|
|
The DNA mutates and is passed along to the daughter cells. Division happens rapidly and cancer spreads.
|
|
|
The daughter cells do not divide
|
|
|
The parent cell does not divide
|
|
|
One daughter cell is bigger than the other daughter cell

Detailed explanation-1: -Cancer is the result of unchecked cell division caused by a breakdown of the mechanisms regulating the cell cycle. The loss of control begins with a change in the DNA sequence of a gene that codes for one of the regulatory molecules. Faulty instructions lead to a protein that does not function as it should.
Detailed explanation-2: -Gene mutations in cancer cells interfere with the normal instructions in a cell and can cause it to grow out of control or not die when it should. A cancer can continue to grow because cancer cells act differently than normal cells.
Detailed explanation-3: -As cancer cells divide, they acquire more DNA changes over time. Two cancer cells in the same tumor can have different DNA changes. In addition, every person with cancer has a unique combination of DNA changes in their cancer.
Detailed explanation-4: -DNA damage has been long recognized as causal factor for cancer development. When erroneous DNA repair leads to mutations or chromosomal aberrations affecting oncogenes and tumor suppressor genes, cells undergo malignant transformation resulting in cancerous growth.
Detailed explanation-5: -Cancer cells are cells gone wrong-in other words, they no longer respond to many of the signals that control cellular growth and death. Cancer cells originate within tissues and, as they grow and divide, they diverge ever further from normalcy.
