Scissor can be construed

For much of the second phase of his career, American cyclist Lance Armstrong faced constant allegations of doping, including doping at the Tour de France and in the Lance Armstrong doping case. Armstrong vehemently denied allegations of using performance enhancing drugs for 13 years, until a confession during a broadcast interview with Oprah Winfrey in January 2013, when he finally admitted to all his cheating in sports, stating, \"I view this situation as one big lie that I repeated a lot of times\".

Metaplasia is the transformation of a cell type to another cell type. The change from one type of cell to another may be part of a normal maturation process, or caused by some sort of abnormal stimulus. In simplistic terms, it is as if the original cells are not robust enough to withstand their environment, so they transform into another cell type better suited to their environment. If the stimulus causing metaplasia is removed or ceases, tissues return to their normal pattern of differentiation. Metaplasia is not synonymous with dysplasia, and is not considered to be an actual cancer. It is also contrasted with heteroplasia, which is the spontaneous abnormal growth of cytologic and histologic elements. Today, metaplastic changes are usually considered to be an early phase of carcinogenesis, specifically for those with a history of cancers or who are known to be susceptible to carcinogenic changes. Metaplastic change is thus often viewed as a premalignant condition that requires immediate intervention, either surgical or medical, lest it lead to cancer via malignant transformation.
