Q

What is cancer the result of

A

Damage to the genes that regulate mitosis and the cell Cycle. This leads to uncontrolled growth and division of cells.

As a consequence, a group of abnormal cells, called a tumour, develops and constantly expands in size

Q

Why do people loose hair with cancer

A

As cancer cells have a fast rate of division, they are damaged to a greater degree than normal cells. Those normal body cells such as hair producing cells, that divide rapidly are also vulnerable to damage
