Cancerstands for a collection of diseases affecting the body cells. Whencancer develops, cell division becomes disorderly as the old anddamaged cells survive when they should die, and at the same time, newcells are formed when they are not needed. Cancerous tumors aremalignant, meaning they can invade or spread into the surroundingtissues. Unlike other normal cells, the cancer units do not grow intodistinct cell types with specific functions, and this is the primaryreason they continue to divide without stopping.

Lungcancer is one of the most common and is currently the leading causeof cancer deaths not only in the United States but in the wholeworld. Recent statistic shows that about 1 out of 4 deaths resultingfrom cancer are lung related. It is also important to point out thatthe risk of developing lung cancer is higher among the elderly peoplewho smoke cigarettes than their non-smokers counterparts. Otherfactors which can increase chances of acquiring cancer include familyhistory, environmental contamination with high levels of radioactivegases, and exposure to asbestos and other toxic chemicals.

Althoughlung cancers tend to spread very early, however less than 20% aredetected during the initial stages (Carbone et al, 2010). The cancercan spread to another part of the body through a process referred toas metastatic. For instance, lung cancer spreading to the brain iscalled lung cancer metastatic to the brain. One can reduce chances ofcancer through eating healthy balanced diet, physical exercises, andregular medical checkups among others. There is also the need forgovernments and stakeholders to carry out civic education, as thiswill help in sensitizing people on the need for regular checkups.
