Lung
Lung cancer is the most common cause of cancer-related death in men and the second most common in women. The disease kills 1.3 million people worldwide every year. Smoking is the primary cause, so it should go without saying that giving up cigarettes goes a long way to preventing the disease. If you must (and you really, really shouldn’t) smoke tobacco, then be aware of the following symptoms: shortness of breath, coughing up blood, wheezing, chest pain, weight loss, fatigue, pain when swallowing and loss of appetite.
