Cancer (oncology)

Salivary gland adenoma

Adenoma of the salivary gland ranks first among benign tumors. The term "mixed tumor" proposed by R. Virchow in 1863 reflects the opinion held by many pathomorphologists, supporters of epithelial and mesenchymal tumor development.

Salivary gland tumor

Epidemiological and statistical data concerning such a disease as salivary gland tumor have not been registered until recently. The main reasons for this fact were: lack of separate statistical records; association with other malignant neoplasms of the upper digestive tract, as well as statistical errors, demographic differences and other local factors.

Photodynamic therapy for cancer

In recent years, in the treatment of oncological diseases, increasing attention has been paid to the development of methods such as photodynamic cancer therapy. The essence of the method lies in the selective accumulation of a photosensitizer after intravenous or local administration, followed by irradiation of the tumor with a laser or non-laser light source with a wavelength corresponding to the absorption spectrum of the sensitizer.

Gallbladder cancer

Among all malignant neoplasms of internal organs, cancer of the gallbladder, 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 they cause, as well as the similarity of pathogenetic mechanisms, clinical manifestations, complications and treatment methods.

Cancer immunotherapy

Cancer immunotherapy and its use in combination with radical methods of treating cancer patients helps improve the effectiveness of treatment, prevent relapses and metastases.

Radiation therapy for cancer

Radiation therapy for cancer is a treatment method using ionizing radiation. Currently, about 2/3 of cancer patients require this type of treatment.

Removing a cancerous tumor

Surgical removal of a cancerous tumor remains the most common. It is used for almost all oncological diseases as an independent method, as well as in combination with radiation and drug therapy.

Cancer screening

Cancer examination begins with collecting complaints and anamnesis. A thorough collection of complaints and anamnesis during an individual interview depends on the doctor's preparation and his ability to communicate with the patient.

Stomach cancer in the elderly

Stomach cancer in the elderly is a malignant tumor arising from epithelial tissue. In Russia, stomach cancer consistently ranks first among other malignant neoplasms.

What is precancer?

The morphogenesis of tumors, or the mechanism of their development in morphological terms, can be divided into precancer and the stage of tumor formation and growth.
