Cancer is an umbrella term that covers a group of diseases sharing the common features but diseases vary by site of origin, tissue type, race, sex, and age. One of the main features is an uncontrollable growth of cells. These cells are capable of spreading to other parts of the body. This process is also known as invasion and metastasis.

Though cancer in kids is not the same as in adults, childhood cancer cells behave in the same way. They grow uncontrollably and can travel to new destinations in the body.

This video ‘Cancer: from a healthy cell to a cancer cell’ nicely explains this transformation.

This video ‘How does cancer spread through the body?’ gives a perspective on the ways cancer cells travel in the body.
