Cancer or uncontrolled cell proliferation is considered the cause of death is widespread in the world today. There are many different types of cancer based on the affected tissue. Cancer can not be defined as a condition in which cells lose the ability to control their proliferation. The transformation of cancerous cells will be the result of a series of mutations and occur gradually.
Cancer Research studies show that the cause of cancer is mutated or pathological changes and suddenly in the genetic material – deoxyribonucleic acid (DNA). This does not mean that a single mutation can cause cancer, but the accumulation of mutations in the main part of the head of the genome in such conditions.
The results of the study showed that can cause some means of DNA, mutate how cigarette smoke, alcohol is thought that the chemicals found in red meat and various chemicals used in everyday life to cause cancer. Cancer is caused by mutations in the genetic material, they play an important role in the control of cell proliferation. regions concerned, known as oncogenic genome. It is estimated that there are about 200 types of cancer.
The mutations that cause normal cells to become cancer
The causes of cancer
The cause of cancer is the mutation of the cell. Mutations may be performed by a variety of ways. During cell division, although the probability of error is small, but it could still happen. If there is a mutation in a proto-oncogene (unchanged oncogenes), the initiation of cancer can result.
Several agents or substances classified as mutagens.There known mutations can cause more than 40,000 types of mutagens, organic gas and not mustard biological.Some, snuff, asbestos, UV and certain types of viruses, etc. oxidants mainly food, foods that can be high in fat and excess fat and intake of antioxidants found less cause cancer.
Cancer can occur in a variety of cell types and are named for the relevant cells. Among others:
the leukemia cancer among white blood cells
epithelial cancer sarcoma.
Myeloma nerves of cancerous tissues / neurons lining.
Hepatoma: cancerous liver cells.
Fibroids: cancer of connective tissue.
Lymphoma: a cancer in the lymph nodes.
In industrialized countries, 25% of cancer deaths. Based on statistics, an estimated 289,000 people in the UK suffer from cancer to cancer at the age of 67 years in 2001-2004 and an average age of mortality each year.The average age of 73 patients old was diagnosed. One in three people with cancer in the UK, and one of the major cancers are lung cancer, breast cancer, colon cancer and prostate cancer.
