Regular exercise every day (30 minutes)
How do we screen for Cervical cancer, CRC and breast cancer?
Smear tests
Faecal occult blood the most commonly used test
- 16% reduction in CRC mortality
Mammography
How do we screen for prostate cancer?
PSA blood test
How do we screen for lung cancer?
MR / CT scanning
Breath test
How do we protect families with a history of CRC & familial adenomatous polyposis coli (FAP)?
Screen families for APC mutations
- regular colonoscopy
- offer panprotocolectomy when adenomas found

Prophylactic tamoxifen
What are the therapeutic ‘treatment options’?
Local or regional treatment
- surgery - radiotherapy - ablation (freezing, radio-frequency, etc) - isolated limb perfusion
Systemic treatment
- hormonal therapy - chemotherapy - immunotherapy - whole body irradiation (for BMT)
What are the principles of staging?
Looking WHERE it is and examining it using radiological techniques (CT , MRI, USS, PET etc)
Determining WHAT kind of cancer it is using pathology / cytology
To determine Classification, risk factors etc
Genomics likely to play a role in the future

Can treat inoperable lesions (– treat things you can’t remove)
Can make surgery become possible
Can maintain function and or appearance
Important role in palliation - improving someones symptoms
What are the 5 R’s of radiobiology?
Radiosensitivity Repair Re-population Re-oxygenation Re-assortment
Define radiosensitivity
How sensitive the tumour is to the treatment
What is the principle of re-oxygenation?
Having oxygen present makes the treatment more effective.
