Cancer
A lot of people have known someone who has died of cancer. But what is cancer? Cancer is a disease. However, cancer can't be spotted and treated immediately like any other disease. This is because, well, cancer isn't just any other disease. It's a group of diseases that involve abnormal cell growths. So there isn't just one cancer like there's only one malaria or chickenpox. Cancer comes in over 100 different forms. But how does it work? It occurs at the cellular level in any part of the body, mostly in older people, but children have also been diagnosed with cancer as well. It involves normal cells growing out of control or too rapid, they consume large amounts of the body's energy, and produce toxic substances. The excess tissue the that develops from cancerous cells is called a tumor (sometimes referred to as neuroplasm). Sometimes a tumor may be harmless, known as a benign tumor, and at other times a malignant tumor. A malignant tumor has the power to metastasize, or spread to other parts of the body. The benign tumor doesn't metastasize, however, may become disfiguring or interfere with bodily functions that require surgical removal. There are two main types of cancer, the carcinomas and the sarcomas. The diffe
But having some risk factors means a person may be more likely to have the cancer at some point. The problem with the chemotherapy is that it poisons both the cancer cells and the healthy normal cells. rence is that a carcinoma, which is the most common, starts in the glands and surface tissues of the body( such as skin, colon, breast, and prostrate) , and the sarcoma that starts in connective tissue (such as bones and muscles) . The T-cells of a person's immune system would be thought to attack a cancer cell. Is it possible to spot out the symptoms immediately? The problem is that cancer doesn't just produce one symptom and may be any symptom or sign (A symptom is an indication of disease or illness felt by a person, where as a sign is an observation made by a doctor. So chemotherapy is pretty much a gamble. Carcinogens (substances that cause cancer) are associated with 60-90% of all human cancers. But once the cancer has grown in size and spread, the treatment becomes increasingly difficult and the chance of the person surviving declines. As an example, a brain cancer may cause pains at an early stage, whereas pancreatic cancer does not grow large enough to be felt outside the body, but in the later stages may grow to push on nearby nerves, causing pain. But say a person thinks they may have cancer. Meaning, that it runs in the family. People must be aware of certain risk factors of cancer. They start feeling strange, or see abnormalities on their body. Some carcinogens can be found in cigarettes and in ultraviolet rays in the sun.
