Cancer (oncology)

Adenoma of the salivary gland

The adenoma of the salivary gland in the row of benign tumors takes first place. The term "mixed tumor", proposed by R.Virkhov in 1863, reflects the opinion held by many pathomorphologists, advocates of epithelial and mesenchymal development of the tumor.

Tumor of the salivary gland

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

Photodynamic therapy of cancer

In recent years, in the treatment of cancer, more attention has been paid to developing methods such as photodynamic therapy for cancer. The essence of the method consists in the selective accumulation of a photosensitizer after intravenous or topical administration followed by irradiation of the tumor with a laser or non-laser light source with a wavelength corresponding to the spectrum of sensitizer uptake.

Cancer of the gallbladder

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.

Immunotherapy of cancer

Immunotherapy of cancer and its use in combination with radical methods of treatment of cancer patients helps improve the effectiveness of treatment, prevention of relapses and metastases.

Radiation therapy for cancer

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

Removal of a cancerous tumor

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

Cancer screening

An examination for cancer begins with the collection of complaints and anamnesis. Careful collection of complaints and anamnesis in an individual interview depends on the preparedness of the doctor and his ability to communicate with the patient.

Cancer of the stomach in the elderly

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.

What is a precancer?

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