The last 50 years has seen a better understanding of the causes and treatments of cancer. Hence, the stigma, early detection and technology has improved the prognosis of cancer patients to an unprecedented level.
Cancer is a term used to describe a large group of diseases that are characterized by a cellular malfunction. Healthy cells are programmed to “know what to do and when to do it”.

This neoplasmic mass often forms a clumping of cells known as a tumor.
