Who is at risk for Lung Cancer? ? 

Another substance that can contribute to lung cancer is asbestos. Asbestos is used in shipbuilding, asbestos mining and manufacturing, insulation work, and brake repair, but many products that contain asbestos have been phased out over the past several decades. If inhaled, asbestos particles can lodge in the lungs, damaging cells and increasing the risk for lung cancer.
What are the symptoms of Lung Cancer ? 

The possible signs of lung cancer are: - a cough that doesn't go away and gets worse over time  - constant chest pain  - coughing up blood  - shortness of breath, wheezing, or hoarseness  - repeated problems with pneumonia or bronchitis  - swelling of the neck and face  - loss of appetite or weight loss  - fatigue. a cough that doesn't go away and gets worse over time constant chest pain coughing up blood shortness of breath, wheezing, or hoarseness repeated problems with pneumonia or bronchitis swelling of the neck and face loss of appetite or weight loss fatigue.
What is (are) Lung Cancer ? 

A person who has had lung cancer once is more likely to develop a second lung cancer compared to a person who has never had lung cancer. Second cancers arise in a different site than the original cancer. If the original cancer returns after treatment, it is considered recurrent, not a second cancer. Quitting smoking after lung cancer is diagnosed may prevent the development of a second lung cancer.
How to diagnose Lung Cancer ? 

Doctors can perform several tests to stage lung cancer. Staging means finding out how far the cancer has progressed. The following tests are used to stage lung cancer: - Computerized tomography or CAT scan is a computer linked to an x-ray machine that creates a series of detailed pictures of areas inside the body. Computerized tomography or CAT scan is a computer linked to an x-ray machine that creates a series of detailed pictures of areas inside the body. - Magnetic resonance imaging, or MRI, is a powerful magnet linked to a computer that makes detailed pictures of areas inside the body.  - Radionuclide scanning uses a mildly radioactive substance to show whether cancer has spread to other organs, such as the liver.

Radionuclide scanning uses a mildly radioactive substance to show whether cancer has spread to other organs, such as the liver. - A bone scan uses a small amount of a radioactive substance to show whether cancer has spread to the bones.  - A mediastinoscopy or mediastinotomy can help show whether the cancer has spread to the lymph nodes in the chest by removing a tissue sample. The patient receives a general anesthetic for this procedure. A bone scan uses a small amount of a radioactive substance to show whether cancer has spread to the bones.

What are the treatments for Lung Cancer ? 

Doctors treat patients with non-small cell lung cancer in several ways, and surgery is a common treatment. Cryosurgery, a treatment that freezes and destroys cancer tissue, may be used to control symptoms in the later stages of non-small cell lung cancer. Doctors may also use radiation therapy and chemotherapy to slow the progress of the disease and to manage symptoms. See more on treatments for non-small cell lung cancer.
What are the treatments for Lung Cancer ? 

Small cell lung cancer spreads quickly. In many cases, cancer cells have already spread to other parts of the body when the disease is diagnosed, so chemotherapy is usually the best choice. See more on treatments for small cell lung cancer.
What are the treatments for Lung Cancer ? 

Researchers continue to look at new ways to combine, schedule, and sequence the use of chemotherapy, surgery, and radiation to treat lung cancer. Targeted therapy, using drugs that go directly to a gene mutation and repair or block the mutation from causing cancer, are the current gold standard for treating some types of lung cancer. Get more information on current lung cancer research.
What are the treatments for Lung Cancer ? 

Researchers are working to develop drugs called "molecularly targeted agents" which kill cancer cells by targeting key molecules involved in cancer cell growth.
What is (are) Age-related Macular Degeneration ? 

Age-related macular degeneration, also known as AMD, is an eye disease that affects the macula, a part of the retina. The retina sends light from the eye to the brain, and the macula allows you to see fine detail. AMD Blurs Central Vision AMD blurs the sharp central vision you need for straight-ahead activities such as reading, sewing, and driving. AMD causes no pain. How AMD Progresses In some cases, AMD advances so slowly that people notice little change in their vision. In others, the disease progresses faster and may lead to a loss of vision in both eyes. AMD is a common eye condition among people age 50 and older. It is a leading cause of vision loss in older adults. Two Forms of AMD There are two forms of age-related macular degeneration -- dry and wet.
Who is at risk for Age-related Macular Degeneration? ? 

Risk Increases With Age AMD is most common in older people, but it can occur during middle age. The risk increases with age. Other Risk Factors Other risk factors include - Smoking  - Obesity  - Race. Whites are much more likely to lose vision from AMD than African-Americans.  - Family history. People with a family history of AMD are at higher risk of getting the disease.  - Gender. Women appear to be at greater risk than men. Smoking Obesity Race.

What are the symptoms of Age-related Macular Degeneration ? 

AMD is detected during a comprehensive eye exam that includes a visual acuity test, a dilated eye exam, and tonometry. Tests for AMD - The visual acuity test is an eye chart test that measures how well you see at various distances.  - In the dilated eye exam, drops are placed in your eyes to widen, or dilate, the pupils. Then, your eye care professional uses a special magnifying lens to examine your retina and optic nerve for signs of AMD and other eye problems. After the exam, your close-up vision may remain blurred for several hours.  - With tonometry, an instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test. The visual acuity test is an eye chart test that measures how well you see at various distances.

After the exam, your close-up vision may remain blurred for several hours. With tonometry, an instrument measures the pressure inside the eye. Numbing drops may be applied to your eye for this test. Your eye care professional also may do other tests to learn more about the structure and health of your eye. The Amsler Grid During an eye exam, you may be asked to look at an Amsler grid, shown here. You will cover one eye and stare at a black dot in the center of the grid. While staring at the dot, you may notice that the straight lines in the pattern appear wavy. You may notice that some of the lines are missing. These may be signs of AMD. Because dry AMD can turn into wet AMD at any time, you should get an Amsler grid from your eye care professional. You could then use the grid every day to evaluate your vision for signs of wet AMD. The Fluorescein Angiogram Test If your eye care professional believes you need treatment for wet AMD, he or she may suggest a fluorescein angiogram. In this test, a special dye is injected into your arm. Pictures are taken as the dye passes through the blood vessels in your eye. The test allows your eye care professional to identify any leaking blood vessels and recommend treatment.

Age-related macular degeneration, or AMD, is a disease that blurs the sharp, central vision you need for straight-ahead activities such as reading, sewing, and driving. AMD affects the macula, the part of the eye that allows you to see fine detail. AMD causes no pain.
What is (are) Age-related Macular Degeneration ? 

Wet AMD occurs when abnormal blood vessels behind the retina start to grow under the macula. With wet AMD, loss of central vision can occur quickly. Wet AMD is considered to be advanced AMD and is more severe than the dry form.
What is (are) Age-related Macular Degeneration ? 

Dry AMD occurs when the light-sensitive cells in the macula slowly break down, gradually blurring central vision in the affected eye. As dry AMD gets worse, you may see a blurred spot in the center of your vision. Over time, as less of the macula functions, central vision in the affected eye can be lost. If you have vision loss from dry AMD in one eye only, you may not notice any changes in your overall vision. With the other eye seeing clearly, you can still drive, read, and see fine details. You may notice changes in your vision only if AMD affects both eyes. If you experience blurry vision, see an eye care professional for a comprehensive dilated eye exam.
What is (are) Age-related Macular Degeneration ? 

Dry AMD has three stages -- early AMD, intermediate AMD, and advanced dry AMD. All of these may occur in one or both eyes. People with early dry AMD have either several small drusen or a few medium-sized drusen. Drusen are yellow deposits under the retina which often are found in people over age 50. People with early AMD have no symptoms and no vision loss. People with intermediate dry AMD have either many medium-sized drusen or one or more large drusen. Some people see a blurred spot in the center of their vision. More light may be needed for reading and other tasks. In addition to drusen, people with advanced dry AMD have a breakdown of light-sensitive cells and supporting tissue in the macula. This breakdown can cause a blurred spot in the center of your vision. Over time, the blurred spot may get bigger and darker, taking more of your central vision. You may have difficulty reading or recognizing faces until they are very close to you.

Drusen are yellow deposits under the retina. They often are found in people over age 50. Your eye care professional can detect drusen during a comprehensive dilated eye exam.
What causes Age-related Macular Degeneration ? 

Drusen alone do not usually cause vision loss. In fact, scientists are unclear about the connection between drusen and AMD. They do know that an increase in the size or number of drusen raises a person's risk of developing either advanced dry AMD or wet AMD. These changes can cause serious vision loss.
What are the symptoms of Age-related Macular Degeneration ? 

An early symptom of wet AMD is that straight lines appear wavy. If you notice this condition or other changes to your vision, contact your eye care professional at once. You need a comprehensive dilated eye exam.
What are the symptoms of Age-related Macular Degeneration ? 

The most common symptom of dry AMD is slightly blurred vision. You may have difficulty recognizing faces. You may need more light for reading and other tasks. Dry AMD generally affects both eyes, but vision can be lost in one eye while the other eye seems unaffected. One of the most common early signs of dry AMD is drusen. Drusen are yellow deposits under the retina. They often are found in people over age 50. Your eye care professional can detect drusen during a comprehensive dilated eye exam.
Who is at risk for Age-related Macular Degeneration? ? 

AMD is most common in older people, but it can occur during middle age. The risk increases with age. Other risk factors include smoking, obesity, white race, family history of AMD, and female gender.
What are the treatments for Age-related Macular Degeneration ? 

Once dry AMD reaches the advanced stage, no form of treatment can prevent vision loss. However, treatment can delay and possibly prevent intermediate AMD from progressing to the advanced stage, in which vision loss occurs.
What is (are) Age-related Macular Degeneration ? 

The AREDS formulation is a combination of antioxidants and zinc that is named for a study conducted by The National Eye Institute called the Age-Related Eye Disease Study, or AREDS. This study found that taking a specific high-dose formulation of antioxidants and zinc significantly reduced the risk of advanced AMD and its associated vision loss. Slowing AMD's progression from the intermediate stage to the advanced stage will save many people's vision.
What is (are) Age-related Macular Degeneration ? 

The daily amounts used by the study researchers were 500 milligrams of vitamin C, 400 International Units of vitamin E, 15 milligrams of beta-carotene, 80 milligrams of zinc as zinc oxide, and 2 milligrams of copper as cupric oxide. Copper was added to the AREDS formulation containing zinc to prevent copper deficiency anemia, a condition associated with high levels of zinc intake.
How to prevent Age-related Macular Degeneration ? 

There is no reason for those diagnosed with early stage AMD to take the AREDS formulation. The study did not find that the formulation helped those with early stage AMD. If you have early stage AMD, a comprehensive dilated eye exam every year can help determine if the disease is progressing. If early stage AMD progresses to the intermediate stage, discuss taking the formulation with your doctor.
What are the treatments for Age-related Macular Degeneration ? 

Wet AMD can be treated with laser surgery, photodynamic therapy, and drugs that are injected into the eye. None of these treatments is a cure for wet AMD. The disease and loss of vision may progress despite treatment.
what research (or clinical trials) is being done for Age-related Macular Degeneration ? 

The National Eye Institute scientists are - studying the possibility of transplanting healthy cells into a diseased retina   - evaluating families with a history of AMD to understand genetic and hereditary factors that may cause the disease  - looking at certain anti-inflammatory treatments for the wet form of AMD. studying the possibility of transplanting healthy cells into a diseased retina evaluating families with a history of AMD to understand genetic and hereditary factors that may cause the disease looking at certain anti-inflammatory treatments for the wet form of AMD. This research should provide better ways to detect, treat, and prevent vision loss in people with AMD.

What is (are) Osteoarthritis ? 

Affects Many Older People Osteoarthritis is the most common form of arthritis among older people, and it is one of the most frequent causes of physical disability among older adults. The disease affects both men and women. Before age 45, osteoarthritis is more common in men than in women. After age 45, osteoarthritis is more common in women. It is estimated that 33.6% (12.4 million) of individuals age 65 and older are affected by the disease. Osteoarthritis occurs when cartilage, the tissue that cushions the ends of the bones within the joints, breaks down and wears away. In some cases, all of the cartilage may wear away, leaving bones that rub up against each other. Joint Stiffness and Pain Symptoms range from stiffness and mild pain that comes and goes to severe joint pain. Osteoarthritis affects hands, low back, neck, and weight-bearing joints such as knees, hips, and feet. osteoarthritis affects just joints, not internal organs. Hands Osteoarthritis of the hands seems to run in families. If your mother or grandmother has or had osteoarthritis in their hands, youre at greater-than-average risk of having it too. Women are more likely than men to have osteoarthritis in the hands. For most women, it develops after menopause. When osteoarthritis involves the hands, small, bony knobs may appear on the end joints (those closest to the nails) of the fingers. They are called Heberdens (HEBerr-denz) nodes. Similar knobs, called Bouchards (boo-SHARDZ) nodes, can appear on the middle joints of the fingers. Fingers can become enlarged and gnarled, and they may ache or be stiff and numb. The base of the thumb joint also is commonly affected by osteoarthritis. Knees The knees are among the joints most commonly affected by osteoarthritis. Symptoms of knee osteoarthritis include stiffness, swelling, and pain, which make it hard to walk, climb, and get in and out of chairs and bathtubs. Osteoarthritis in the knees can lead to disability. Hips The hips are also common sites of osteoarthritis. As with knee osteoarthritis, symptoms of hip osteoarthritis include pain and stiffness of the joint itself. But sometimes pain is felt in the groin, inner thigh, buttocks, or even the knees. Osteoarthritis of the hip may limit moving and bending, making daily activities such as dressing and putting on shoes a challenge. Spine Osteoarthritis of the spine may show up as stiffness and pain in the neck or lower back. In some cases, arthritis-related changes in the spine can cause pressure on the nerves where they exit the spinal column, resulting in weakness, tingling, or numbness of the arms and legs. In severe cases, this can even affect bladder and bowel function.
What causes Osteoarthritis ? 

Risk Increases With Age Researchers suspect that osteoarthritis is caused by a combination of factors in the body and the environment. The chance of developing osteoarthritis increases with age. It is estimated that 33.6% (12.4 million) of individuals age 65 and older are affected by the disease. Wear and Tear on Joints Affects Cartilage Osteoarthritis often results from years of wear and tear on joints. This wear and tear mostly affects the cartilage, the tissue that cushions the ends of bones within the joint. Osteoarthritis occurs when the cartilage begins to fray, wear away, and decay. Putting too much stress on a joint that has been previously injured, improper alignment of joints, and excess weight all may contribute to the development of osteoarthritis.

Osteoarthritis is the most common form of arthritis among older people. It affects hands, low back, neck, and weight-bearing joints such as knees, hips, and feet. Osteoarthritis occurs when cartilage, the tissue that cushions the ends of the bones within the joints, breaks down and wears away. This causes bones to rub together, causing pain, swelling, and loss of motion of the joint.
How many people are affected by Osteoarthritis ? 

The chance of developing osteoarthritis increases with age. It is estimated that 33.6% (12.4 million) of individuals age 65 and older are affected by the disease.
What causes Osteoarthritis ? 

Osteoarthritis often results from years of wear and tear on joints. This wear and tear mostly affects the cartilage, the tissue that cushions the ends of bones within the joint. Osteoarthritis occurs when the cartilage begins to fray, wear away, and decay. Putting too much stress on a joint that has been repeatedly injured may lead to the development of osteoarthritis, too. A person who is overweight is more likely to develop osteoarthritis because of too much stress on the joints. Also, improper joint alignment may lead to the development of osteoarthritis.
What are the symptoms of Osteoarthritis ? 

Warning signs of osteoarthritis include -  joint pain  -  swelling or tenderness in one or more joints  -  stiffness after getting out of bed or sitting for a long time  -  a crunching feeling or sound of bone rubbing on bone.  joint pain swelling or tenderness in one or more joints stiffness after getting out of bed or sitting for a long time a crunching feeling or sound of bone rubbing on bone. Not everyone with osteoarthritis develops symptoms. In fact, only a third of people with x-ray evidence of osteoarthritis report pain or other symptoms.
How to diagnose Osteoarthritis ? 

No single test can diagnose osteoarthritis. When a person feels pain in his or her joints, it may or may not be osteoarthritis. The doctor will use a combination of tests to try to determine if osteoarthritis is causing the symptoms. These may include a medical history, a physical examination, x-rays, and laboratory tests. A patient's attitudes, daily activities, and levels of anxiety or depression have a lot to do with how much the symptoms of osteoarthritis affect day-to-day living.
What are the treatments for Osteoarthritis ? 

Warm towels, hot packs, or a warm bath or shower can provide temporary pain relief. Medications such as non-steroidal anti-inflammatory drugs, or NSAIDs, help reduce pain and inflammation that result from osteoarthritis. A doctor or physical therapist can recommend if heat or cold is the best treatment. For osteoarthritis in the knee, wearing insoles or cushioned shoes may reduce joint stress.
