To give the details of the other types of DNA repair genes is beyond the scope of this article.

These are further classified into nucleotide excision repair genes and mismatch repair genes.

Whenever a cell is injured, several repair genes are called into play.

Malignancy may also be due to faulty DNA repair mechanisms.

When an injury is incited in the form of toxins and repeated inflammation, these cells become cancerous or malignant.

That is, cells that are normally programmed to die after a certain time do not die and instead persist.

Cancer is the result of a faulty apoptotic mechanism.

This physiological process is called apoptosis.

Cells in the human body have a limited lifespan and once they are done with their functions, they undergo programmed cell death.As a rule of thumb, poorly differentiated cells spread and invade tissues more rapidly by a process called metastasis. Poorly differentiated cells are also called undifferentiated cells.This means that they do not bear any resemblance to normal cells, whereas well-differentiated cancer cells bear some resemblance to normal cells.They are different from normal cells and in that they are poorly differentiated.It refers to the proliferation of an abnormal mass of cells. The medical term for any type of cancer is neoplasm.It is wrongly assumed that cancer is known as the 'crab disease' because of its firm grip on the life of a patient. In Greek, these words refer to a crab and more often than not, cancer cells have finger-like projections. Cancer has been rightly called "The Emperor of Maladies." Hippocrates was the first to use the terms carcinomas, and carcinoma.
