Tropical Anticancerous plants

  1. 1. University of Horticultural Sciences, BagalkotK. R. C. College of Horticulture, Arabhavi By, Rahul S. Phatak UHS11PGM140 Dept. of PMA

  3. 3. Cancer is generally considered to comprise morethan 100 diseases, each characterized by uncontrolledgrowth and spread of abnormal cells. (Watson, 2006)
  4. 4. Causes Internal factors Inherited mutation, hormones, immune condition and mutation that occur from metabolism. External factors Tobacco, Chemicals, Radiation and Infectious organisms (Baudino, 2004)
  5. 5. Genes Cancer
  6. 6. Types of cancerThere are Four types according to body tissue from which they arise1. Carcinoma : epithelial cells lining lung, liver, breast, prostate and pancreas2. Sarcoma: muscles, nerves and bones3. Lymphoma: cells in lymph glands4. Leukemia: blood forming tissue (Bagchi and Preuss, 2005)
  7. 7. Cancer globally…• Every year, diagnosed in 10 million people and account for 7.1 million deaths (12.5 % of global total)• Second to cardiovascular diseases• Global cancer rates could increase by 50% to 15 million by 2020• Due to smoking and adoption of unhealthy lifestyles• Brest cancer, colon cancer, prostate cancer, lung cancer and blood cancer are found major. (WHO, 2009)
  8. 8. How to cure..?SurgeryOldest known treatmentOnly if cancer has not metastasized
  9. 9. Radiation• Radiotherapy• By focusing high-energy rays on cancer cells• May cause side effects
  10. 10. ChemotherapyToxic drugs are neededFocus is to trigger the apoptotic programmeInhibition, blocking effect, anti progressionNatural, synthetic or both
