Here's why:
* T cells are a type of lymphocyte, which are white blood cells that play a key role in the immune system.
* Thymus is a gland in the chest where T cells mature and develop their ability to recognize and attack specific targets.
* Cancer cells are abnormal cells that can grow uncontrollably and invade other tissues. Some T cells, particularly cytotoxic T cells, are specialized to recognize and kill cancer cells.
Therefore, T cells formed in the thymus are the white blood cells responsible for attacking cancer cells.
