Lung cancer is a type of cancer that begins in the lungs. Your lungs are two spongy organs in your chest that take in oxygen when you inhale and release carbon dioxide when you exhale. Lung cancer is the leading cause of cancer deaths worldwide. People who smoke have the greatest risk of lung cancer, though lung cancer can also occur in people who have never smoked. The risk of lung cancer increases with the length of time and number of cigarettes you’ve smoked. If you quit smoking, even after smoking for many years, you can significantly reduce your chances of developing lung cancer. Symptoms Lung cancer typically doesn’t cause signs and symptoms in its earliest stages. Signs and symptoms of lung cancer typically occur when the disease is advanced. A new cough that doesn’t go away Coughing up blood, even a small amount Shortness of breath Chest pain Hoarseness Losing weight without trying Bone pain Headache Causes Smoking causes the majority of lung cancers both in smokers and in people exposed to secondhand smoke. But lung cancer also occurs in people who never smoked and in those who never had prolonged exposure to secondhand smoke. In these cases, there may be no clear cause of lung cancer.

Multiple myeloma is a cancer that forms in a type of white blood cell called a plasma cell. Healthy plasma cells help you fight infections by making antibodies that recognize and attack germs. In multiple myeloma, cancerous plasma cells accumulate in the bone marrow and crowd out healthy blood cells. Rather than produce helpful antibodies, the cancer cells produce abnormal proteins that can cause complications. Treatment for multiple myeloma isn’t always necessary right away. If the multiple myeloma is slow growing and isn’t causing signs and symptoms, your doctor may recommend close monitoring instead of immediate treatment. For people with multiple myeloma who require treatment, a number of options are available to help control the disease. Symptoms Signs and symptoms of multiple myeloma can vary and, early in the disease, there may be none. Bone pain, especially in your spine or chest Nausea Constipation Loss of appetite Mental fogginess or confusion Fatigue Frequent infections Weight loss Weakness or numbness in your legs Causes Doctors know that myeloma begins with one abnormal plasma cell in your bone marrow the soft, blood-producing tissue that fills in the center of most of your bones. The abnormal cell multiplies rapidly. Because cancer cells don’t mature and then die as normal cells do, they accumulate, eventually overwhelming the production of healthy cells. In the bone marrow, myeloma cells crowd out healthy blood cells, leading to fatigue and an inability to fight infections. The myeloma cells continue trying to produce antibodies, as healthy plasma cells do, but the myeloma cells produce abnormal antibodies that the body can’t use. Instead, the abnormal antibodies build up in the body and cause problems such as damage to the kidneys. Cancer cells can also cause damage to the bones that increases the risk of broken bones.
