Bone cancer is a rare condition that includes several types of malignant tumors that start in your bones. It is often difficult to diagnose bone cancer as symptoms can be similar to other conditions, such as injuries, infections, or arthritis. However, if you experience persistent bone pain, swelling, or a lump, it is important to seek medical advice. Doctors will typically use imaging tests such as X-rays, MRIs, CT scans, and bone scans to identify bone cancer and determine its stage. A biopsy, which involves examining a small sample of bone tissue under a microscope, is the most definitive test to confirm a bone cancer diagnosis.

What You'll Learn
X-rays, CT scans, and MRIs can detect bone abnormalities
X-rays, CT scans, and MRIs are all diagnostic imaging techniques that can help detect bone abnormalities. X-rays are the most common and widely available of these techniques. They can show some abnormalities better than more sophisticated tests and are often used to assess fractures. In standard X-rays, a beam of energy is aimed at the body part being studied. A plate behind the body part captures the variations of the energy beam after it passes through skin, bone, muscle, and other tissue. Bones, calcifications, some tumours, and other dense matter appear white or light because they absorb the radiation. Less dense soft tissues and breaks in bone allow radiation to pass through, making these parts look darker on the X-ray film.
Computed tomography (CT) scans are more detailed than standard X-rays and can show the size, shape, and position of structures deep inside the body. CT scans combine many X-ray pictures to make detailed cross-sectional images of the body. CT scans are also useful for looking for possible cancer spread in other parts of the body, such as the lungs, liver, or other organs.
Magnetic resonance imaging (MRI) scans create detailed images of the inside of the body using radio waves and strong magnets instead of X-rays, so no radiation is involved. MRI scans work without radiation and use magnetic fields and a sophisticated computer to take high-resolution pictures of bones and soft tissues. MRI scans can usually show if it’s likely to be a tumour, an infection, or some type of bone damage from another cause. They can also help determine the exact extent of a tumour, as they can show the marrow inside bones and the soft tissues around the tumour, including nearby blood vessels and nerves.

Biopsies are used to confirm bone cancer
While symptoms, physical exams, and imaging tests may suggest that a person has bone cancer, doctors usually need to confirm this with a biopsy. Biopsies are a procedure in which doctors take and test a tissue or cell sample.
Biopsies are important for distinguishing primary bone cancers from cancers that have spread to the bones from other parts of the body (bone metastasis), as well as from benign bone tumours and other types of bone problems. These conditions might require different treatments.
To diagnose bone cancer, healthcare providers often first use X-rays to view the bones. Magnetic resonance imaging (MRI) and CT (computed tomography) scans provide more detailed images of the areas around the bones. To confirm the diagnosis, a biopsy is performed. A small piece of tissue is removed from the bone and examined by a pathologist under a microscope. This provides specific information about the cancer type.
A bone biopsy is a minor procedure performed in the interventional radiology department or operating theatre with the help of an X-ray or scan. The X-ray or scan shows exactly where to place the biopsy needle. A bone biopsy is a highly specialised procedure. Before the procedure, the surgeon or radiologist will explain what will happen and ask the patient to sign a consent form. The patient may also have blood tests and an ECG before the biopsy.

Bone cancer symptoms are often confused with other conditions
Bone cancer can be challenging to diagnose, and it often requires a combination of imaging tests, laboratory tests, and biopsies to confirm. Imaging tests such as X-rays, magnetic resonance imaging (MRI), and computed tomography (CT) scans can provide detailed images of the bones and surrounding areas. While these tests can suggest the presence of bone cancer, a biopsy is typically needed to confirm the diagnosis. During a biopsy, a small piece of tissue is removed from the bone and examined under a microscope to determine the presence and type of cancer.
It is important to note that bone cancer is a rare condition, and most people who develop it do not have any specific risk factors. It usually occurs without a known cause. However, certain factors can increase the risk, such as previous cancer treatment, radiation therapy, and specific genetic disorders. Additionally, benign bone conditions, such as Paget disease of the bone or multiple enchondromas, can rarely progress to cancer.
Healthcare providers may sometimes discover bone cancer while investigating a fracture, as bone cancers can weaken the bones they form in, leading to pathologic fractures. Therefore, it is crucial to pay attention to any unusual changes in your bones, such as lumps, increasing bone pain, or persistent pain that gets worse at night. If you notice any of these symptoms, it is important to consult a healthcare provider for further evaluation and diagnosis.

Bone cancer symptoms: pain, swelling, and weight loss
Bone cancer refers to several types of rare, malignant tumors that start in your bones. The most common symptom of bone cancer is bone pain or tenderness, which usually gets worse at night and may feel like throbbing, aching, or stabbing. The pain gradually becomes more persistent and may be accompanied by unexplained swelling around the affected area, making it difficult to move, especially if the swelling is near a joint.
In some cases, a lump may be felt in the affected area, which can be hard or soft to the touch. These lumps are often painless, and providers may mistake them for other conditions, such as growing pains, sports injuries, arthritis, or Lyme disease. Bone cancer can also cause pathologic fractures, where the tumor weakens the bone, leading to a break.
Imaging tests, such as X-rays, MRI scans, CT scans, and PET scans, are commonly used to detect bone cancer and determine its extent. These tests help doctors visualize the inside of the body and identify any abnormalities. However, a biopsy, which involves taking a tissue or cell sample, is usually needed to confirm the diagnosis.
It is important to distinguish primary bone cancers, which originate in the bones, from cancers that have spread to the bones from other parts of the body (bone metastasis). Breast, prostate, and lung tumors are the cancers most likely to metastasize (spread) to the bones. Accurate diagnosis and treatment of bone cancer depend on identifying the specific type of cancer and the affected bone and body parts.

Bone cancer treatment: cure and management options
Bone cancer is a rare form of cancer that includes several types of malignant tumours that start in the bones. It is usually treated with surgery and chemotherapy, but radiotherapy and targeted medicines are also sometimes used.
The first step in diagnosing bone cancer is usually an X-ray, which can show abnormal areas of bone. If an abnormal area is spotted, a biopsy is usually needed to confirm it is bone cancer. A bone biopsy involves removing a small piece of tissue from the bone so that a specialist can examine it under a microscope. Other imaging tests may also be used, such as MRI scans, CT scans, and bone scans, which can show if the cancer has spread to other bones.
Once bone cancer has been diagnosed, a treatment plan will be developed according to the patient's needs. Surgery is the main treatment for most bone cancers, with the goal being to remove as much of the cancer as possible. If the cancer is in an arm or leg, limb-sparing surgery is often possible, which removes the cancer cells but allows the patient to keep full use of their arm or leg. If bone is removed, it may be replaced with a bone graft or an internal device called an endoprosthesis.
Chemotherapy may also be recommended, either before or after surgery, to shrink the tumour and destroy remaining cancer cells. It is often used for osteosarcoma and Ewing's sarcoma. Radiotherapy is not always used to treat bone cancer, as it is not highly sensitive to radiation. However, it may be given if the tumour cannot be operated on or if cancer cells remain after surgery. New radiation therapy techniques allow doctors to target tumours more precisely, delivering the maximum amount of radiation with minimal damage to healthy cells.
