Study Notes
Lung Cancer
- Lung cancer is uncontrolled cell division in lung tissue
- Cells divide uncontrollably, forming tumors
- Tumors can spread to surrounding tissues
- Common symptoms: shortness of breath, coughing (possibly blood), weight loss
- Leading causes: carcinogens (e.g., cigarette smoke), ionizing radiation, viral infections
- Smoking is the major cause; risk lower in non-smokers
- Cigarette smoke contains over 50 carcinogens
- Second-hand smoke (passive smoking) is also a cause
- Smoke from the burning end of a cigarette is more dangerous than filtered smoke
- Preventing lung cancer: eliminating tobacco smoking, preventing young people from starting, and stopping tobacco advertising
Bad Effects of Smoking
- Smoking is harmful due to over 4,000 chemicals, at least 50 of which are carcinogens, many being poisonous
- Nicotine is a powerful poison, used as insecticide historically
- Nicotine hardens artery walls and damages brain tissue
- Smoking is linked to many life-threatening diseases, not just lung cancer
- Lung cancer is a major cause of cancer-related death, estimated over 1.3 million deaths globally
- Smoking rates have declined in developed countries, but rise in developing countries (3.4% annually as of 2002 study)
- Quitting smoking decreases cancer risk as lung damage is repaired and toxins removed
