Cancer in short is nothin but a class of diseases which are caused due to abnoral growth of cell. There are more than 100 types of Cancers which are classified according to the type of cell which it attacks. When the cells in the body divide uncontrollably, they lead to formation of Tumors i.e. mass of tissues. Tumors releases hormones which alters body functions and interferes with digestive, circulatory, nervous systems.
When does an Tumor occur ?
1. Invasion - a cancerous cell manages to move throughout the body using the blood or lymph systems, destroying healthy tissue in a process called Invasion.
2. Angiogenesisa - the cancerous cell manages to divide and grow, making new blood vessels to feed itself is a process called Angiogenesisa.
Cancer is caused when cells that grow uncontrollably and do not die. Generally, cells in a normal body grow, divide and die. When the above said process breaks down, Cancer begins. Cancer cells do not die instead they continue to grow and divide. When this continues leads to a accumulation of abnormal cells that grows out of control.
Cancer causes about 13% of all deaths in the world.
