What is malignant transformation?

Malignant transformation is a cellular change from normal or benign to cancer. Transformed cells have several features that postpone them from other types of cells, including prolonged life or immortality, where they do not die as normal cells, and rapid division and proliferation. As the cells grow and divide, they evolve on a cancer tumor that can attack neighboring tissues unless identified and treated. Understanding science for malignant transformation is the key to preventing and effective treatment of cancer. Benign tumors can be very common and in some cases are not recorded until the patient dies and the body is dissecting. These growth do not have the capacity for metastases associated with cancer growth and can be left in place when they are identified if they do not cause any problems. When cancerinunas becomes invasive and can pose a threat to the patient. This process is the result of changes in the genetic code of the cell. Some genes usually control cell division, growth, maturation and death. In the course of malignant tRansformation are turned off some genes, while others are turned on and changes the nature of cellular deoxyribonucleic acid (DNA). The cell and all its offspring become cancer and because the cells do not blame, as a normal, tumor can grow over time.

In the laboratory environment, scientists study different factors that seem to play a role in malignant transformation. They may include environmental exposure to chemicals and radiation along with random mutations, some of which are the result of genetic predisposition. For example, some families have a history of breast cancer associated with specific gene mutations. Nezéžilia cancer, but may increase the likelihood that the patient will develop cancer.

The immune system sometimes identifies symptoms of malignant transformation and can attack cancer cells. Induces cellular death and relies on metabolism to distribute the participating cells or cells, recycled urye components and destroyed waste materials. In other cases, the immune system cannot identify cancer or unable to attack cells. As the tumor grows, it can create symptoms such as pain, swelling and organ dysfunction, leading the patient to seek medical care. Other tumors may be identified during routine medical examinations before the symptoms began to cause.
