The United States Preventive Services Task Force (USPSTF) designed guidelines for lung cancer screening. Following these guidelines may help identify the condition early and reduce fatalities.
The USPSTF guidelines recommend annual lung cancer screening for individuals with the greatest risk of lung cancer. The early detection of lung cancer
This article discusses lung cancer in more detail and outlines the USPSTF screening guidelines for the disease. It also explores what lung cancer screening involves and treatments for the condition. Finally, it answers some common questions about this condition.
The symptoms of lung cancer can be different for each individual. But some of the more
- shortness of breath
- feeling tired or lethargic
- unexplained weight loss
- pain in the chest
- a lingering cough that may worsen over time
- coughing up blood
People with lung cancer may also have issues with ongoing pneumonia, which refers to an inflammation of one or both lungs.
Smoking cigarettes causes roughly 90% of lung cancer cases. Tobacco smoke has different chemicals that can cause this form of cancer. People with exposure to secondhand smoke are also at a higher risk of developing lung cancer.
Other substances may likewise increase the risk of lung cancer. These can include:
Finally, people with a family history of this cancer are at a higher risk of developing the disease themselves.
- are between 50 and 80 years old
- have a 20-pack year smoking history
- smoke currently or quit smoking within the last 15 years
A pack year refers to a year in which someone smokes one pack of cigarettes every day. Smoking daily for extended periods increases the risk of lung cancer considerably.
The USPSTF recommends screening people who meet these criteria every year until they have not smoked for 15 years. They also advise discontinuing screening if an individual develops a health condition that significantly reduces their life expectancy or would prohibit lung surgery.
Previous USPSTF guidelines recommend people undergo screening at the age of 55 years. The new guidelines lowered the screening age to increase the chance of detecting and successfully treating lung cancer in younger individuals.
They also reduced the number of pack years, from 30 to 20. These expanded guidelines cover more individuals at risk of lung cancer. This may ultimately help reduce the number of lives lost to this disease.
The USPSTF advises medical professionals to carry out lung cancer screening with low dose CT (LDCT) scans. An LDCT device
Taking pictures at different angles allows the computer to create 3D images. These images can show unusual changes to tissues or organs.
Catching lung cancer early dramatically improves the chances of responding to treatment. With LDCT screening, doctors can recognize the early signs of lung cancer before it has spread.
Research shows that LDCT screening
This is why LDCT screening is recommended only for those already at high risk of developing lung cancer. For these individuals, LDCT may help catch lung cancer early and lead to successful treatment.
- undergoing surgery
- receiving radiation therapy or chemotherapy
- participating in a clinical trial
- targeted therapy
The treatment also depends on the type of lung cancer. In the early stages, surgery alone
The journey through lung cancer is highly personal. Treatment plans
Below are some of the most common questions and answers about lung cancer.
Should people who smoke have lung cancer screening?
According to the USPSTF, people who have
An individual who smoked one pack every day for 20 years would be eligible for screening. Alternatively, someone who smoked two packs daily for a decade would also be eligible.
Can a blood test detect lung cancer?
Blood tests are
They may also order a complete blood count test. This test can detect abnormalities in different blood cell types. This could warn the doctor of potential issues with bleeding or infections during lung cancer treatment.
Is lung cancer treatable if doctors find it early?
The LDCT screening test
Research indicates that people who receive an early diagnosis have around a 56% likelihood of survival 5 years following their diagnosis. However, the overall 5-year survival rate for lung cancer is 18.6%.
Although lung cancer is the leading cause of death from cancer, early detection increases the chance of making a full recovery.
Older individuals with a long history of smoking are at a particularly high risk of developing lung cancer. The USPSTF lung cancer screening guidelines recommend an annual screening for these people.
This screening may detect lung cancer before it causes symptoms. Starting treatment in the early stages of this disease increases the chance of recovery.
