1. The cell cycle is a series of events that take place in a cell leading to its division and duplication. It consists of interphase (G1, S, G2) and the mitotic phase (M phase), which includes mitosis and cytokinesis.
2. Cancer is a disease characterized by uncontrolled cell growth and division, often due to mutations in genes that regulate the cell cycle, such as tumor suppressor genes or oncogenes.
3. A tumor is an abnormal mass of tissue that results from excessive cell division; it can be benign (non-cancerous) or malignant (cancerous).
4. Apoptosis is programmed cell death, a natural process that eliminates damaged or unnecessary cells to maintain healthy tissue function.
5. Mutations are changes in the DNA sequence that can alter gene function; if they occur in genes controlling the cell cycle, they may lead to cancer.
6. Oncogenes are mutated versions of normal genes (proto-oncogenes) that promote cell division; when overactive, they can cause cells to divide uncontrollably.
7. Tumor suppressor genes are genes that help regulate cell division and prevent tumor formation; when mutated, they lose their ability to control cell growth.
8. Metastasis is the spread of cancer cells from the original (primary) tumor to other parts of the body, forming secondary tumors.
9. Chemotherapy uses drugs to kill rapidly dividing cells, including cancer cells, but it can also affect healthy cells that divide quickly, such as those in hair follicles or the digestive tract.
10. Radiation therapy uses high-energy particles or waves to damage the DNA of cancer cells, preventing them from dividing and growing.
11. Surgery involves physically removing the tumor and surrounding tissue to eliminate cancerous cells from the body.
12. Immunotherapy boosts the body’s own immune system to recognize and destroy cancer cells more effectively.
13. Targeted therapy uses drugs or other substances to specifically target molecules involved in cancer cell growth and survival, minimizing damage to normal cells.
14. Prevention strategies include avoiding tobacco, maintaining a healthy weight, eating a balanced diet, exercising regularly, limiting alcohol, protecting skin from UV radiation, and getting recommended screenings.
15. Early detection through regular screenings (e.g., mammograms, colonoscopies, Pap smears) can identify cancer before symptoms appear, increasing the chances of successful treatment.
16. Genetic testing can identify inherited mutations (e.g., BRCA1/BRCA2) that increase cancer risk, allowing for preventive measures or early interventions.
17. Lifestyle factors such as smoking, poor diet, physical inactivity, and chronic stress can contribute to cancer development by promoting inflammation, DNA damage, or hormonal imbalances.
18. Environmental factors like exposure to asbestos, radon, certain chemicals, air pollution, or ionizing radiation can damage DNA and increase cancer risk.
19. Viruses such as HPV, HBV, HCV, and EBV can cause chronic infections that lead to cellular changes and increase the risk of specific cancers.
20. Advances in research, including genomics, precision medicine, and immunotherapy, are improving cancer diagnosis, treatment, and outcomes, offering hope for more effective and personalized therapies.
