What is cancer?
This is a condition in which changes in the activities of the cell lead to the continuous and uncontrollable growth and division of the cells in the different areas of the body. In some cases, the growth of these cells is visible and are called tumors while in cases of leukemia (cancer of the bone marrow), the cell divisions are not visible. There are different forms of cancer such as ovarian, skin, lung, breast cancer, and others.
