Detailed explanation-1: -Cancer cells are cells gone wrong-in other words, they no longer respond to many of the signals that control cellular growth and death. Cancer cells originate within tissues and, as they grow and divide, they diverge ever further from normalcy.

Detailed explanation-2: -Cancer cells can break away from the original tumor and travel through the blood or lymph system to distant locations in the body, where they exit the vessels to form additional tumors. This is called metastasis. Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues.

Detailed explanation-3: -Cancer: Uncontrolled Cell Growth Cancer is a disorder in which cells divide uncontrollably, forming a mass of cells called a tumor. Cancers are caused by defects in genes that regulate cell growth.

Detailed explanation-4: -Cancer is a disorder in which some cells have lost the ability to control their.

Detailed explanation-5: -Cancer cells ignore signals from other cells Cells send chemical signals to each other all the time. Normal cells obey signals that tell them when they have reached their limit and will cause damage if they grow any further. But something in cancer cells stops the normal signalling system from working.
