Localised therapy
Exact area - more specific
- surgery
- radiation therapy
Systemic therapy
Whole body - side effects are generalised
- chemotherapy
- hormonal therapy
- biological therapy
Radiation therapy
Allows healthy cells to regrow faster and manage the cancer
- uses radiation to destroy cancer cells (also damages normal cells, but cancer cells are more sensitive to its effects)
Radiation therapy implementation
Total dose of radiation is divided into smaller doses called fractions
One fraction is given each day over several days until the total dose is reached
Can be given externally or internally
Radiation therapy side effects
Fatigue
Skin reaction
Chemotherapy
Kills cells that are rapidly dividing (such as cancer cells) - also kills normal cells that are rapidly dividing; normal cells can repair the damage and recover
Chemotherapy implementation
usually given orally or intravenously in multiple courses for a set amount of time
Cycles allow time for the healthy cells to recover between treatments
Chemotherapy side effect
Fatigue Nausea Pain or soreness Changes to skin Diarrhoea Weight gain or loss Hair loss Changes to libido Emotional changes
