Study Notes

Cancer and Neoplasia

  • A new abnormal growth that does not respond to normal growth-control mechanisms is referred to as a neoplasm.

Theories of Neoplastic Transformation

  • The mutation theory postulates that an accumulation of mutations in the cell results in the transformation to a neoplastic state.

Leukemia

  • The most frequently occurring type of cancer in children is acute lymphoblastic leukemia.
  • Acute lymphoblastic leukemia is characterized by the malignant proliferation of lymphoblasts, leading to a decline in the production of RBCs and platelets.

Viral Theory of Cancer

  • The viral theory of cancer suggests that oncogenic viruses have the ability to change the structure of DNA or RNA in cells.

Types of Neoplastic Growth

  • Malignant neoplastic growth is characterized by unlimited growth and is cancerous.
  • Acute lymphoblastic leukemia affects lymphocytes and is the most frequently occurring type of cancer in children.
