What is the difference between peripheral lung cancer and cancer in situ?

The difference between peripheral lung cancer and carcinoma in situ includes the location of the disease, the population of the disease, and the way of growth.

1. The location of the disease Peripheral

lung cancer occurs in the outer edge of the lung tissue, and carcinoma in situ occurs in the inner epithelial cells of the lung.

2. The population of the disease

Peripheral lung

cancer is more common in the elderly, and carcinoma in situ is more common in middle-aged people.

3. The way of growth

Peripheral lung cancer is mostly solid, composed of solid cancer cells, and the distribution of cancer cells is usually loose. Carcinoma in situ is mostly based on alveoli, and cancer cells are more closely arranged in or near the alveoli.
