Study Notes
Key Terms in Neoplasms
- Diagnosis: Complete knowledge determining the nature of a disease. Stands independently in medical contexts.
- Prognosis: Expected outcome or future knowledge regarding the course of a disease.
Neoplasm Characteristics
- Neoplasm Behavior: Can be categorized as malignant (cancerous) or benign (non-cancerous).
- Neoplasm Topography/Site of Origin: Refers to the specific anatomic site where the neoplasm originates, known as the primary site.
- Neoplasm Histology: Pertains to the type of tissue that composes the neoplasm.
- Neoplasm Cell Type: Involves describing the characteristics or appearance of the neoplastic cells.
Types of Neoplasms
- Benign Neoplasm: Non-invasive and does not metastasize. Examples include tumors, warts, moles, polyps, and fibroids. While often harmless, large benign neoplasms can compress surrounding organs, necessitating intervention.
- Malignant Neoplasms: Life-threatening growths commonly referred to as cancer. They can metastasize, spreading to vital organs and causing severe health issues.
Understanding Cancer
- Cancer: Broadly defined, cancer encompasses over 100 diseases characterized by uncontrolled cellular growth. Commonly associated with tumors, but can also refer to conditions like leukemia, which does not produce tumors.
- Incidence: The American Cancer Society estimates that half of all men and one-third of all women will develop cancer in their lifetimes.
- Common Cancer Sites: Prostate (men), breast (women), lung, and colorectal regions are most frequently affected. In children, leukemia and medulloblastoma are prevalent.
Diagnosis and Treatment
- Diagnostic Approaches: Physicians use screening examinations, blood tests, biopsies, and imaging techniques like CT, MRI, and PET for cancer diagnosis.
- Cancer Treatment: Treatment aims to destroy cancer cells, often resulting in side effects as healthy cells can also be affected. Patient decisions regarding treatment options are intensely personal.
- Carcinoma (CA): This type of malignant tumor arises from epithelial cells, which line organs and cavities. True carcinomas are restricted to tissues containing epithelial components.
Carcinoma In Situ
- Carcinoma In Situ: Refers to localized cancer cells that have not yet invaded surrounding tissues, representing an early stage of malignancy.
