The most effective way to diagnose lung cancer

summary

With the change of living environment and bad living habits, the incidence of lung cancer has been rising. In addition, people's lack of awareness of physical examination and improper physical examination methods are also the most important factors that lead to untimely diagnosis and delay of lung cancer. So what is the most effective method to diagnose lung cancer?

The most effective way to diagnose lung cancer

1、 Chest X-ray examination system: bronchial lung cancer is divided into central type and peripheral type. Peripheral lung cancer accounts for about 80%. The early diagnosis of central lung cancer mainly depends on cytology and bronchoscopy. X-ray plain film can show the secondary obstructive changes. X-ray plays an important role in the early detection of peripheral lung cancer. Although there are many complex and advanced imaging techniques, X-ray is still the preferred imaging method for lung cancer.

2、 Chest CT examination of small lung cancer: in the discovery of lesions, some reports pointed out that spiral CT than X-ray plain film showed 40% enhancement of pulmonary nodules. Because of the large amount of X-ray and high cost, this method can not be used for routine physical examination. Brain CT / MRI can also be performed: lung cancer is prone to brain metastasis, brain examination should be performed before treatment to make a clear diagnosis, MRI is better than CT.

3、 Bone scan to prevent distant metastasis of lung cancer: bone metastasis is the first symptom of patients, about 30% ~ 40% of advanced patients will have bone metastasis. The most commonly used bone imaging technique is radionuclide bone scan. CT and MRI should be used for further differential diagnosis of positive lesions, especially in patients with multiple bone metastases in load-bearing bone.

matters needing attention

For those patients who suspect that they have lung cancer, and whose CT and MRI examination are negative, the possibility of lung cancer can not be ruled out. If economic conditions permit, they can do systemic cancer screening: PET-CT. In addition to the examination, experts suggest that good attitude, healthy work and rest and physical exercise are the most effective measures to stay away from lung cancer.
