Non-small cell lung cancer (NSCLC) is the most common type of lung cancer.What are the subtypes of NSCLC?Squamous cell carcinoma is found in cells that line the airways of the lungs. It is usually found in the middle of the lung. Adenocarcinoma is found in cells that produce mucus. It...
Small cell lung cancer (SCLC), sometimes referred to as "oat-cell carcinoma," occurs when the cells in your lungs start to grow unusually or uncontrollably. This unusual growth takes place inside your lungs or the lining of the airways. As more cancer cells grow, they can form into a tum...
First, you breathe in medical gas. Then, contrast liquid is injected into a vein. Pictures are taken to see how well your lungs take in oxygen.How is a PE treated?Treatment depends on what the embolus is made of and where the PE is located in your lung. You may need any of the ...
The location of the nodule in your lungs can also be informative. Nodules in the lower parts of your lungs are more likely to be benign (non-cancerous) compared to those in the upper parts of your lungs The structure of the nodule helps the doctor decide what to do next. Lung nodules...
They’re poisonous to the cells in your lungs. We’re not sure yet if vaping causes lung cancer. The vapor from e-cigarettes does contain chemicals that are known to cause cancer, but in lesser amounts than you find in cigarettes. If you vape, you may become addicted to nicotine or ...
Some studies of laboratory animals and cells grown outside the body suggest that there are reasons for concern about how these minuscule pieces of plastics affect our physiology. What remains less apparent is what risks to health, if any, these tiny particles pose at the concentrations they’ve...
Chronic, wet, productive cough especially in the morning Shortness of breath Weakness Lung cancer It is the leading cause of death in the United States. Lung cancer refers to the uncontrolled growth of cells that starts in the lungs. It affects the air sacs of the lungs and may spread ...
When there is an abnormal growth of cells in the tissues of the lungs, it results in lung cancer. As a consequence, this could lead to a condition referred to as metastasis which means the spreading of cancer, outside the lungs, to other parts of the body. When the lungs become cancer...
Simple squamous: These cells form a thin, single layer that creates a membrane. They are found in the walls of your capillaries, along the linings of the alveoli in yourlungs, and in the linings of the pericardium. Simple columnar: These tall cells are packed together to form a row. You...
The lungs are made up of several tissues and cell groups that perform the vital action of respiration. Respiration is a central function in humans. Respiration is the biological process in which food and oxygen are converted into energy for cellular grow
