Lung cancer is the DEADLIEST type of cancer in the U.S. But... it's also the MOST PREVENTABLE. SMOKING is behind 87 PERCENT of lung cancer cases. If you HAVEN'T kicked your cigarette, pipe or cigar habit, please seek help to quit.The second most common cause of lung cancer is exposure to radon, which is a radioactive gas that enters houses and buildings through the soil. LONG-TERM exposure to industrial chemicals such as arsenic and asbestos can also cause lung cancer. Exposure to air pollution and secondhand smoke are also risk factors for lung cancer. A small percentage of people owe their lung cancer to their genes, while an even smaller fraction develops lung cancer for UNKNOWN reasons. There are two man forms of lung cancer: SMALL cell lung cancer, which makes up about 10 to 15 percent of cases, and NON-small cell lung cancer, which comprises 85 to 90 percent of cases. The cancers cells differ in size and shape and require different treatments.A doctor may decide that SURGERY is the best way to get rid of the tumor. Surgeons will remove the part of the lung the tumor is in. Sometimes it IS necessary to take out an entire lung. Before or after surgery, radiation and chemotherapy are frequently used. Radiation can reduce tumor size by targeting cancer tumors EXTERNALLY with high-powered beams such as X-rays, or INTERNALLY with radioactive seeds or needles placed NEAR the tumor. During chemotherapy, a lung cancer patient takes intravenous medication that is supposed to stop the reproduction and growth of cancer cells. [RR note: does chemo stop growth, but not reduce existing tumor size?]A NEWER form of treatment is called targeted drug therapy. This also kills off cancer cells, but in a new way, with LESS side effects than chemo. These drugs, such as epidermal growth factor receptor inhibitors, attack the processes that enable cancer cells to grow. Since it's quite new, targeted drug therapy is usually reserved for more advanced forms of lung cancer. Not all patients receive ALL forms of treatment. You and your doctor will make decisions based on overall health, cancer TYPE and cancer STAGE. Treatment during the last stage of cancer often involves experimental clinical trials, symptom relief and hospice care. If you're a smoker who is experiencing a worsening, relentless cough, chest pain, hoarseness, weight loss, bloody phlegm and shortness of breath, head to the doctor for a checkup. Early detection increases your chance of effective treatment.More »

For more than 18 million Americans, SLEEP APNEA causes difficulty breathing while they sleep. But most people with the condition snooze right through it - it's their sleeping partner or other family members who hear the repeated gasping, snorting and long pauses between breaths -- sometimes for as long as a minute or more-- that are the sure signs of sleep apnea. If you are a chronic, constant snorer, talk to your doctor about being evaluated for sleep apnea. NOT DRINKING, STOPPING SMOKING, AND LOSING WEIGHT CAN REVERSE the condition IN SOME CASES, but most of the time sleep apnea requires treatment to avoid the serious health problems it can trigger. These include heart disease, diabetes, depression, chronic sleep problems, high blood pressure. DIFFICULTY concentrating, IRRITABILITY, sexual problems, and learning and memory issues. For a proper diagnosis, you may have to spend the night at a sleep center so researchers can monitor your eye movement, muscle activity, heart rate, breathing, and blood oxygen levels while you're sleeping. They will also examine your throat and airways: Having a small upper airway, recessed chin, small jaw, large overbite, large neck, large tongue, large tonsils, or a large uvula, which is that dangly thing at the back of your mouth, can ALL contribute to sleep apnea. The most COMMON solution is to use a CPAP, or continuous positive airway pressure device. It's a mask that you wear over your nose and-or mouth during sleep, and it's designed to PREVENT any pauses in breathing. In SOME cases, doctors will recommend dental devices designed to reposition parts of your mouth to facilitate breathing, Upper airway surgery may also be needed.Learn more about better breathing by watching other videos in this series.More »

When's the last time you looked at your mucus color? Noticed any mucus color changes? Understanding mucus color can help you tell your health status.
Transcript: When you blow your nose or cough up some phlegm how do you know what's a healthy color and what's not?...
When you blow your nose or cough up some phlegm how do you know what's a healthy color and what's not? Well, clear thin mucus is usually the sign of a healthy system, but if there is a CONSISTENCY and COLOR change, there may be something wrong. If you have a bacterial or viral infection your mucus turns LIGHT YELLOW or GREEN because white blood cells that respond to an infection contain a green-tinged enzyme. It mixes with the mucus in your nose or the phlegm in your lungs and throat, changing the color. Because there is a good chance this colored mucus is a symptom of a viral infection, don't run to the doctor or take antibiotics. Instead, drink lots of fluids and get plenty of rest to beat the bug. If you don't feel better in a week, THEN it's time to go to your physician. If your phlegm is thick and DARK yellow, DARK green or brown, it could indicate that your infection may have traveled to your LUNGS. If your primary symptom is constant coughing, BRONCHITIS is a real possibility. Smokers who have a persistent cough may have CHRONIC bronchitis, which can be a symptom of chronic obstructive pulmonary disease - or COPD - the fourth leading cause of death in the U.S. If you suspect you have chronic bronchitis, quit smoking and visit your doctor. DARK YELLOW or dark green phlegm may indicate PNEUMONIA. If the cough is also accompanied by fever, shortness of breath, sweating, chills, headache, muscle pain, fatigue and chest pain, you should see a doctor. BLOODY phlegm is an alarming symptom. It can indicate all kinds of trouble including tuberculosis, lung cancer or a pulmonary embolism -- a blood clot your lungs. Head to your doctor or the emergency room immediately. You should also seek medical assistance if you're coughing up pink, frothy mucus-this symptom could indicate that you have pulmonary edema, or fluid in your lungs. However, regardless of your mucus color -if you're really feeling unwell, see your primary physician-sooner than later.

Two types of inhalers, long acting and rescue, can help relieve symptoms of COPD and asthma. Watch this video for help when understanding inhalers.

Asthma and COPD are commonly treated with two types of INHALED medications. Long-acting inhalers ease chronic symptoms and prevent attacks. Short-acting RESCUE inhalers stop an asthma attack or COPD exacerbation at the moment they hit. RESCUE and long-acting medicines are administered through 2 different types of inhalers. Both require a prescription.The METERED DOSE INHALER, or MDI, is the MOST common medication-delivery method. This type of inhaler has a PRESSURIZED canister that contains the medicine. A mouthpiece is attached to the canister. A specific dose of medicine is released as a mist or a spray when you push the canister into the mouthpiece. You have to time your breath as you push, so using an MDI can be a little tricky at first. Some people, especially CHILDREN and the elderly, attach a SPACER to their MDI. This makes it easier to breathe in so the dose goes into your lungs, instead of accidentally settling on the tongue and throat. DRY POWDER INHALERS contain LONG-ACTING medication. These are sometimes difficult to use because you have to inhale the dry powder FAST and HARD to breathe in the full dose. If you are inhaling steroids from either type of delivery system it is a good idea to rinse your mouth out afterwards to remove any medication from your tongue or gums.Young children, the elderly and other people who can't use inhalers use NEBULIZERS to receive their asthma or COPD medication. These devices deliver misted medication through a tube or face mask. To learn more about asthma and COPD treatment, take a look at more videos in this series.More »

The contraptions you see in your pulmonologist's exam room AREN'T there to scare you - they have a real purpose! First, let's talk about the SPIROMETER. This device helps doctors diagnose ASTHMA, chronic obstructive pulmonary disease, BRONCHITIS and emphysema. During a spirometry test, a patient exhales HARD into the device several times. The results tell a doctor MANY things about your lung function-but the two MAIN measurements show how much air you can exhale after INhaling deeply, and the amount of air you can exhale in ONE SECOND. Spirometry is useful to give an initial diagnosis of disease, to gauge the SEVERITY of disease, and to determine whether or not medications-such as bronchodilators-are working. The measure of what is called FEV1 or the forced expiratory volume in 1 second, let's you know how you are doing. If, after using a bronchodilator, you can blow out less than 30% of the expected volume of air, you have severe lung dysfunction; if you can blow out 80% or MORE then it is mild. A methacholine challenge test HELPS CONFIRM AN ASTHMA DIAGNOSIS. Before and after spirometry, you inhale increasing amounts of methacholine-a substance known to cause airway spasms. If spirometry shows it reduces your lung function by 20% or more, your diagnosis of asthma is confirmed. A bronchodilator is always provided afterwards to stop the reaction. A NITRIC OXIDE TEST also helps a doctor diagnose asthma, as well as COPD and chronic bronchitis. When there is airway inflammation, a person exhales nitric oxides. The amount exhaled indicates the extent of inflammation A lung DIFFUSION test evaluates how well the lungs can SEND oxygen to the blood and DIFFUSE carbon dioxide out of it. This test HELPS diagnose COPD, emphysema, pulmonary hypertension and other lung conditions. COPD patients and doctors use PULSE OXIMETERS to make TREATMENT decisions. This non-invasive device is placed on your finger, toe or earlobe. It emits infrared beams of light that measure how much oxygen is in the blood. Doctors use pulse oximetry to see if oxygen therapy is working, and patients can use it at home to find out if they need to adjust their oxygen flow during exercise or sleep. An arterial blood gas test also measures the amount of oxygen AND CARBON DIOXIDE in the blood, but it's more ACCURATE than pulse oximetry. This test is done in a doctor's office because it involves drawing blood. It's used to initially decide if a patient needs oxygen therapy or later to CONFIRM the results of pulse oximetry.
