Care of Clients with Cellular Aberrations: Evolution of Cancer Cells

Cancer refers to a disease whereby cells mutate into abnormal cells that proliferate abnormally.  Neoplasia refers to an abnormal cell growth or tumor.  A tumor is a mass of new tissue functioning independently and serving no useful purpose

  • Benign neoplasms are slow-growing, localized, and encapsulated non-malignant growths with well-defined borders.
  • Malignant neoplasms are aggressive growths that invade and destroy surrounding tissue and which can lead to death unless interventions are taken.

Invasion occurs when cancer cells infiltrate adjacent tissues surrounding the neoplasm

Metastasis occurs when malignant cells travel through the blood or lymph system and invade other tissues and organs to form a secondary tumor.
