At the beginning, healthy individuals who have contracted the lung cancer may not suspect the presence of the disease in their lungs because initially, the disease is almost symptomless. So both smokers and non smokers who are at risk can go for lung cancer diagnosis tests to determine whether they have contracted lung cancer or not.
Sometimes, doctors may be in dilemma whether to subject people with not visible signs of lung cancer to diagnostic tests or not. Even when you are at risk, there is no guarantee that the tests will be beneficial in all cases. The reason is that the results may be reveal benign signs of manifestation. However, this is not satisfactory to convince the doctor that one needs to be put on medication or undergo treatment. Further probing and tests may be carried out to determine the nature of the cancer.
There seems to be controversy surrounding some of the lung cancer tests such as screening. This comes at a time when further research is being conducted to determine the suitability of certain screening procedures. In spite of this, you still have the right to discuss with your oncologist or physician about the nature of the disease and the relevant tests that you should undergo.
In some instances, it may not be advisable to be subjected to a combination of lung cancer diagnosis tests. This is true when you suspect benign manifestation of the disease. Some of the tests such as CRT imaging may pose certain health risks and so you should avoid it unless your doctor finds it’s necessary for you to undergo the test.
However, if you are convinced beyond reasonable doubt that you are at high risk of developing cancer because of your lifestyle, then you can consult a physician. After discussions, the physician may recommend a few tests to determine whether you have contracted the disease or not. If the results are positive, then further tests may be done to determine the extent of manifestation of the disease in your lungs and other organs.
One of the foremost tests that your doctor can undertake is imaging tests. In this form of examination, x-rays are used to capture images of abnormal growth in the lungs. Alternatively, CT scans can be used to reveal the presence of such things as lesions that may not be captured by x-ray imaging.
The physician may also conduct sputum cytology tests. This test basically examines the content of the sputum under microscope. This test is important in revealing the presence or cancer cells. Furthermore, the physician may perform biopsy tests to diagnose lung cancer by removing a small tissue of the cancerous growth from the liver or lymph nodes for further probing and examination.
This type of lung cancer diagnosis may involve the use of procedures such as bronchoscopy where the physician examines the lungs using a small tube camera inserted into the lungs. Alternatively, the physician may also collect samples from specific areas with suspicious growth using needle biopsy which incorporates guided imaging procedures such as CT scans on the lungs.
