Cancer - brain

More than 17,000 people in the United States receive a brain tumor diagnosis. Some tumors are benign (noncancerous). Noncancerous tumors can usually be removed and are not likely to recur. Other tumors are malignant (cancerous). These tumors interfere with vital functions and are life threatening. Cancerous brain tumors usually grow rapidly,...

    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.
