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. Lung cancer (cancer of the lung) is common worldwide. Around 8 in 10 cases develop in people over the age of 60 years, usually in smokers. If lung cancer is diagnosed at an early stage, there is a chance of a cure. In general, the more advanced the cancer (the more it has grown and spread), the less chance that treatment will be curative.
