​Important Facts About Colon Cancer

Cancer starts with cells, the blocks which build into tissues. They make up the body's organs. Typically, cells will grow and than divide to create new cells when they are needed by the body. Once cells grow old, they will die, and new ones take their position. Occasionally, this process goes another way. New cells get created when they are not needed, and old ones stay alive. These extra ones may grow into a tumour. They can be malignant or benign.

Important Facts About Colon Cancer

Benign tumors can not be called cancer:

  • Are rarely threating the life
  • Tend not to grow back and can be safely removed.
  • Don't invade into the tissues.
  • Their cells don't spread to the body.

Malignant tumors can be called cancer:

  • Are usually more serious and life threatening.
  • Can be removed yet occasionally grow again.
  • Can invade and damage some organs and tissues.
  • Cells can spread to other body organs. They spread by entering the bloodstream or lymphatic system. The cancer cells build new tumours that can damage body organs. This spread is typically called metastasis.

In many cases are present in certain lymph nodes, when colorectal cancer spreads out of the colon or rectum. It can spread to other organs, if these cells have reached these nodes. Colorectal cancer cells sometimes spread to the liver.

When it spreads to another section of the body from its first location, that new tumor has exactly the same name as the first tumour and the same type of non-normal cells. As an example, if it spreads to the liver, these cells are really the colorectal cells. It is metastatic colorectal cancer, not the liver cancer. Doctors call the new tumor or metastatic or "distant" disease.
