    Cancer. Cancer is a group of diseases characterized by an uncontrolled growth of abnormal cells. If the spread of these abnormal cells is not controlled, cancer can cause death. Most cancers take the form of tumors, although not all tumors are cancers. A tumor is simply a mass of new tissue that serves no physiological purpose. It can be benign, like a wart, or malignant, like cancer. Benign tumors are made up of cells similar to the surrounding normal cells and are enclosed in a membrane that ...

    Introduction Purpose One of the many complications with cancer is that there are so many different types. Currently, there are 112 types of cancer, and there is an estimated 80 more types of cancer that are undiscovered. (United States Cancer Rates) That leads to as many different treatments as there are types of cancer. Figure 1, located after the Recommendations section, on page 8 displays the number of recorded cancer cases over the past 15 years. I propose to look at several types of treatme...

    Introduction to Cancer The individual unruly cell that has escaped the normal regulatory control mechanisms is the basic unit of cancer. Inside the nucleus is a substance called DNA, which contains genetic information for the body, organized in units called genes. These genes contain the complete plans for the body. They determine weather you have a blue or a green eye, weather you will have two or four legs, etc. They send out information that tells the cell what chemicals to make, as well as h...

    Cells inside of our body are under strict genetic control. If the genes controlling our cells become mutated, the cells can become disorganized by losing their function and dividing abnormally at less restraint than their neighboring normal cells. This activity causes the cells to fail to fully mature. Within our cells, we have regulatory proteins that perform such functions as correcting damaged genes. Other proteins indicate to a cell that division must cease so it can mature. A mutation of th...
