| colorectal | <anatomy> Pertaining to or affecting the colon and rectum. (18 Nov 1997) |
|---|---|
| colorectal cancer | <oncology> A malignancy that arises from the lining of either the colon or the rectum. Cancers of the large intestine are the second most common form of cancer found in males and females. Symptoms include rectal bleeding, occult blood in stools, bowel obstruction and weight loss. Treatment is based largely on the extent of cancer penetration into the intestinal wall. Surgical cures are possible if the malignancy is confined to the intestine. Risk can be reduced when following a diet which is low in fat and high in fibre. (27 Sep 1997) |
| colorectal surgeon | <specialist> A specialist that is expert in the surgical care of colorectal disease (for example haemorrhoids, cancer). (11 Mar 1998) |
| bladder neoplasms | Cancers or tumours of the bladder. The majority of bladder neoplasms are of the transitional cell variety and are usually papillary and multicentric. (12 Dec 1998) |
| bone marrow neoplasms | Neoplasms located in the bone marrow. They are differentiated from neoplasms composed of bone marrow cells, such as myeloma. most bone marrow neoplasms are metastatic. (12 Dec 1998) |
| breast neoplasms, male | Any neoplasms of the male breast. These occur infrequently in males in developed countries, the incidence being about 1% of that in females. Two-thirds of patients present with intraductal carcinoma. The average age of onset is 60 years for men. Orchiectomy was the standard treatment but it has been replaced by tamoxifen as the initial therapy since oestrogen-receptor-positive tumours are predominant in males. Orchiectomy and mastectomy may be used if initial drug therapy is not successful. The prognosis is worse than that for females. (12 Dec 1998) |
| vascular neoplasms | <oncology> Neoplasms located in vascular tissue or specific veins. They are differentiated from neoplasms, vascular tissue which are neoplasms composed of vascular tissue, such as angiofibroma or haemangioma. (12 Dec 1998) |
| pancreatic cystic neoplasms | <radiology> Microcystic adenoma, glycogen, benign, mucinous cystic neoplasm, macrocystic adenoma, cystadenoma/cystadenocarcinoma, mucin, pre-malignant, Both occur more commonly in women, peak in middle age (12 Dec 1998) |
| pancreatic neoplasms | <radiology> Adenocarcinoma, most common, usually in pancreatic head, nasty (1-2% survival at 1 yr!), cystic neoplasms, slow-growing, more common in women, isleT-cell tumours, soft-tissue tumours (rare), metastases (breast, lung, melanoma, stomach, colon) (12 Dec 1998) |
| mammary neoplasms | Tumours of the mammary gland. Their occurrence is uncommon with the exception of the female dog, in which they account for 25% of all neoplasms. (12 Dec 1998) |
| paranasal sinus neoplasms | Neoplasms or tumours of the paranasal sinuses. Malignant neoplasms are rare, comprising 3% of all head and neck neoplasms. The majority arise in the maxillary sinus with malignancies of the ethmoid sinus constituting virtually all the remaining tumours. (12 Dec 1998) |
| genital neoplasms, male | Neoplasms of the male genitalia. (12 Dec 1998) |
| maxillary neoplasms | Cancer or tumours of the maxilla or upper jaw. (12 Dec 1998) |
| maxillary sinus neoplasms | Neoplasms or tumours of the maxillary sinus. The majority of paranasal sinus neoplasms arise here. They develop silently when confined to the sinus and produce symptoms on extension through the walls. (12 Dec 1998) |
| central nervous system neoplasms | Neoplasms located in the brain, spinal cord, or meninges. (12 Dec 1998) |
