Cancer is used to denote the group of diseases that affect various parts of the body. It is caused by uncontrolled cell division and their spreading to other parts of the body. Since the disease revolves around cells, which are basic human body units, it can start from anywhere.<\/p>\n
Formation of Cancer<\/strong><\/p>\n Every cell has a specific function to perform and a period until it has to complete the process. After some time, the cell is instructed to die and give way to new and improved cells. Sometimes, the order is broken, and the message may not reach the cells. Then the cells will keep multiplying without dying, creating bumps on the body known as tumors. These tumors can be cancerous and non-cancerous.<\/p>\n Cancerous tumors spread from the infected organ to other parts of the body and form tumors there. These tumors are called malignant tumors. In contrast, benign tumors are those tumors that are non-cancerous. They will not grow back after removing them through surgery, unlike malignant tumors. However, some benign tumors cannot be removed through surgeries like the benign tumor of the brain.<\/p>\n There are over hundreds of cancers, each named after the tissue or organ they affect.<\/p>\n However, there are a few broad categories into which cancers are classified: carcinoma, which are cancers formed on the inner and outer surface of the body; sarcoma, which targets the soft tissues and bones; leukemia; lymphoma; multiple myeloma; melanoma; and brain and spinal tumors.<\/p>\n
