What is Abnormal Cell Division?

We are all acquainted with the terms, ‘Tumor’, ‘Cancer‘, etc. These are the result of abnormal cell division. Abnormal cell division refers to any disease characterized by uncontrolled cell division that produces abnormal tumor or neoplasm. In mitosis one cell divides into two, two to four and in this way the number of cell increases. But there is a regularity in this process. If under any circumstances this regularity is lost, the cell divides abnormally. As a result, a tumor is formed.

When a chromosome is abnormal, it can cause health problems in the body. Abnormal chromosomes most often happen as a result of an error during cell division. Chromosome abnormalities often happen due to one or more of these:

  • Errors during dividing of sex cells (meiosis)
  • Errors during dividing of other cells (mitosis)
  • Substances that cause birth defects (teratogens)

Abnormal Cell Division

The cancer cell is also a product of uncontrolled abnormal cell division. It has been found in the experiment that various type of Papillomavirus helps to produce cancer cell. Two genes named E6 and El of this virus (Papilloma) produce some chemicals, which displace two protein molecules responsible for controlling the cell division. As a result, control over cell division is lost and thus a tumor is produced. Sometimes these two genes may be united with the genes of the host cell and stop the action of protein to control the cell division and thus there develop cancer cell or Cancer.

Cancer is a fatal disease. Every year five to six hundred thousand patients die only because of various forms of cancer. Cancer generates in liver, lunge, brain, breast, and skin i.e. almost all the organs of the body. No effective medicine has yet been discovered to prevent this disease.
