All Answers (9) As we all know, Agar is a solidifying agent. Its intended use in media based on its strength. Sometime, i use phytagel in replace of Agar (Plant media), even there are few specific for bacteriological too. You can use phytagel or agar in MS media at .7% of its concentration. Eventually, there is no difference between those two Agar, its solely depends on its intended use in combination with proper strength for cultured organism.
Lung cancer can spread to nearly any region of the body, but the most common areas are the lymph nodes, liver, bones, brain, and adrenal glands. Let's take a look at each of these areas separately. Most lung cancers first spread to lymph nodes in the chest near the tumor. As cancer progresses, cancer cells can travel to areas in the chest further from the initial tumor, and then on to other regions of the body.
As more cancer cells develop, they can form into a tumor and spread to other areas of the body. To learn more about how cancers start and spread, see What Is Cancer? Types of lung cancer. The 2 main types of lung cancer are: Small cell lung cancer (SCLC), which is sometimes called oat cell cancer. About 10% to 15% of lung cancers are SCLC. Non-small cell lung cancer (NSCLC), which makes up about 80% to 85% of lung cancers. The 3 main types of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Small cell and non-small cell lung cancers are treated differently. The information here focuses on small cell lung cancer. See Lung Cancer (Non-Small Cell) for information about that type of lung cancer. Other types of lung cancer and tumors. Lung carcinoid tumors: Less than 5% of lung tumors are carcinoid tumors of the lung. Most of these grow slowly. For more information about these tumors, see Lung Carcinoid Tumor.
