Cancer is a serious disease that affects almost 1 in 3 people in the United States. A person’s body contains trillions of cells. Normally, these cells die when they turn abnormal. But if these cells don’t die, they can crowd out healthy cells and cause the body to work harder to survive. This causes the body to produce more cancerous cells. It is important to find a treatment that will fight off the disease before it spreads to other parts of the body.
The symptoms of cancer develop when the body’s immune system releases chemicals that cause the illness. These chemicals are called cytokines, and they are similar to those released by the flu. When these chemicals accumulate, they form tumors, which can be hard to identify. Some cancers do not form tumors, however. These chemicals may cause pain, swelling, wasting, and other symptoms. Although cancer can affect anyone, it is more common in men than women.
The basic premise of cancer treatment is that it targets the abnormal cells that are causing the problem. In a cancer cell, the chromosomes change. For example, some cancer cells have double the number of chromosomes than normal cells. In addition, cancer cells use nutrients in different ways than healthy cells. This allows them to grow rapidly. Without these changes, the body’s immune system will be unable to fight the disease.
As cancer progresses, cells develop mutations that allow the cancer cells to escape the immune system and repair systems. In addition, these mutations make the cancer cells resistant to many body processes. The body’s immune system will attack these cancer cells, and they may even spread to other parts of the body. This is why cancer-causing genes accumulate slowly in people. These mutations can result in uncontrolled cell division. Further, the cells can migrate through the lymphatic system and blood vessels, and they can eventually spread to other parts of the body.
Fortunately, there are treatments available for cancer. The progression of cancer is not limited to a specific part of the body. Most cancers start in cells, which are the building blocks of the human body. This means that cancer can develop in many different places in the body. When this happens, the cells must break away from the original tumor and attach to an external wall of a vessel. Then they must pass through the wall of the vessel to reach a new organ.
The progression of cancer occurs in cells. These are the building blocks of the body. When the body forms new cells, it replaces old ones. When the extra cells remain, they form a tumor. These tumors can be benign or malignant, and they can invade other tissues and organs. The most common type of cancer is the breast. This type of cancer may be in the uterus, the bladder, the skin, or the lungs.
