Lung
Lung cancer is the leading cause of cancer deaths in both women and men in the United States and throughout the world. It is causing up to 3 million deaths annually around the world. Only one in ten patients diagnosed with this disease will survive the following five years.
A person with lung cancer may have the following kinds of symptoms:
• No symptoms - in up to 25% of people who have lung cancer, the cancer is first discovered on a routine chest x-ray or CT scan as a solitary small mass somewhere in the lung. These patients with small single masses often report no symptoms of lung cancer at the time it is discovered.
• Symptoms related to the cancer - a cough that doesn’t go away and gets worse over time, constant chest pain, shortness of breath, hemoptysis (bloody, coughed-up sputum).
• Nonspecific symptoms - loss of appetite, weight loss, fatigue.
• Symptoms related to metastasis - lung cancer that has spread to the bones may produce excruciating pain at the sites of bone involvement. Cancer that has spread to the brain may cause a number of neurological symptoms that may include blurred vision, headaches, seizures, or symptoms of stroke such as weakness or loss of sensation in parts of the body.
Anyway, I strongly recommend to see a doctor if you experience: a new persistent cough or worsening of an existing chronic cough, blood in your sputum, persistent bronchitis or repeated respiratory infections, chest pain, unexplained weight loss and/or fatigue. Probably your doctor will recommend you some tests.
