| cervical polyps | A benign growth projecting from the mucosa of the cervix. The cause is unknown but may be associated with local inflammation. They are more common in women over 20 who have had children. Some may cause bleeding and interfere with normal menstrual cycles. Diagnosis is by physical examination (pelvic exam). A PAP smear will be recommended since some cervical cancers may appear as a polyp. Treatment is surgical removal. (27 Sep 1997) |

| colon cancer and polyps | Benign tumours of the large intestine are called polyps. Malignant tumours of the large intestine are called cancers. Benign polyps do not invade nearby tissue or spread to other parts of the body. Benign polyps can be easily removed during colonoscopy, and are not life threatening. If benign polyps are not removed from the large intestine, they can become malignant (cancerous) over time. most of the cancers of the large intestine are believed to have developed from polyps.

| polyps | A general descriptive term used with reference to any mass of tissue that bulges or projects outward or upward from the normal surface level, thereby being macroscopically visible as a hemispheroidal, spheroidal, or irregular moundlike structure growing from a relatively broad base or a slender stalk. Classically applied to a growth on the mucous membrane of the nose, the term is now applied to such protrusions from any mucous membrane. (12 Dec 1998) |
| nasal polyps | Focal accumulations of oedema fluid in the nasal mucosa accompanied by hyperplasia of the associated submucosal connective tissue. Polyps may be neoplasms, foci of inflammation, degenerative lesions, or malformations. (12 Dec 1998) |
| intestinal polyps | Pedunculated or sessile growths arising from the intestinal mucosa and extending into the lumen. The disease includes intestinal polyposis. (12 Dec 1998) |
| genes, recessive | Genes that are reflected in the phenotype only in the homozygous state. (12 Dec 1998) |
| recessive | <genetics> An allele or mutation that is only expressed phenotypically when it is present in the homozygous form. In the heterozygote it is obscured by dominant alleles. (18 Nov 1997) |
| recessive character | An inherited character determined by an allele in homozygous state only. See: dominance of traits. (05 Mar 2000) |
| recessive gene | A gene that is expressed onlywhen it is present in two copies or if theother copy is missing. (09 Oct 1997) |
| recessive inheritance | dominance of traits |
| recessive oncogene | <molecular biology> A single copy of this gene issufficient to suppress cell proliferation, the loss of both copies of the gene contributes to cancer formation. (09 Oct 1997) |
| recessive trait | See: dominance of traits. (05 Mar 2000) |
| recessive, x-linked | A gene on the X chromosome that expresses itself only when there is no different gene present at that locus (spot on the chromosome). For example, duchenne muscular dystrophy (dmd) is an x-linked recessive disorder. A dmd boy has the dmd gene on his sole x chromosome (and so is said to be hemizgous for dmd). Although it is much rarer, a girl can have dmd (by several different means as, for example, if she has the dmd gene on both her x chromosomes and so is homozygous for dmd). (12 Dec 1998) |
| benign familial chorea | A rare, nonprogressive movement disorder characterised by chorea and athetosis appearing in early childhood, most commonly manifested as gait ataxia and upper limb coordination. Intellect is unaffected. Probably autosomal-dominance inheritance with incomplete penetrance. (05 Mar 2000) |
| benign familial chronic pemphigus | Recurrent eruption of vesicles and bullae that become scaling and crusted lesions with vesicular borders, predominantly of the neck, groin, and axillary regions; autosomal dominant inheritance, presenting in late adolescence or early adult life. Synonym: Hailey-Hailey disease. (05 Mar 2000) |
