most common type of bone cancer. About 3% of cancers in children are osteosarcomas. Since osteosarcoma occurs in the bone-forming cells, called osteoblasts, this cancer is seen more commonly in teens or children in age groups where growth spurts happen.
- Chondrosarcoma: The second most common primary bone cancer. It occurs in the cartilage forming cells.
- Ewing sarcoma: This tumor may form in immature nerve tissue in the bone marrow. Ewing sarcoma generally affects the long bones, such as the thigh bone (femur), upper arm bone (humerus) and shinbone (tibia). However, it can affect the pelvic bones as well. When this cancer starts in the muscles and soft tissues, it is called extraosseous Ewing sarcoma.
Some rare types of bone tumors include:
- Fibrosarcoma: A cancer of a type of cell called the fibroblast, and generally affects the hips or knees. Fibrosarcoma may be seen in older people who have undergone radiation therapy for other cancers.
- Chordoma: Usually seen in the tailbone (sacrum).
- Giant cell tumor: A type of noncancerous (benign) but aggressive bone tumor. It typically affects young adults.
- Adamantinoma: Usually seen in the shin bone (tibia) of young individuals.
