Description
Cancer
Cancer cells are descendants of a single normal cell in which genetic errors, or mutations, have occurred. In cells, genetic errors occur in the basic building blocks of DNA called genes. These errors may occur spontaneously or randomly when cells divide, or they may present themselves as a result of exposure to environmental toxins (carcinogens).
Most of the time, your body will react and correct the problem without you ever knowing. Cells will detect and correct errors, or other genes will become activated and cause the mutated cell to die. The immune system will also recognize damage cells and kill them before tumors can form and cause problems. Because of all these factors, cancers are not thought to be the result of a single event. A combination of negative events and missed opportunities are required for cancers to form.
Lymphoma
Lymphoma is a type of cancer that can appear when an error occurs in the way a lymphocyte is produced. It encompasses a variety of cancers specific to the lymphatic system, an important network of glands and vessels which make up the body's immune system, our main line of defense against disease.
