Lung cancer is the uncontrolled growth of abnormal cells in the lung. Normal lung tissue is made up of cells that are programmed by genes to create lung tissue in a certain shape and to perform certain functions lung cancer develops when the genetic material which is responsible for production of lung cells is damaged called genetic mutations. This paper represents a computer assisted diagnosis system of lung cancer that demonstrates spreading of tumors and damage of lungs if the patient neglects it. This work is based on one of the image processing techniques called image enhancement involving Contrast stretching algorithm. The local and global contrast stretching techniques are used to find better solution. The results obtained and the statistical analysis demonstrates the distribution of tumors over lungs and educate the patients towards precaution and medication. The statistical values are calculated using MIPAV software.
