Study Notes
Introduction to Oncology
- Oncology is the branch of medicine focused on cancer prevention, diagnosis, and treatment.
- It incorporates various medical specialities, including surgery, radiation therapy, chemotherapy, and targeted therapies.
- Oncology continually advances with new discoveries and improvements in understanding cancer biology and treatment strategies.
Types of Cancer
- Cancers are categorized by the tissue of origin.
- Examples include carcinomas (epithelial tissues), sarcomas (connective tissues), leukemias (blood cells), and lymphomas (lymphatic system).
- Each cancer type has unique characteristics, including growth patterns, spread, and response to treatment.
Cancer Development
- Cancer results from uncontrolled cell growth and division.
- Mutations in genes controlling cell growth and death drive this uncontrolled growth.
- Factors like genetic predisposition, environmental exposures, and lifestyle choices contribute to cancer development.
- These factors accumulate genetic damage, transforming cells.
Cancer Diagnosis
- Diagnosis uses clinical evaluation, imaging (X-rays, CT scans, MRI), and laboratory tests (blood tests, biopsies).
- Biopsies examine tissue samples to identify cancerous cells and determine specific cancer type and severity.
- Staging assesses the cancer's extent and spread.
Cancer Treatment
- Treatment varies by cancer type, stage, location, and patient health.
- Surgery removes tumors or affected tissues.
- Radiation therapy targets and destroys cancer cells with high-energy rays.
- Chemotherapy uses drugs to halt cancer cell growth and division.
- Targeted therapies precisely attack cancer cells without harming healthy cells.
- Immunotherapy harnesses the body's immune system to fight cancer.
Cancer Prognosis and Outcomes
- Cancer prognosis varies greatly depending on cancer type, diagnosis stage, and treatment response.
- Prognosis factors include patient age, overall health, and lifestyle.
- Research focuses on improving diagnostic techniques, developing more effective therapies, and better understanding cancer biology to enable personalized treatments and improved outcomes.
Cancer Prevention
- Reducing cancer risk factors is vital.
- Lifestyle significantly impacts cancer risk.
- Avoiding tobacco, maintaining a healthy weight, balanced diet, regular exercise, and minimizing carcinogen exposure are key preventive measures.
- Early detection through screenings is crucial in lowering mortality.
Cancer Research
- Oncology research is continually advancing.
- Current research focuses on the underlying mechanisms of cancer and developing more effective, less toxic targeted therapies.
- Personalized medicine tailors treatments to individual patients for optimized outcomes.
