Medicines for Bone cancer

What it is

Primary bone cancer is a rare type of cancer that begins in the bones (as distinct from cancer that has spread to the bones from elsewhere, which is more common and is called secondary or metastatic bone cancer). There are several types of primary bone cancer, including osteosarcoma, Ewing sarcoma, and chondrosarcoma; some types are more common in children and young adults, while others are more common in older adults. The exact cause is often not known, though certain factors — such as previous radiotherapy, some rare genetic conditions, and certain bone conditions (like Paget’s disease of bone in older adults) — can increase the risk. The main symptoms of bone cancer are: persistent bone pain, which may be worse at night or with activity and may gradually worsen; swelling or a lump over the affected bone; and sometimes a bone that becomes weak and breaks more easily than expected (a fracture without significant injury), or reduced movement if a joint is affected, along with general symptoms such as tiredness or weight loss in some cases. Because bone pain is very common and usually due to far more ordinary causes (such as injury or arthritis), most bone pain is not cancer — but pain that is persistent, unexplained, worsening, or wakes a person at night, or a persistent lump or swelling over a bone, should be checked, particularly in children, teenagers, and young adults where certain bone cancers are more common. Bone cancer is treated by specialist teams, and treatment depends on the type and stage and may include surgery, chemotherapy, and radiotherapy; outcomes depend on the type and how early it is found.

How it is treated

Bone cancer is diagnosed and treated by specialist teams (in specialist centres), and because it is rare and the symptoms overlap with many common problems, reaching a diagnosis involves careful assessment. Investigations may include X-rays, scans (such as MRI, CT, or bone scans), blood tests, and a biopsy (taking a sample of the bone or lump) to confirm whether it is cancer, what type, and its stage. Treatment depends on the type of bone cancer, its location and stage, and the person’s age and health, and often involves a combination of: surgery to remove the cancer (aiming to remove it completely while, where possible, preserving the limb and function, with reconstruction where needed); chemotherapy (often used before and/or after surgery for certain types, such as osteosarcoma and Ewing sarcoma); and radiotherapy (particularly useful for some types, such as Ewing sarcoma). The specific approach is tailored by the specialist team, and supportive care and rehabilitation (including physiotherapy) are important parts of recovery. Because early diagnosis can improve outcomes, and because certain bone cancers particularly affect children, teenagers and young adults, the key message is to get persistent or unexplained bone symptoms checked: persistent, worsening, or night-time bone pain, or a persistent lump or swelling over a bone, should be assessed by a GP, who can arrange investigations or referral. It is important to keep this in perspective — bone pain is very common and is almost always due to ordinary causes rather than cancer — but symptoms that persist, are unexplained, or are worrying should not be ignored. The reassuring message is that bone cancer is rare, that most bone pain is not cancer, and that specialist treatment is available; the key action is prompt assessment of persistent or unexplained bone pain or a bony lump.
