Lung cancer - Animation

Cancer can affect just about any part of the body, from the colon to the pancreas. Some cancers grow quickly, while others grow more slowly and are easier to treat. But of all the different cancers out there, one of the deadliest is lung cancer. Let's talk today about lung cancer. Cancer starts when cells begin to grow uncontrollably and form tumors. In the case of lung cancer, the tumors start in the lungs. Sometimes cancer starts somewhere else in the body and then spreads to the lungs. In that case, it's called metastatic cancer to the lung. "Metastatic" means disease that has spread. There are two types of lung cancer. The most common, and slower-growing form is non-small cell lung cancer. The other, faster-growing form is called small cell lung cancer. The most common way to get lung cancer is to smoke cigarettes. The more cigarettes you smoke and the earlier you start smoking, the greater your risk is. Even being around someone who smokes and breathing in the secondhand smoke from their cigarettes increases your risk of getting lung cancer. Even though smoking makes you much more likely to get lung cancer, you don't have to smoke or be exposed to smoke to get the disease. Some people who have lung cancer never lit up a cigarette in their life. They have been exposed to cancer-causing substances like asbestos, diesel fumes, arsenic, radiation, or radon gas. Or, they may not have had any known lung cancer risks. The most common signs of lung cancer are a cough that won't go away, chest pain, shortness of breath, weight loss, and fatigue. But just because you have these symptoms it doesn't mean that you have don't have lung cancer. These can also be signs of other conditions, like asthma or a respiratory infection. If you do have these symptoms, see your doctor. A chest x-ray, MRI, or CT scan can view the inside of your lungs to look for signs of cancer or other diseases. What happens if you do have lung cancer?Doctors divide lung cancer into stages. The higher the stage, the more the cancer has spread. For example, a stage 1 cancer is small and hasn't spread outside of the lungs. A stage 4 cancer has spread to the other organs, such as the kidneys or brain. Depending upon the type and stage of your lung cancer, you may need surgery to remove part or all of your lung. Or, your doctor may recommend radiation or chemotherapy to kill cancer cells. If you have lung cancer, how well you do depends upon the stage of your disease and the type of lung cancer that you have. Early-stage cancers have the highest survival and cure rates. Late-stage cancers are harder to treat. Because lung cancer can be so deadly, prevention is key. The most important that thing you can do is to stop smoking, and avoid being around anyone who does smoke.

Chronic obstructive pulmonary disease - Animation

For years, you've enjoyed relaxing with a cigarette in your hand, and looked forward to your cigarette breaks at work, but now, all of that smoking has caught up with you. You're coughing, wheezing, often out of breath. Could you have chronic obstructive pulmonary disease? Let's talk about chronic obstructive pulmonary disease, or COPD, for short. COPD is a lung disease that's usually caused by smoking, although some people who smoke for years never get the condition, while a few get COPD even if they've never lit up. Most people with COPD have a combination of a cough that just won't go away, called chronic bronchitis, and lung damage, called emphysema. The symptoms of COPD can sneak up on you slowly. Over time, you'll develop a cough that lingers, day after day. You'll feel tired, and have trouble catching your breath. Only your doctor can tell for sure whether this is COPD. To test for it, you'll need to breathe or blow into a machine as hard as you can, and hold that breath, as long as you can, in a test called spirometry. You may also need to have a blood test to determine how much oxygen and carbon dioxide is in your blood. If you have COPD, the ways things stand now, you'll have it for life, as there is no cure for this disease. However, there are ways to control the condition and help you breathe more easily. The first thing you do, absolutely need to do, is stop smoking, which will help slow down the damage to your lungs. A few medicines can help relieve COPD symptoms. You may breathe in a bronchodilator medicine through an inhaler to open up your airways, or take steroids to bring down the swelling in your lungs. If you're having real trouble breathing though, call your local emergency services number. You may need to visit the hospital for oxygen or breathing assistance. You may also need to take antibiotics during flare-ups, because getting an infection can make your COPD worse. Though it may be hard to exercise when you're feeling out of breath, staying active will help keep your muscles strong. Your doctor can teach you how to breathe in a different way so that you can exercise with COPD. You can help avoid the shortness of breath, the coughing, and the wheezing of COPD by butting out, kicking your cigarette habit as soon as possible. Not smoking is the absolute best way to prevent COPD. Ask your doctor about programs and medicines that may make it easier for you to quit.
