The lymphoid stem cell develops into a lymphoblast cell and then into one of three types of lymphocytes (white blood cells):


There are three ways that cancer spreads in the body.


When cancer cells spread outside the blood, a solid tumor may form. This process is called metastasis. The three ways that cancer cells spread in the body are:

  • Through the blood. Cancer cells travel through the blood, invade solid tissues in the body, such as the brain or heart, and form a solid tumor.
  • Through the lymph system. Cancer cells invade the lymph system, travel through the lymph vessels, and form a solid tumor in other parts of the body.
  • Through solid tissue. Cancer cells that have formed a solid tumor spread to tissues in the surrounding area.
