In anatomy, a polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated; if it is attached without a stalk, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus. They may also occur elsewhere in the body where there are mucous membranes, including the cervix, vocal folds, and small intestine. Some polyps are tumors (neoplasms) and others are non-neoplastic, for example hyperplastic or dysplastic, which are benign. The neoplastic ones are usually benign, although some can be pre-malignant, or concurrent with a malignancy. The name is of ancient origin, in use in English from about 1400 for a nasal polyp, from Latin polypus through Greek. The animal of similar appearance called polyp is attested from 1742, although the word was earlier used for an octopus. Digestive polyps

Colorectal polyp
While colon polyps are not commonly associated with symptoms, occasionally they may cause rectal bleeding, and on rare occasions pain, diarrhea or constipation. They are a concern because of the potential for colon cancer being present microscopically, and the risk of benign colon polyps becoming malignant over time. Since most polyps are asymptomatic, they are usually discovered at the time of colon cancer screening.
He wrote that they usually were the subject of desire when a weak person "makes use of such substitutes" or when an uncontrollable instinct which will not allow delay seeks immediate gratification and cannot find a more appropriate object.In 1908, Swiss neuroanatomist and psychiatrist Auguste Forel wrote of the phenomenon, proposing that it be referred to it as "Pederosis", the "Sexual Appetite for Children". Similar to Krafft-Ebings work, Forel made the distinction between incidental sexual abuse by persons with dementia and other organic brain conditions, and the truly preferential and sometimes exclusive sexual desire for children. However, he disagreed with Krafft-Ebing in that he felt the condition of the latter was largely ingrained and unchangeable.The term pedophilia became the generally accepted term for the condition and saw widespread adoption in the early 20th century, appearing in many popular medical dictionaries such as the 5th Edition of Stedmans in 1918. In 1952, it was included in the first edition of the Diagnostic and Statistical Manual of Mental Disorders. This edition and the subsequent DSM-II listed the disorder as one subtype of the classification "Sexual Deviation", but no diagnostic criteria were provided. The DSM-III, published in 1980, contained a full description of the disorder and provided a set of guidelines for diagnosis. The revision in 1987, the DSM-III-R, kept the description largely the same, but updated and expanded the diagnostic criteria. Law and forensic psychology

Pedophilia is not a legal term, and having a sexual attraction to children is not illegal.
