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.
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.
- Medicare may cover a bone density test more often than once every two years if your doctor believes it is medically necessary and you meet the above eligibility criteria. You may be eligible to receive the bone density test at no cost to you under Part B if your health-care provider accepts Medicare assignment.
- Here are 10 natural ways to build healthy bones.
- Eat Lots of Vegetables.
- Perform Strength Training and Weight-Bearing Exercises.
- Consume Enough Protein.
- Eat High-Calcium Foods Throughout the Day.
- Get Plenty of Vitamin D and Vitamin K.
- Avoid Very Low-Calorie Diets.
- Consider Taking a Collagen Supplement.
- A bone density scan requires little preparation. You may eat normally and take medications as prescribed by your doctor the morning of your test. The only restrictions are: Do not take any vitamin pills or mineral supplements the morning of your exam.
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.
- Things that make osteoporosis more likely include:
- Age. Your bone density peaks around age 30.
- Gender. Women over the age of 50 are the most likely people to develop osteoporosis.
- Family history.
- Bone structure and body weight.
- Broken bones.
- Certain diseases.
- Some medications.

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.
- Body composition is the proportion of fat and fat-free mass in your body. A healthy body composition is one that includes a lower percentage of body fat and a higher percentage of fat-free mass, which includes muscle, bones, and organs. Body composition is measured to assess your health and fitness level.
- 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.
- Hydrostatic (underwater) weighing is one of the most common means for estimating body composition in research settings and is often used as the criterion method for assessing %BF. A criterion method provides the standard against which other methodologies are compared.
