What reason is calcification focus of left upper lung?

summary

Calcified soap in the lung does not represent lung cancer. Usually, calcified soap in the lung is due to traces left by tuberculosis, especially calcified soap in the two upper lungs. At this time, the X-ray diagnosis is usually old tuberculosis. Even if it is not caused by tuberculosis, calcification may not be the manifestation of lung cancer, but may be the result of other diseases. Lung cancer can form cavity in the lung, which has its own characteristics. In some cases, calcification may indicate the presence of lung cancer. Let's take a look at the following.

What reason is calcification focus of left upper lung?

First, there are obvious differences between the cavity of lung cancer and that of benign diseases, which are easy to distinguish. The cavity wall of lung cancer is relatively thick, and the cavity is located in the eccentric position. The wall of the cave is irregular. I feel there is something like burr.

Second: the two most common types of lung cancer are adenocarcinoma and squamous cell carcinoma. Generally, men are prone to squamous cell carcinoma, which may be related to their smoking. Women are prone to adenocarcinoma. There is also a kind of small cell lung cancer. The imaging of the formation in the lung is like cotton, not limited to one place. The malignant degree of small cell lung cancer is the highest.

Third, the wall of the benign cavity is smooth and not eccentric, and the wall is thin. These are the general differentiation points of benign cavity and cancerous cavity, and specific diseases also have the characteristics of differentiation. The manifestations of different types of lung cancer are also different, especially in the nuclear medicine examination, usually can be distinguished.
