How are cancer cells different from normal cells?

The cancer cells are simply the overactive form of a normal cell, every normal cell has a cell cycle like a time of growth and division when the cells do not identify the stoppage point and actively continue growth with an increase in size and number then it results in cancer cells.

The cancer cells are mainly similar to that of normal cells, the cancer cells are distinguished as larger in size than normal cells and seen in chaotic collection. We can understand the difference between cancer cells and normal cells more scientifically by studying the normal cell cycle first.

The cell cycle is a whole life growth of a new cell as the cell cycle has different phases Growth 1 phase (G1 phase), Synthesis phase (S phase), and Growth phase (G2 phase). The start of cell division is from the G1 phase in this the normal fully developed cell goes into the cell cycle that is G1 phase, and in the G1 phase cell grows itself. the next phase is the S phase in which the cells duplicate their DNA material or we can say new DNA synthesis.

In the G2 phase, the cell prepares itself to divide or split itself and genetic material to form a new cell. if the cell divides and forms two daughter cells called mitosis (two diploid genetically identical daughter cells). If the cell division results in 4 haploid daughter cells then called meiosis.

These new cells now do their work and remain in position till there is a need for new cells, the impulse of the need for new cells induces the generation of the cell cycle. Every cell has a cell cycle and death (apoptosis). When the normal cell cannot identify its death and continues to increase in the generation of new cells results in cancerous cells. The cancer cell grows faster and has uncontrolled growth than the normal cell,

The use of energy (ATP) of a cancer cell is more than that of a normal cell. The normal cells remain in their location, but the cancer cells spread to different locations in the body. normal cells reach maturity but cancerous cells do not reach maturity. the normal cells do assigned work or tasks, but the cancerous cell tasks are not defined. the normal cell blood vessels grow and feed for normal growth and repair but the cancerous cell blood vessels grow regardless constantly feeding and suppling to tumor.

the cancerous cells do not respond to the communication signals of other cells as normal cells do. the normal cell responds to signals from nearby cells that inform the size of the cell as reaches the boundaries, as the normal cell stops growing itself when reaches to boundary. the cancerous cell growth compresses other cells and disturbs the function of normal cells.

The nucleus of a cancer cell looks larger and darker than a normal cell, the cancerous cell nucleus is darker because it contains a large amount of excess DNA. some studies have shown that cancerous cell contains an abnormal number of chromosomes and are disorganized in arrangement. Normal cells when get damaged then lymphocytes engulf them and digest normal cells by identification of damaged cells, but cancerous cells are not detected by lymphocytes and remain for a long time in the body by continuously growing and forming a condensed bundle of cells or tumors.

Cancer cells are different from normal cells as our body cell DNA carries genes or protein signals that give a signal to the cell to grow and mature itself, divide when this gene coding or protein signal has some defect that the cell does not know how to behave and do not understand the limit of growth maturation and division.
