Death of a Tumor Essay -- Biology Cancer

Cell BackgroundAnimal cellular phones argon eucaryotic and have a very complex structure. A eukaryotic cell is tranquil of many an(prenominal) tissue layer-enclosed organelles. Organelles are compartments that perform different functions deep down the cell. An organelle called the nucleus contains the genetic material, or DNA, and is the most vital organelle of the cell because it is responsible for carrying the genes that reconcile up the body. A cells membrane is composed of two layers that regulate the flow of materials in and out of the cell. Along the membrane are some(prenominal) kinds of receptor proteins that detect foreign materials. A cell replicates by a serve up called mitosis. In this process the chromosomes pair up and when the cell discriminates and each cell is genetically identical. Any mistakes in this process hindquarters lead to cancer. If somewhere along the line, the normal regulation of mitosis is befuddled and the cell divides continuously and o ut of control. This is how tumors are created. There are many reasons for the mitotic cycle to break such as the loss of certain checkpoints, which make sure the cell is dividing normally. Without these checkpoints in the cycle of mitosis, the cell does not divide normally, and this usually leads to the growth of tumors. Tumor Prevention There are several ways to prevent cancer, but some of the time cancer is a genetic defect that cannot be prevented. Overexposure to sunlight or tanning salons whitethorn cause skin cancer. Clothing and sunscreen protects the skin from the sun and can decrease the chances of skin cancer. To decrease the risk of developing cancer, one should not smoke. Smoking increases the risk of developing cancer of the lung, mouth, throat, esophagus, panc... ...s showed that Raf-1 had indeed prevented angiogenesis from occurring by devising apoptosis successful in destroying the tumor. TUNNEL had shown that the nearby dead descent vessels had self- destructed l eaving behind signs of apoptosis in tumor cells. This supported what the scientists had substantiate that each telephone circuit vessel has the ability to support 50-100 tumor cells. When the blood vessel dies, so do the tumor cells, thus crumbling into a concentrical ring. Resources & Links1Cancer Research UK. Catrin Pritchard, Ed.
