Study Notes
Oncology Week 12
-
Cancer's Pathophysiology: Cancer involves altered cell growth and damaged DNA in cells. Normal cells adhere, grow orderly, undergo controlled mitosis, and have a smaller nucleus-to-cytoplasm ratio. Cancer cells lack purpose, show disordered growth, divide continuously, and contain abnormal chromosomes. They have a larger nucleus-to-cytoplasm ratio and loose adherence. Oncogenes promote cell division.
-
Cancer Cell Development: Cancer cells arise from mutations that transform these cells, forming clones. These clones proliferate and acquire invasive characteristics, gaining access to lymph and blood vessels.
-
Benign Tumors: Benign tumors are typically harmless, not invasive, and remain contained. They resemble the original tissue and don't spread (metastasize) or cause death unless they obstruct critical functions due to their location.
-
Malignant Tumors: Malignant tumors are cancerous, invasive, often cause death, and spread to other regions of the body through metastasis. They are usually poorly differentiated, meaning they look very different from the original tissue and have significant growth and damage.
-
Hyperplasia and Metaplasia: Hyperplasia involves increased cell number (either normal or abnormal), while metaplasia involves a change from one cell type to another and can affect surrounding tissues. These changes can be indicators or even a part of cancerous processes.
Cancer Detection and Diagnosis
-
Diagnostic Tests: Testing for cancer involves assessments of various body parts/fluids, including imaging (mammograms, X-rays, CAT scans, MRIs, PET scans, ultrasounds, endoscopy) and lab work (tumour markers like PSA and CEA).
-
Staging and Grading: Staging categorizes the extent of cancer, its spread, and location (1-4), while grading signifies how abnormal the tumour cells appear, their resemblance to the original tissue.
Cancer Prevention and Epidemiology
-
Risk Factors: Smoking, exposure to carcinogens (UV radiation, chemicals), and genetic predispositions increase cancer risk. Hormonal factors, like synthetic estrogen, can also influence cancer development.
-
Prevention Strategies: Primarily, vaccines, avoiding carcinogens, managing lifestyle choices (diet, exercise, sun safety, etc), and early detection are crucial in cancer prevention.
-
Epidemiology: Cancer affects many people globally, disproportionately impacting older adults. The most common types differ between males and females. Early detection is vital.
Cancer Treatment and Outcomes
- Cancer Treatment: Therapies for cancer treatment may include surgery, radiation, chemotherapy, and various targeted biological therapies.
