What is worth screening for? High blood pressure, cervical cancer in women and aortic aneurysms in male smokers over 65. Breast cancer: probably. Air Jordan Retro 1 Orange Grey Bowel cancer: probably providing the investigation doesn't kill too many people (screening is by testing for faecal blood followed by colonoscopy if positive). Prostate Air Jordan Retro 1 Orange Grey cancer (by PSA test): unproven. Lung cancer(by CT scan): unproven. Kidney cancer: rare and not looked into but personally I think worth screening for by ultrasound.
