Cavitary lung cancer is formed by secondary infection or ischemic necrosis of the tissue at the center of the cancer, or in some cases, by malignant transformation of cavitary tuberculosis into lung cancer.
Cavitary lung cancer is mostly seen in lung cancers over 4 cm in diameter, and small lung cancers up to 2 cm in diameter usually do not develop cavities; lung cancer is usually examined by CT or enhanced CT of the lung, and some require PET-CT, and puncture biopsy or pathological tissue examination via thoracoscopy is the ultimate means to confirm the diagnosis of lung cancer. Currently, the main treatment for lung cancer is surgery with postoperative radiotherapy and chemotherapy, and some of them require targeted therapy.
The formation of lung cancer is related to long-term smoking, air pollution, exposure to harmful toxic substances and ionizing radiation, etc. The incidence of lung cancer is significantly higher in long-term smokers than in non-smokers, so for the sake of health, avoid auto-smoking or second-hand smoke as much as possible.
The earlier lung cancer is detected, the better the treatment effect, especially early lung cancer, which can be clinically curable, so people at high risk for lung cancer should have annual lung exams.
