AB Neoplasia  (Latin,  new  growth)  is  an  abnormality  of  cellular  differentiation,  maturation,  and  control  of  growth.  Neoplasms  are  commonly  recognized  by  the  formation  of  masses  of  abnormal  tissue  (tumors).  The  term  tumor  can  be  applied  to  any  swelling—and  in  that  context  is  one  of  the  cardinal  signs  of  inflammation—but  today  it  is  used  most  commonly  to  denote  suspected  neoplasm.  Neoplasms  are  benign  or  malignant  depending  on  several  features,  chiefly  the  ability  of  malignant  neoplasms  to  spread  from  the  site  of  origin.  Benign  neoplasms  grow  but  remain  localized.  Cancer  denotes  a  malignant  neoplasm  (the  term  is  thought  to  derive  from  the  way  in  which  the  tumor  grips  the  surrounding  tissues  with  claw-like  extensions,  much  like  a  crab).
