AB Neoplasms  are  diseases  characterized  by  abnormal  proliferation  of  cells.  If  the  proliferating  cells  invade  surrounding  tissues,  the  resultant  tumor  is  malignant;  if  they  do  not,  it  is  benign.  Some  benign  neoplasms  may  be  fatal,  including  histologically  benign  brain  tumors  that  grow  and  displace  normal  brain  tissue  in  the  confined  space  of  the  skull,  and  hepatocellular  adenomas  that  rupture  and  cause  bleeding  into  the  peritoneal  cavity.  Some  benign  tumors  such  as  intestinal  polyps  are  considered  premalignant  lesions  and  confer  a  high  risk  of  progression  to  malignancy.  The  term  cancer  usually  implies  a  malignant  tumor  (malignancy),  but  refers  also  to  brain  tumors  and  some  other  benign  neoplasms.
