Bone scans show changes in your bones, but they don't tell you if it's because of cancer or not. You may have to have other tests to figure out what the changes mean. These extra tests will tell you if the spots are cancerous or related to another problem, like arthritis.
The areas where the radionuclide collects are called "hot spots," and may indicate the presence of conditions such as arthritis , malignant (cancerous) bone tumors , metastatic bone cancer (cancer which has spread from another site, such as the lungs), bone infections , bone trauma not seen on ordinary X-rays, and ...
Many changes that show up on a bone scan are not cancer. With arthritis, the radioactive material tends to show up on the bone surfaces of joints, not inside the bone. But it can be hard to tell the difference between arthritis and cancer — especially in the spine.
A bone scan can also be an important tool for detecting cancer that has spread (metastasized) to the bone from the tumor's original location, such as the breast or prostate.
Bone Scan is a study used to detect any inflammatory process in the body. When the source of pain is not clear the bone scan is able to direct the attention of your physician to the area inflammation. The inflammation may be caused by fracture, infection, tumor, or high bone turn over.
Overview. Bone cancer can begin in any bone in the body, but it most commonly affects the pelvis or the long bones in the arms and legs. Bone cancer is rare, making up less than 1 percent of all cancers. In fact, noncancerous bone tumors are much more common than cancerous ones.
Bone pain is often the first symptom of cancer that has spread to the bone. The pain may come and go at first. It tends to be worse at night and may get better with movement. Later on, it can become constant and may be worse during activity.
Trouble is, bone cancer symptoms can mimic those of other, more common conditions, including arthritis, fractures and other acute skeletal injuries, and benign bone tumors.
Blood tests. Blood tests are not needed to diagnose bone cancer, 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 cancer may be more advanced.
MRI is the most effective way to diagnose problems within any joint and the image sensitivity makes it the most accurate imaging tool available in detecting arthritis and other inflammatory changes. MRI is also a key diagnostic tool when patients have lower back pain, radiating pain or hip/groin pain.
2. How is arthritis diagnosed? Doctors usually diagnose arthritis using the patient's medical history, physical examination, X-rays, and blood tests. It is possible to have more than one form of arthritis at the same time.
Scans may be done to check for joint inflammation and damage. These can help tell the difference between types of arthritis and can be used to monitor how your condition is progressing over time. Scans that may be done to diagnose and monitor rheumatoid arthritis include: X-rays.
Bone pain can cause a dull or deep ache in a bone or bone region (e.g., back, pelvis, legs, ribs, arms). Bone pain feels different than muscle or joint pain.
Pain in the area of the tumor is the most common sign of bone cancer. At first, the pain might not be there all the time. It may get worse at night or when the bone is used, such as when walking for a tumor in a leg bone. Over time, the pain can become more constant, and it might get worse with activity.
For example, bone cancer is most frequently diagnosed in children and adolescents (people under age 20), with about one-fourth of cases occurring in this age group.
Rarely, people with a bone sarcoma may have symptoms such as fever, generally feeling unwell, weight loss, and anemia, which is a low level of red blood cells.
Unfortunately, instances of bone cancer misdiagnosis are still common, which is the most likely reason for survival rates remaining unchanged for the past 25 years.
A bone scan is a test that can help doctors diagnose problems with your bones. It is a useful tool for finding cancer that has started in or spread to the bone. It can also help your doctor check how well treatment is working for cancer in the bone.
A bone density test may be ordered if your doctor suspects either osteopenia or osteoporosis. Some rheumatologists may also request this test be done if you have RA or PsA. The purpose is to help determine whether you need to be treated for bone loss before it leads to fractures.
Because MRIs can reveal abnormal appearance or physical abscess in bones, they are more effective at detecting bone cancer than traditional bone scans. They can also identify cancer earlier than bone scans can, allowing MRIs to detect the disease before cancer reaches the bones.
Areas of fast bone growth or repair absorb more tracer and show up as bright or "hot" spots in the pictures. Hot spots may point to problems such as arthritis, a tumor, a fracture, or an infection.
