Trắc nghiệm Reading tiếng Anh lớp 10 Unit 2 Your Body And You

The overgrowth of cells leads to the development of tumors and the harmful effects of cancer. In lung cancer, this pattern of cell overgrowth occurs in the lungs, which are vital organs for breathing and gas exchange. Doctors typically diagnose two lung cancer types, small cell and non-small cell, depending on how they appear under a microscope. A person is more likely to have non-small cell lung cancer than small cell.

While anyone can develop lung cancer, cigarette smoking and exposure to smoke can increase the likelihood that a person will experience the condition. Lung cancer can develop if a person has a history of exposure to inhaled chemicals or other toxins. Even if this exposure to chemicals and other toxins was a long time ago, it could cause changes in lung cells that lead to cancer.

If a doctor identifies a suspicious lesion on an imaging study, they may recommend taking a sample of lung tissue to test for potentially cancerous cells. There are different ways to take a tissue sample, and the method often depends on the location of the lesion. One example is when a doctor performs a bronchoscopy, which involves inserting a special thin, lighted scope with a camera on the end. This helps the doctor to see the lesion and then to obtain samples. Less accessible lesions in the lungs may require a more invasive surgical procedure to remove lung tissue, such as thoracoscopy or video-assisted thoracic surgery.

Question 1: The effect of cancer is the result of the overgrowth of cells.

Question 6:

Chronic respiratory diseases (CRDs) are diseases of the airways and other structures of the lung. Some of the most common are chronic obstructive pulmonary disease (COPD), asthma, occupational lung diseases and pulmonary hypertension. In addition to tobacco smoke, other risk factors include air pollution, occupational chemicals and dusts, and frequent lower respiratory infections during childhood. CRDs are not curable, however, various forms of treatment that help dilate major air passages and improve shortness of breath can help control symptoms and increase the quality of life for people with the disease. The WHO Global Alliance against CRDs (GARD) has a vision of a world in which all people breathe freely, and focuses in particular on the needs of people with CRDs in low-income and middle-income countries.
