Characteristics of Cancer cells: How Cancer cells are different from normal cells?

Cancer: It is a group of disorders resulting from a loss of cell cycle control due to multiple mutational events.
 Or It is a group of diseases characterized by uncontrolled cell growth and division.
Characteristics of Cancer cells: How Cancer cells are different from normal cells?

Characteristics of cancer cells:
  • Uncontrolled cell growth and division. (Cells becomes immortal)
  • Cells become independent from normal cellular controls that limits growth and division.
Normal cell vs Cancer cell
  • It becomes invasive or capable of spreading from one tissues to other called as metastasis.

Other characters:

  • Density independent growth of cells: Normal cells stop division when it touches the boundaries of other cells, termed as ‘contact inhibition’. Cancer cells loss this property and form layers one above the other.
  • Altered morphology: The nucleus of the cells become irregular and the number of lysosomes increase in cancer cells.

  • Difference between nomal cell and cancer cell
    • Uncontrolled division even in the absence of growth stimulators (immortal).
    • Presence of telomerase in cancer cells.
    • Cells show aneuploids or variation in chromosome number.
    • Cancer cell induces vascularization to support their growth.
    • Induce angiogenesis (blood vessel formation).
    Cancer is a curable disease with proper treatment, faith, love, care and support,…………. our immune system is one of the best known defense systems in the entire universe.
