Early screening of lung cancer is necessary for the high-risk population to ensure that early diagnosis and treatment begins. Over the years, high-risk groups such as heavy smokers have been screened for lung cancer and put to treatment early enough. The only most recommended screening test for lung cancer is the low-dose computed tomography (CT scan). Many people who show no symptoms but are viewed as being at the risk of lung cancer have been subjected to CT scans. The CT scans are medical imaging tests that are used to take the pictures of the parts of the body at various angles and allow for the viewing of detailed images of the human organs and bones. The CT scans are useful in screening and viewing the human body for those who are at risk to identify if they have lung cancer.
The presence of CT scans has taken the war against lung cancer to the next stage as people deemed to be at risks can be taken for tests to detect, diagnose and plan for the treatment for the disease. CT scans usually involve exposure to ionization radiation, which has been useful in reducing the risks of lung cancer to the high risks individuals such as heavy smokers. The CT scan tests have been useful and beneficial for the people aged 55 and above who are heavy smokers or those who recently quit smoking. While chest x-rays have always been used to diagnose lung cancer, it can sometimes miss early cancer stages, and thus, CT scan preferred. CT scans have been useful throughout all the early stages of cancer screening to detect and diagnose lung cancer. Therefore, CT scans have played a key role in making the diagnosis of lung cancer to the next stage and has led to early detection of the disease.
