The main characteristic of malignant tumors is the loss of cells ability to differentiate, disruption of the structure of tissues. Malignant tumor cells “aggressive” spread by the bloodstream throughout the body, with subsequent formation of new tumor foci. Tumors are both malignant and benign. There are many varieties of cancer such as mouth cancer, lung cancer, vaginal cancer, cervical cancer, thyroid cancer, throat cancer etc In the modern world a large number of factors contribute to the process of carcinogenesis, such as:



  1. Chemical carcinogens (metals, plastics);

  2. Biological factors;

  3. Genetic factors;

  4. The environmental factors.


Cancer symptoms depend mainly on location of the tumor, from the growth and presence of metastases. Features:
