WHAT YOU NEED TO KNOW:
Lung cancer is a type of cancer that starts in the lungs. Lung cancer is the leading cause of cancer deaths worldwide. Cigarette smoking causes most lung cancer, but it can also develop in people who do not smoke.
Call your local emergency number (911 in the US) if:
- You have severe chest pain when you take a deep breath or cough.
- You have new or worse trouble breathing.
Seek care immediately if:
- You cannot think clearly.
- You cough up blood, or more blood than before.
- Your lips or nails look blue or pale.
Call your doctor or oncologist if:
- You have a fever.
- You are vomiting and cannot keep food or liquids down.
- You have questions or concerns about your condition or care.
Lower your risk for lung cancer:
- Do not smoke, and avoid secondhand smoke. Nicotine and other chemicals in cigarettes and cigars can cause lung damage. Ask your healthcare provider for information if you currently smoke and need help to quit. E-cigarettes or smokeless tobacco still contain nicotine. Talk to your healthcare provider before you use these products.
- Have lung cancer screening, if recommended. Lung cancer screening is a test done every year to find lung cancer early. Screening is different from diagnosis because screening is used before you have any signs or symptoms. Screening is offered to adults aged 50 to 80 who have at least a 20-pack year history of smoking. Pack-years are the number of cigarette packs you smoked multiplied by the number of years you smoked. Examples are 1 pack of cigarettes each day for 20 years, or 2 packs each day for 10 years. Lung cancer screening has benefits and risks. Talk with your healthcare provider about the benefits and risks to help you decide if lung cancer screening is right for you.
- Have your home tested for radon. Do this especially if you live in an area where radon is a known problem.
- Wear protective gear if you work with substances or chemicals that can cause cancer. Avoid exposure as much as you can. Follow safety precautions.
- Eat a variety of healthy foods. Healthy foods include fruits, vegetables, whole-grain breads, low-fat dairy products, beans, lean meats, and fish.
- Be physically active throughout the day. Physical activity such as exercise can help increase your energy level and fight illness. Be physically active for at least 30 minutes per day, on most days of the week. Include aerobic activity, such as walking or riding a bicycle. Also include strength training at least 2 times each week. Your healthcare providers can help you create a physical activity plan.
Follow up with your doctor or oncologist as directed:
You will need to see your oncologist for ongoing treatment. Write down your questions so you remember to ask them during your visits.
