Like all other types of cancers, lung cancer develops due to an abnormality in the cells of the body. Normally, the body keeps a balance on cell growth so that body cells divide to produce new cells only when new cells are needed. An uncontrolled cell growth forms a mass called tumor.
Early diagnosis of lung cancer improves outlook and survival rates. It’s important to remain aware of the symptoms and undergo screenings as appropriate. This can improve outcomes in many lung cancer patients. Lung cancer generally does not have many early symptoms. In fact, many tumors in the lung never cause any symptoms.
Lung cancer is often tied to smoking or exposure to certain chemicals. According to available date, though there are far fewer women who smoke cigarettes than men, but they still account for about half of all new lung cancer cases. Though there has been a decline in cancer deaths in men in the last two decades, lung cancer deaths among women continue to rise.
If your doctor suspects that you may have lung cancer based on the results of a screening test or because of the symptoms you might experience, he or she will ask for tests and exams to confirm its presence. Chest X-ray is often the first test your doctor will do if you experience symptoms.
In 1989, the isolation and cloning of vascular endothelial growth factor-A was a milestone in understanding the formation of new blood vessels from the pre-existing vessels. The concept of angiogenesis then became clear. This was a major advancement that laid foundations of improved treatments for certain cancers including lung cancers.
Chemotherapy is a widely used treatment for cancer. The term ‘chemotherapy’ refers to the drugs that prevent cancer cells from dividing and growing. It works by killing the cells that divide in an uncontrolled way.
Cancer treatments can cause several changes to your body. There are some side effects of each type of cancer treatment, which different people experience differently. As you prepare yourself for cancer treatment, you may benefit from these coping strategies.
Silicosis is a long-term lung disease that is caused mainly duty to silica dust exposure. It is caused by inhaling crystalline silica dust found in sand, rock, or mineral ores like quartz. It is often referred to as a fibro-nodular lung disease.
