What Is Lung cancer?
Understanding lung cancer seniors screening is important for seniors and their caregivers. lung cancer is a disease in which cells in the lungs grow out of control. It may spread to lymph nodes or to other organs in the body, such as the brain. Cancer from other organs may also spread to the lungs. When cancer cells move to a new place in the body, they are called metastases. Cigarette smoking is the most common cause of lung cancer, and it is the leading cause of cancer death in the United States.
What Are the Different Types of Lung Cancer?
Lung cancers are grouped into two main types: non-small cell and small cell. Non-small cell lung cancer is the most common type. It usually grows more slowly and often does not cause symptoms until it is advanced.
The three types are adenocarcinoma, which begins in the cells of the air sacs that make mucus; squamous cell carcinoma, which forms in the thin, flat cells lining the large airways; and large cell carcinoma, which starts in cells lining the lung surface and grows quickly. Small cell lung cancer is less common and spreads to other parts of the body quickly. Treatment depends on the type of cancer, how far it has spread, and your age and overall health.
📖 What Is Symptoms to Watch For?
What Is Symptoms to Watch For?
Lung cancer often has no symptoms in its early stages. When symptoms appear, they can include a cough that does not go away or gets worse, coughing up blood, chest pain that is worse with deep breathing or coughing, hoarseness, shortness of breath, wheezing, unexplained weight loss, and frequent lung infections such as bronchitis or pneumonia. If you have any of these symptoms, especially a cough that lasts more than a few weeks, see your health care provider. Many of these symptoms can also be caused by other conditions, so testing is important.
📖 What Are the Common Causes and Risk Factors?
What Are the Common Causes and Risk Factors?
Smoking is the number one risk factor for lung cancer, and the risk increases with the number of years and packs smoked. Other risk factors include exposure to secondhand smoke, radon gas in the home, asbestos, air pollution, and a family history of lung cancer. Older adults are more likely to be diagnosed because lung cancer is most common after age 65, and people who smoked for many years carry higher risk. Even people who never smoked can develop lung cancer, most often due to radon exposure, secondhand smoke, or other factors.
📖 What Are Screening Saves Lives?
What Are Screening Saves Lives?
Screening is recommended only for adults who are at high risk. The U.S. Preventive Services Task Force recommends yearly lung cancer screening with low-dose computed tomography (LDCT) for adults aged 50 to 80 who have a 20 pack-year smoking history and currently smoke or have quit within the past 15 years. A pack-year is calculated by multiplying the number of packs smoked per day by the number of years smoked. Screening finds cancer earlier, when it is easier to treat. Talk to your doctor about whether you qualify for screening.
📖 What Is Reducing Your Risk?
What Is Reducing Your Risk?
- If you smoke, quitting is the single most important step. It is never too late to benefit from quitting.
- Get your home tested for radon, a colorless, odorless gas that is the second leading cause of lung cancer.
- Avoid secondhand smoke, and ask family members to smoke outside.
- Limit exposure to air pollution, asbestos, and workplace carcinogens.
- Eat a healthy diet and stay physically active to support overall health.
- If you qualify, get yearly lung cancer screening with LDCT.
📖 What Is Treatment and Support?
What Is Treatment and Support?
Treatment depends on the type and stage of lung cancer and may include surgery, radiation therapy, chemotherapy, targeted therapy, or immunotherapy. Many people live with lung cancer for years, and supportive care helps manage symptoms and side effects. If you are diagnosed, build a care team you trust, bring a family member or friend to appointments, and ask about clinical trials and support groups.
📖 What Are Frequently Asked Questions?
What Are Frequently Asked Questions?
Q: Can people who never smoked get lung cancer?
A> Yes. Lung cancer can be caused by risk factors other than smoking, including radon exposure and secondhand smoke.
Q: Should I get screened for lung cancer?
A> Screening is recommended for adults aged 50 to 80 with a 20 pack-year smoking history. Talk to your doctor to see if you qualify.
Q: Is it worth quitting smoking at my age?
A> Yes. Quitting at any age improves health, reduces lung cancer risk, and benefits the heart and lungs.
Q: What is radon and how do I test for it?
A> Radon is a colorless, odorless gas that can enter homes through the ground and is the second leading cause of lung cancer. Low-cost test kits are available at hardware stores.
