I fully understand what Grace and Rohany say about the filipino culture and concept of "bahala na", and appreciate your input ! But all the faith and support of family and friends, not to mention money, will not cure these diseases when they're advanced.
Both diabetes and bowel cancer are classic examples of common illnesses both in UK and Philippines where early diagnosis and treatment will save lives ! Treatment of both at an early stage is less expensive (however it is paid for), and more effective. Simple tests can be carried out for diabetes, and now in the UK we have a bowel cancer screening programme for those most at risk. But even without screening, awareness of early symptoms and attending the doctor could save illness and your life.
