TREATING CANCEROUS CELLS HIV/AIDS HEPATITIS C Frank Lake & Immanuel Park

What is cancer?

Cancer  Cancer is uncontrolled cell growth 7  Damage or change of genetic material of cells by external or internal factors 7  Cells do not die but continue to multiple until a concentration of cancer cells develop 7

Treating Cancerous Cells  Four standard treatments: surgery, chemotherapy, radiation therapy, and biologic therapy 6  Oncologist (cancer specialist) will recommend best treatment based general health, age, severity, type of cancer, etc…

 Surgery: remove tumour or cancerous tissue 6  Chemotherapy: usage of drugs to eliminate rapidly multiplying cells throughout the entire body (including hair follicle cells) 6  Radiation Therapy: Certain forms of energy used to shrink tumours and eliminate cancer cells by damaging cancer cells DNA, withholding it from multiplying 6  Biologic Therapy: Drugs use to target cancer cells. Varied methods include blocking biological processes of tumours that allow tumours to grow or cut off blood supply to the tumour killing it by means of starvation 6

What is HIV/AIDS?

HIV & AIDS  HIV (Human Immunodeficiency Virus)  AIDS (Acquired Immune Deficiency Syndrome)  HIV virus’ usually zeros in on “T” cells (the brains behind specialized cells that fight off invading germs) 8  Virus uses newly obtained cells to multiply  HIV has four stages 4  Weakens immune system  Eventually leads to and causes AIDS

Treating HIV/AIDS  No cure 2 5  Most common treatment known as antiretroviral treatment 5  Drug taken daily to hold off HIV at a low level 4  Stops weakening of immune system  Allows body to recover from any damage HIV may have caused  Prolongs life from illness

Treating HIV/AIDS  Combination therapy  Taking two or more antiretroviral pills  Reduces rate at which HIV can become resistant 8  Further prolongs life from illness

What is Hepatitis C?

Hepatitis C  Single strand of RNA virus enclosed in a fatty cell 9  Affects the liver  6 types of hepatitis C (genotype 1, genotype 2, etc...)  Estimated 242,500 people are infected with the virus 1

Contracting Hep - C 3  Through blood-to-blood contact 3  Sharing shaving kits, needles 3  Contaminated ice cubes  Sexual intercourse 3  Vertical transmission (born with it) 9  Breastfeeding 3

Hep – C: what it does  Destroy liver 1  Liver Cancer, or cirrhosis 1  Enzymes will not be as effective in their jobs  Slow chemical reactions which occur in the liver

Treatment of Hep-C  No cure – go into recession  Medication (injections and pill) Interferon Alpha - injection Ribavirin - pill  24 or 48 weeks  Kills RNA virus, once virus is destroyed, cells repair 1  Never fully cured, more medication

Non-Medical Treatment  Dealing with depression  Drinking

Liver Enzymes “ aspartate aminotransferase (AST or SGOT) and alanine aminotransferase (ALT or SGPT). Together they are known as transaminases. Alkaline phosphatase (AP) and gamma-glutamyl transferase (GGT) – are known as cholestatic liver enzymes.”  "Liver Enzymes." Liver Enzymes. Web. 09 Sept
