Cancer of the stomach in the elderly is a malignant tumor arising from epithelial tissue. In Russia, stomach cancer steadily ranks first among other malignant neoplasms.
Spinal cord cancer is a malignant neoplasm in the spinal cord that is in the spinal canal and is the organ of the central nervous system that provides innervation of internal organs and the performance of reflex actions.
Cancer of the sebaceous glands is extremely rare, mostly on the scalp and face. Clinically it is small, ulcerating, locally destructive, often metastasizing tumors.
Acinocellular carcinoma of the salivary gland was first considered as a serous-cellular adenoma. However, in 1954 Foote and Frazel found that this tumor is aggressive and has an infiltrative growth and metastasizes.
In the structure of cancer, penile cancer is only 0.2%. The average age of patients was 62.3 years, with a peak incidence in patients older than 75 years.
Cancer of the nasal cavity and paranasal sinuses is more common in men. Among the factors that affect the incidence of cancer in this area, professional factors also play a role.
In cancer of the mucosa of the alveolar process, the lower jaw is predominantly affected secondarily. Primary cancer of the lower jaw, which, in the opinion of some authors, arises from the dental rudiment, is extremely rare. Often, when establishing such a diagnosis, the examination reveals metastases of epithelial tumors of other localizations in the lower jaw.
Cancer of the larynx takes the first place among malignant tumors of the head and neck, accounting for 2.6% of the total incidence of malignant tumors.
Cancer of the lacrimal gland is a rare high-malignant tumor with poor prognosis. The frequency of occurrence is divided into the following histological types: adenocystic, pleomorphic adenocarcinoma, mucoepidermoid, squamous.
Periampular cancer - the cancer of the pancreatic head region develops frequently. It can come from the very head of the gland (more often from the epithelium of the ducts than from the cells of the acini), from the epithelium of the distal sections of the common bile duct, from the phater ampoule and the fater nipple, and less often from the mucous membrane of the duodenum.
Among all malignant neoplasms of internal organs, gallbladder cancer, extrahepatic ducts and pancreas constitute a special group. Their unification is due to localization in one anatomical zone, the uniformity of the functional and structural changes caused by them, as well as the similarity of pathogenetic mechanisms, clinical manifestations, complications and methods of treatment.
Cancer of the uterus body is mainly found in postmenopause. In patients with bleeding during this period of life, it is detected in 10% of cases. Diagnostic errors in women at this age are due to an incorrect evaluation of bloody discharge, which is often explained by climacteric dysfunction.
Anal oncology, or anus cancer - is a rare malignant disease. The pathology is located from the upper border of the internal anal sphincter (from the scallop line) to the dermal anal line.

Inflammation of the tubule (canaliculitis) often occurs secondary against the background of inflammatory processes of the eyes, conjunctiva. The skin in the tubule area becomes inflamed. There is marked lachrymation, mucopurulent discharge from lacrimal points.
Kampilobacteriosis is an acute zoonotic infectious disease with a fecal-oral mechanism of transmission of the pathogen, characterized by fever, intoxication, a primary lesion of the gastrointestinal tract.
Camptodactyly - a congenital defect caused by a violation of the differentiation of the tendon-muscle apparatus of the hand. Observe either isolated flexion contracture of the V finger (in 96% of cases), or combined with the flexural contraction of the II-IV fingers at the level of the proximal interphalangeal joint (in 4% of cases).
One of the hardware methods of getting rid of calluses is their destruction using such a cryo-liquid as liquefied nitrogen, which has a temperature of -195.8 ° C in this state of aggregation.
Among all the biogenic macroelements of the human body, the proportion of calcium - in the form of crystals of hydroxyapatite bone tissue - is the most significant, although blood, cell membranes and extracellular fluid also contain calcium.
Cal is all that remains of food after getting into the body. In order for the food to turn into feces, it takes from one to three days. Feces consist of undigested food, dead cells, mucus, bacteria.
