Why do I need a DEXA scan?

A bone-density test is a way to measure the strength of your bones. The test, called a DEXA scan, is a kind of X-ray. Many people get a bone-density test every few years. The main reason to have the test is to find and treat serious bone loss, called osteoporosis, and prevent fractures and disability.
A.

How much does it cost for a DEXA scan?

A DEXA scan costs about $125. And if your doctor prescribes a drug when you only have mild bone loss, you spend money you don't need to. A month's supply of generic alendronate can cost as much as $75. Fosamax, the brand-name of the same drug, can cost twice as much.
  • What is a DEXA scan for body fat?

    DEXA means dual-energy absorptiometry. It is the gold standard for measuring body composition and bone health. A DexaFit DEXA (DXA) scan is a simple and easy 10-minute test that measures your total body fat and includes the exact breakdown of bone mass, fat tissue, and muscle in your body.
  • How long does it take to get the results of a DEXA scan?

    An X-ray detector inside the scanning arm measures the amount of X-rays that have passed through your body. This information will be used to produce an image of the scanned area. A DEXA scan usually takes around five minutes, although it depends what part of the body is being scanned.
  • What is a DEXA scan used for?

    A dual energy X-ray absorptiometry (DEXA) scan, also called a bone density scan, is a common technique used to measure bone density. This completely painless procedure is easily performed and exposes the patient to minimal radiation.
B.

Can a DEXA scan detect cancer?

DEXA scan. A DEXA scan is a test that measures bone mineral density. Short for dual-energy X-ray absorption, the DEXA scan helps your doctor evaluate bone health and determine the likelihood of osteoporosis or bone fractures. This scan also may help detect if cancer has metastasized, or spread, to the bones.
  • Where does bone cancer usually start?

    Osteosarcoma. Osteosarcoma (also called osteogenic sarcoma) is the most common primary bone cancer. It starts in the bone cells. It most often occurs in young people between the ages of 10 and 30, but about 10% of osteosarcoma cases develop in people in their 60s and 70s.
  • Can you see cancer in a CT scan?

    Doctors use a computed tomography (CT) scan, also called a CAT scan, to find cancer. They also use it to learn more about cancer after they find it. Learn the cancer's stage. Stage is a way to describe where the cancer is, if it has spread, and if it is changing how your organs work.
  • Can bone cancer be detected by a blood test?

    Complete blood count (CBC). This common blood test measures the amount of various types of blood cells in a sample of your blood. Blood cancers may be detected using this test if too many or too few of a type of blood cell or abnormal cells are found. A bone marrow biopsy may help confirm a diagnosis of a blood cancer.
C.

What is a test for body composition?

In physical fitness, body composition is used to describe the percentages of fat, bone, water and muscle in human bodies. Because muscular tissue takes up less space in our body than fat tissue, our body composition, as well as our weight, determines leanness.
  • What is the difference in body weight and body composition?

    The difference is that a standard scale performs one measurement—your total body weight. A body composition scale breaks down that total body weight into the various elements that make it up. Your body is composed of three main components: fat, lean body mass (muscle, bone, and organs), and water.
  • How can you improve your body composition?

    To change your body composition, you won't have one goal (like “lose weight” or “gain muscle”). You will have two: Reduce Fat Mass. Increase Lean Body Mass.
  • What is the best way to maintain a healthy body composition?

    Calculate your BMR and daily calorie needs. Eat a high protein diet rich in vegetables and fruits. Do strength training at least 2 days a week. Monitor your body composition once a week and adjust your diet and / or exercise efforts accordingly.
