Lung cancer: Lung cancer begins in the lungs and may spread to lymph nodes or other organs in the body, such as the brain. Cancer from other organs also may spread to the lungs. When cancer cells spread from one organ to another, they are called   metastases. Lung cancers usually are grouped into two main types called small cell and non-small cell (including adenocarcinoma and squamous cell carcinoma). These types of lung cancer grow differently and are treated differently. Non-small cell lung cancer is more common than small cell lung cancer  Causes: 1. Smoking: Cigarette smoking is the leading cause of lung cancer. It is responsible for the majority of cases, and the risk increases with the duration and intensity of smoking. 2 . Secondhand smoke : Being exposed to tobacco smoke from others can also increase the risk of developing lung cancer. 3. Radon gas: Exposure to high levels of radon, a naturally occurring radioactive gas that can seep into buildings, can increase the ...

Angina or Heart Pain: Angina is a condition characterized by chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. It is usually a symptom of an underlying heart condition, most commonly coronary artery disease (CAD), where the blood vessels supplying the heart become narrowed or blocked by a buildup of fatty plaques. Causes: 1. Coronary artery disease (CAD): The primary cause of angina is the narrowing of the coronary arteries due to plaque buildup, reducing blood flow to the heart. 2. Spasm of coronary arteries : In some cases, the coronary arteries may spasm and temporarily restrict blood flow to the heart, causing angina. 3. Other factors: Angina can also be triggered by conditions such as aortic valve disease, high blood pressure, heart failure, or anemia. Symptoms: The most common symptom of angina is chest pain or discomfort. The pain is often described as a squeezing, pressure, heaviness, or tightness in the chest. Other symp...
