Study Notes
Cancer Overview
- Cancer is a serious, complex disease affecting humans throughout history
- Cancer incidence rates are difficult to compare historically due to differing diagnoses
- Cancer is not contagious; it results from faulty genes within cells
- Tumors are clusters of cells; malignant tumors spread to other body parts, benign tumors remain contained
- Hippocrates recognized distinction between benign and malignant cancers, coining the term karkinos (crab), translating to carcinoma
History of Cancer
- Ancient Egyptians and Peruvians documented breast and bone tumors
- Cancer was not well understood for centuries, making historical incidence difficult to measure
- Hippocrates, the Greek philosopher, recognized different types of tumors, noticing swollen blood vessels around malignant ones
- The term "carcinoma" derives from Hippocrates' observation of crab-like tumor growth
What is Cancer?
- Cells divide for growth, repair and replacement
- Cellular reproduction is regulated by genes
- Cancer originates from damaged genes that affect cellular division control
- Damaged genes can lead to uncontrolled cell growth, resulting in tumors
Causes of Cancer
- Environmental factors may be linked to higher cancer rates in certain areas, such as polluted urban environments
- Pollutants and radiation act as mutagens, substances damaging DNA
- Cancer-causing alterations can be introduced through few gene mutations in cells
- Two types of genes regulate cell division include oncogenes and tumor suppressor genes
- Oncogenes act like an accelerator, promoting cell division while tumour suppressors act as brakes, slowing cell division
Types of Cancer
- Cancer can affect many organs and can present in various forms (basal/squamous cell skin cancer, breast cancer, lung cancer, prostate cancer, colon cancer)
- Specific cancers vary in treatable outcomes
Important Figures
- Hippocrates - Ancient Greek philosopher who identified the differences in tumors and recognized the importance of blood vessel swelling around malignant tumors
