A canal is a man-made waterway. Canals are built for a variety of uses including irrigation, land drainage, urban water supply, hydroelectric power generation, and transportation of cargo and people. Navigation canals may be shallow facilities designed for barge traffic, or they may be deep enough to accommodate ocean-going ships.
The majority of small cell lung cancer cases are oat cell type. Although the cancer cells are smaller in size compared to non-small cell lung cancers (NSCLC), which make up 85 to 90 percent of all lung cancers, SCLC grows quickly and produces large tumors.
Lung cancer is the leading cause of cancer death in the United States, with an estimated 221,200 new diagnoses and 158,040 deaths in 2015, according to the National Cancer Institute. The most common type of lung cancer, NSCLC occurs when cancer cells form in the tissues of the lung.
