Consists of all the organs in our body cells. Smallest cells of our body and yapıtaşlarıdır but can be seen with microscope. Healthy body cells (except for muscle and nerve cells) are capable of divisibility. Renewal of cells and tissues of the deceased injured (inside and outside the body) will be repaired in order to use these capabilities. But it also has limited capabilities. Can not be infinitely divisible. Throughout his life a certain number of each cell is apportioned. Where necessary and a healthy cell to divide as needed knows. In contrast, cancer cells, it loses consciousness, starts to divide and grow uncontrolled. Cancer cells accumulate in the tumors (masses) form, tumors can compress normal tissue, can penetrate into the can or destroyed. If the cancer cells formed tumors that leaves the blood or lymph circulation to other parts of the body can go through. They go places and creates tumor colonies continue to grow. In this way the cancer spread to other parts of the body is called metastasis to the event. Cancers begin to occur, they are classified according to the organs and appearance under the microscope. Different types of cancers, grow at different speeds, different display formats and they spread their response to different treatments. Therefore, in the treatment of cancer patients, existing treatments are applied differently depending on the type of cancer.
