Explanation:
Carcinoma are a type of cancer that arise from the cells that cover external and internal body surfaces, epithelial tissues. They constitute 90% of cancer.
Carcinomas occur when the DNA of a cell is damaged or altered and the cell begins to grow uncontrollably and become malignant. Mutations on the tumour suppressor gene and oncogene causes the uncontrolled cell proliferation. Oncogene accelerates the cancerous cell growth.
Examples: lung, breast, colon, prostate, pancreas, skin
