Study Notes
Cancer Concepts
- Neoplasia: uncontrolled cell growth that does not follow physiologic demand
- Cancer: a disease process where cells proliferate abnormally, ignoring growth-regulating signals in the environment
- Benign: not cancerous; benign tumors may grow but are unable to spread to other areas
- Malignant: having cells or processes characteristic of cancer
Types of Cancer
- Identified by tissue affected, speed of cell growth, cell appearance, and location
- Examples:
- Carcinoma: originates in epithelial tissue (e.g., lungs, stomach, liver)
- Sarcoma: originates in mesenchymal tissues (e.g., bone, muscle, connective tissues)
- Leukemia: originates in blood-forming tissues
- Lymphoma: originates in immune system cells
- Melanoma: originates in skin cells
- Benign tumors:
- Fibroma: affects connective tissue
- Lipoma: affects fat tissue
Benign vs. Malignant
- Benign:
- Slow growth rate
- Cells are typical of the tissue of origin
- Minor tissue damage
- Remains localized
- Seldom recurs after surgical removal
- Prognosis: not injurious
- Malignant:
- Rapid growth with infiltration
- Cells are atypical of tissue origin
- Causes necrosis and ulceration of tissue
- Spreads to other body parts (metastasis)
- Can recur after removal
- Prognosis: potentially fatal if uncontrolled
Malignant Process
- Cell proliferation
- Cell characteristics:
- Presence of tumor-specific antigens
- Altered shape, structure, and metabolism
- Metastasis:
- Spreads through lymphatic or hematogenous routes
- Becomes more heterogeneous, making treatment more difficult
Carcinogenic Agents and Factors
- Viruses and bacteria
- Physical factors
- Chemical agents
- Genetic and familial factors
- Diet
- Hormones
- Role of the immune system
Warning Signals
- Change in bowel or bladder habits
- A sore that does not heal
- Unusual bleeding or discharge
- Thickening or lump in breast or other tissue
- Indigestion or swallowing difficulties
- Obvious change in wart or mole
- Nagging cough or hoarseness
Prevention and Treatment
- Primary prevention: reducing cancer risk in healthy people
- Secondary prevention: detection and screening for early diagnosis and intervention
- Cancer treatment goals:
- Cure
- Control
- Palliation
- Cancer management:
- Surgery
- Radiation therapy
- Chemotherapy
- Bone Marrow Transplantation (BMT)
Nursing Interventions
- Prevention of infection
- Managing stomatitis
- Maintaining tissue integrity
- Protecting skin and oral mucosa
- Managing pain
- Decreasing fatigue
- Improving body image and self-esteem
- Assisting in the grieving process
- Teaching patients self-care
- Assisting with cancer rehabilitation
- Hospice and palliative care
