The Silent Killer Cancer is one of the leading causes of death in the world. It is truly the silent killer. If you don’t find it in time‚ the doctors won’t be able to stop it‚ and you will probably die. Cancer is a wide range of diseases that develop when the DNA of a cell become’s damaged or changed‚ producing mutations that warp normal cell growth and division. Cancer cells do not die when regular cells would and new cells continue form. The extra cells may form tumours. Benign tumours that aren’t

to put cancers in the right perspective. By way of definition‚ a cancer is a malignant tumor or swelling composed of abnormal cells capable of undergoing uncontrolled proliferation. Many erroneously hold the view that every swelling or lump is cancer. However‚ this is not so. Unlike benign swellings‚ cancerous cells generally have the tendency to invade surrounding tissues and sometimes metastasize (break off and spread) to distant body tissues via the bloodstream or lymphatic system. Cancers result

technology? More explicitly can cell phones cause cancer? This question is the basis of this review. The researcher has compiled articles that cover this topic from diverse scholarly sources‚ and diverse countries. It is undeniable that cellular technology has become main stream. "It was estimated that there were 92 million cell phone users in the US‚ a number growing by one million every month." (Frumkin‚ Jacobson‚ Gansler & Thun 2001). The arrival and widespread use of cell phones has peaked interest

Cell division in animals: mitosis‚ cytokinesis‚ and the cell cycle. Cell division in animals is a two-step process involving mitosis and cytokinesis and is set up by interphase. Interphase is a growth period for the cell. In the nucleus the chromosomes are duplicated but are not yet distinguishable because they are still a form of chromatin. There is also a nucleoli‚ one or more‚ present producing ribosomes that are sent to the cytoplasm. Mitosis is the division of the nucleus and multiplication

Cell Phones Might Cause Cancer I remember the first time my grandfather told me he had cancer. My assumption was that it was all health related. Yet I learned that it was also caused by the usage of electronic devices. I was shocked and surprised of this news. Will this start to affect the future of my generation? It seems like everyone is on some type of electronic device everywhere you look.. Cell phones first became widely available in the United States in the 1990s. Ever since then the use

INTRODUCTION A major obstacle in the successful treatment of cancer is the development of resistance mechanisms to drug treatment. Various cellular changes that have been implicated in the development of drug resistance in cancer cells include: the increased expressions of P-glycoprotein (a multidrug transport protein) and multidrug resistance-associated protein (MRP-1); increased levels of the cellular detoxification protein‚ glutathione; and changes in the expression of apoptosis associated

Cell Biology Oct.3/14 Cell Cycle part 3: Apoptosis 2 Main ways cells will die: apoptosis is regulated‚ nacrosis is an “explosion” Apoptosis Part of controling number of cells. Importance in balance.“Programmed cell death” – important because if the cell isn’t intact you don’t want cell to divide and keep mutations going‚ to avoid inflammatory response (caused by cells that exploded/necrosis).. ect. Necrosis is triggered by something unplanned‚ leading to decrease ATP‚ pumps‚ atpase activity

How Cancer Cells Differ From Normal‚ Healthy Cells Cancer cells are very different from healthy cells. Healthy cells grow and divide like they are suppose to‚ whereas cancer cells do not grow and divide in a healthy way. So instead of acting in healthy ways as the body needs to function the cells begin to grow in unhealthy ways and affect all other cells. (http://biology.about.com/od/cellbiology/ss/normal-cells-cancer-cells.htm) There are many things that can happen to us that can cause our healthy

Cancer is the number one disease in the world. But what exactly is cancer? What most people know about cancer is that it can be deadly and it’s mostly related to someone losing their hair. But‚ beyond that cancer is a tricky subject. Why? Because no one really knows how cancer is created. Could it be possible‚ that cancer cells have the same characteristics as normal stem cells and that is why they grow and invade rapidly? And if so can scientist and doctors use this information to find a permanent
