Lung Cancer Diagnostic And Screening Helps In Early Detection Of Cancer

Lung Cancer Diagnostic and Screening 

 

Screening can help prevent many cases of advanced lung cancer by finding cancers when they are smaller and easier to treat. The only screening test currently recommended is low-dose computed tomography (LDCT).

LDCT scanning uses an X-ray machine and computers to create detailed images of the chest. It is very sensitive and can detect small nodules. It also uses about 90% less radiation than a regular CT scan.

The global lung cancer diagnostic and screening market is estimated to be valued at US$ 1,931.0 million in 2020 and is expected to exhibit a CAGR of 7.8% during the forecast period (2021-2028).

Doctors will then look at the LDCT images to see whether any nodules are suspicious. If any nodules are detected, doctors will order further tests to confirm the diagnosis and determine if the cancer is in an early stage. They will also look at the results of a complete blood count (CBC) to check if the cancer cells are affecting the number and quality of other blood vessels.

If the cancer is in an early stage, doctors may use a procedure called a bronchoscopy to insert a thin tube through the mouth or nose to see inside the lungs for a tumor or blockage. During a bronchoscopy, doctors can also take tissue samples from the lungs to see if the cancer has spread. They can also use a special bronchoscope that has an ultrasound sensor, called endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), to sample lymph nodes near the trachea and bronchi in the area of the chest known as the mediastinum.

In a few well-designed, randomized controlled trials, Lung Cancer Diagnostic and Screening combined with sputum cytology was found to reduce lung cancer mortality in people who were at high risk for the disease. In these studies, participants who received screening had a much lower risk of developing advanced-stage lung cancer than did those in the control group.

More research is needed to find out the best way to do lung cancer screening, especially in different groups of people, and how to encourage participation. It is important to design programs that address cultural factors and ensure that people who are screened get the information they need to follow up on any abnormal findings.

It is also important to develop ways to improve how patients are entered into registries that track follow-up testing, radiation exposure and the status of any potential cancers. This could help enhance the benefits of screening and minimize the harms from unnecessary imaging tests.
