-Cancer-According to Cancer.org, cancer is the generic name for more than a hundred diseases. There are cancers that literally affect every part of the body. Cancer begins with uncontrolled growth of abnormal cells. Usually, if the cancer is detected early, it is treatable and the person has a good chance of surviving. Unfortunately, if cancer is left untreated for a prolonged period of time, the survival rate decreases. There are some types of abnormal cell growth that can be potentially more deadly than others. There are a surprising amount of different cancers to study. The chances of survival depend on the type, as well as how long the cancer has gone untreated. HOW CANCER FORMS To begin with, cancer begins to form when abnormal cells grow. Abnormal cells form when DNA is damaged. The fewer abnormal cells there are, the more treatable the cancer will be. In normal cells, damaged DNA is repaired or dies. In cancer cells, damaged DNA is not repaired or dies like normal cells. The damaged cell replicates. It's difficult to understand exactly why or how cancer begins to develop, but the most common causes may be related to sun exposure or smoking. Cancer cells usually form a tumor. Leukemia is a type of cancer in which no tumor forms. On the other hand, not all tumors are cancerous. There are benign and malignant tumors or masses. Benign tumors cannot spread to other organs in the body, but may be larger and put pressure on other organs. Benign tumors are not cancerous, but can still cause problems. Benign tumors can become malignant or cancerous after a while. Malignant tumors are those that are cancerous from the start. This...... middle of paper ...... emo that is given.

There are a surprising amount of different cancers to study. Bone cancer and lung cancer are very common these days. Chances of survival depend on the type, as well as how long it has been untreated..
