AMBULATORY CARE:
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.
Types of lung cancer:
The main differences between the 2 major types is the cells the cancer starts in and how it grows:
- Non-small cell lung cancer (NSCLC) is the most common type of lung cancer. Adenocarcinoma, squamous cell carcinoma, and large cell carcinoma are the examples of NSCLC.
- Small cell lung cancer (SCLC) is less common and is sometimes called oat cell cancer. These types of cells are small and round and can be more aggressive than NSCLC.
Common signs and symptoms:
- Chest pain
- Shortness of breath or wheezing
- A cough that will not go away, and gets worse over time
- Coughing up blood
- Hoarseness
- Loss of appetite or weight loss without trying
- Headache
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.
Treatment for lung cancer
may include the following:
- Surgery may be needed to remove the lung cancer. Part of your lymph nodes may be removed to check for signs of cancer. Surgery may also be needed if the cancer cannot be removed completely. In this case surgery may help treat complications or decrease your symptoms.
- Radiation therapy uses beams of intense energy, such as x-rays, to shrink or kill cancer cells.
- Chemotherapy medicines are used to kill cancer cells. Chemo may be given as a pill or in an IV. Chemo can be used by itself, before with or after surgery, and with radiation.
- Targeted medicine therapy focuses on specific targets inside cancer cells.
- Immunotherapy stimulates your immune system to fight the cancer. Cancer cells produce substances that help them hide from your immune system. Immunotherapy can block these substances and help your body identify the cancer cells so they can be destroyed.
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. Screening is a test done to find lung cancer early. Screening may be recommended if you are a heavy smoker or you quit within the past 15 years. A heavy smoker means at least 1 pack each day for 20 years or 2 packs each day for 10 years. You can have screening if you are at least 50 years old, never had lung cancer, and do not have any symptoms. Screening may be done 1 time each year until you are 77 to 80. Ask your provider for more information about lung cancer screening.
- 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.
