Lung cancer occurs when abnormal cells grow in your lung tissue. It is the leading cause of cancer deaths in the United States. Kentucky has the highest rates of new lung cancer cases in the nation. Lung cancer is mostly diagnosed in people age 70 and older. Symptoms include shortness of breath and fatigue. Lung cancer screening, especially if you are at high risk, can discover lung cancers early and lead to more successful cancer outcomes. Treatment for lung cancer includes chemotherapy, radiation and surgery.
There are two types of lung cancer:
Small cell lung cancer (SCLC) grows quickly and is difficult to treat. It often starts as a relatively small tumor that spreads to other parts of the body. Specific types of SCLC include small cell carcinoma (kar-seh-NO-mah) and combined small cell carcinoma.
Non-small cell lung cancer (NSCLC) grows more slowly than SCLC. It is also more common than small cell lung cancer. About 80% of lung cancer cases are NSCLC. Specific but less common types of this cancer include adenosquamous (ah-DEE-no-skway-muss) carcinoma and sarcomatoid (sar-koh-MA-toyd) carcinoma.
Other kinds of lung cancer can start in the tissue around the lungs but aren’t called lung cancer. Lymphomas are cancers that begin in the lymph nodes. Sarcomas start in the bone or soft tissue. Pleural mesothelioma (MESS-oh-thee-lee-oh-ma) affects the lining of the lungs.
Lung cancer can grow in the body for many years without any symptoms in the early stages. If symptoms are present, they often feel similar to other less-serious illnesses. More obvious symptoms develop in the later stages of lung cancer. It is important to have regular lung cancer screening if you are at a high risk or have a family history of lung cancer.
Symptoms can include:
Some conditions have similar symptoms of lung cancer. A cough or pneumonia that keeps coming back after treatment sometimes can be an early sign of lung cancer.
See a doctor if you have a cough that won’t go away, have unusual shortness of breath, are coughing up blood or have extreme fatigue. Also see a doctor if you have any combination of symptoms that concern you.
If you are at higher risk for lung cancer, you should be screened regularly by a health care provider.
Smoking is the best-known and best-studied cause of lung cancer. Cigarette smoking causes 80% to 90% of lung cancer deaths in the United States. The more cigarettes you smoke, the higher your risk for developing lung cancer. Even if you don’t smoke, if you are around someone who smokes, you are at higher risk for lung cancer from secondhand smoke. Adults who do not smoke but who are exposed to secondhand smoke have a 20% to 30% increased risk of developing lung cancer. Sometimes there is no known trigger for lung cancer.
Researchers believe that smoking damages the cells of the lungs. Cigarettes have chemicals in them that are known to cause cancer (called carcinogens). Your body can repair some of this damage, but continued exposure to smoking causes too much damage for the body to repair. The damaged cells may begin growing out of control.
Depending on your specific situation, your health care provider may want to screen you before you have symptoms. If you have a higher risk for lung cancer, or a family history of the disease, early yearly screenings may be recommended. Talk with your doctor to see which lung cancer testing might be right for you.
Norton Cancer Institute has a variety of lung cancer biopsy methods. Your doctor will talk to you about which might be the best for you.
A lung cancer biopsy can be done in a number of ways, including during a bronchoscopy (bron-KAHS-cah-pee), in which your doctor examines abnormal areas of your lungs using a tiny camera that’s passed down your throat and into your lungs. Biopsy samples also may be taken from lymph nodes or other areas where cancer has spread (metastasized), such as your liver.
Mediastinoscopy (mee-dee-ah-STIN-ahs-kah-pee) is a procedure to biopsy the lymph nodes. A surgeon makes a small cut (incision) at the base of your neck. Very thin surgical tools are inserted behind your breastbone to take tissue samples from lymph nodes.
In a needle biopsy, your doctor uses X-ray or CT images to guide a very thin needle through your chest wall and into the lung tissue to collect cells.
Many factors are important to consider when you think about treatments for lung cancer, including your age, your overall health and the stage your cancer is in when you are diagnosed. Your doctor will explain the types of treatment they feel are right for you. You may start with treating symptoms such as shortness of breath, before moving into more intensive treatment such as surgery.
Lung cancer treatment includes:
This treatment for lung cancer uses an intense stream of energy to kill cancer cells. During treatment, you lie still on a table while a machine moves around you, specifically targeting your cancer cells.
The surgeon will try to remove the lung cancer and keep as much healthy tissue intact as possible. Surgery is an option if your lung cancer hasn’t metastasized (spread to other parts of the body). Sometimes your doctor may recommend chemotherapy or radiation before surgery. The tumor can be shrunk by those treatments, and surgery can remove what’s left behind.
Types of lung cancer surgery include:
Norton Cancer Institute participates in national lung cancer clinical trials. Ask your cancer care team if a clinical trial is right for you.
Chemotherapy is an intensive lung cancer treatment medication that can be taken in a pill or via a vein in your arm (intravenously). These powerful medicines kill cancer cells. They are usually given in a series of treatments over weeks or months, with breaks in between to allow you to recover. Chemotherapy often is used with other lung cancer treatments, including surgery and radiation therapy. For people with advanced lung cancer, chemotherapy can relieve pain and other symptoms.
Targeted drug therapy focuses on specific abnormalities in cancer cells. These drugs kill lung cancer cells and often are used in patients with recurring or advanced lung cancers.
The No. 1 thing you can do to reduce your risk of developing lung cancer is to not start smoking, or to quit smoking. Ten to 15 years after quitting smoking, your risk of developing lung cancer drops by half. Within five years of quitting smoking, your risk of developing other cancers, such as throat and oral cancers, drops by half.
Other ways to reduce risk factors of lung cancer:
A Note on Vaping and Cancer Risk
While electronic cigarettes have significantly fewer harmful chemicals than regular cigarettes, they are not harmless. They still contain nicotine, the addictive substance in cigarettes, as well as potentially harmful cancer-causing substances. According to the Centers for Disease Control and Prevention, because vaping products have not been around very long, studies have been limited. The long-term effects of vaping are still not known.
Besides smoking and secondhand smoke, other causes of lung cancer include:
Lung cancer can have many complications that range from moderate to severe.
Depending on where lung cancer has spread (metastasized), it can cause pain, nausea, headaches, or other symptoms depending on what organ is affected. Once lung cancer has spread beyond the lungs, it’s generally not curable. Treatments are available to manage pain, relieve symptoms and to help you live longer.
Cancer takes a toll on your mental, emotional, and physical well-being. That’s why it is key to have support systems in place. Norton Cancer Institute treats the whole person, from diagnosis and treatment to support groups and complementary therapies. There are classes for patients as well as their caregivers. Cancer support services are offered free of charge to our patients and their families.
Unfortunately, most people don’t experience lung cancer signs right away. In fact, more than 50% of people who have lung cancer aren’t diagnosed until it has spread to other parts of the body, when it is treatable but rarely cured. That’s why early screenings are so important.
If you are experiencing lung cancer signs or are concerned that you are at an increased risk for lung cancer, talk to your physician or call (502) 629-5864 (LUNG) to speak with a patient navigator.
