Lung cancer is very hard to treat and has usually already spread by the time it's discovered. This is because people who have symptoms usually hold off on seeing a doctor, thinking it is something else, or that it will go away. Early detection is extremely important in fighting this disease. Seeing a doctor right away with any signs like chronic cough, coughing up blood or any other concerns is paramount.
Early signs of lung cancer is when someone is having trouble breathing. When they have short breath and cough constantly. For early detection, it's very helpful to get checked by a doctor fast.
