What are some preliminary signs of lung cancer?
Tightness in chest; hard to breath; constant sore throat; constant wheezing; lossing your voice off and on; pain just below shoulder blades and sometimes the rib cage (caused from excessive coughing or possibly cancer spreading from the lungs) coughing up mucus with traces of blood and it can also show up in the urine and feces. Some people with lung cancer may not have all these symptoms.
