What is the difference between a malignant tumor and a metastasis?

Is a malignant tumor the same as cancer?

Malignant Tumor (Cancer)

Malignant tumors are cancerous growths. They are often resistant to treatment, may spread to other parts of the body and they sometimes recur after they were removed.

Thus, characteristics of malignant neoplasms include:

  • More rapid increase in size.
  • Less differentiation (or lack of differentiation, called anaplasia)
  • Tendency to invade surrounding tissues.
  • Ability to metastasize to distant tissues.
