Here are some ways in which one can diagnose and prevent the onset of cancer at an early stage.

1. Pay attention to symptoms and get yourself checked regularly.
2. Using any type of tobacco puts a person at an increased risk of cancer. Avoiding or stopping the consumption of tobacco is one of the foremost steps in cancer prevention.
3. Filter tap water properly as this can reduce your exposure to possible carcinogens and hormone-disrupting chemicals.
4. Get vaccinated on time and as per schedule. For example, the Human Papilloma Virus (HPV) vaccine helps prevent most cervical cancers and several other kinds of cancer.
5. Drinking plenty of water and other liquids can help in reducing the risk of bladder cancer by diluting the concentration of cancer-causing agents in urine and helping to flush them through the bladder faster.
6. Most importantly, make lifestyle changes such as eating a healthy diet and getting regular exercise. Fruits and vegetables are rich in antioxidants which can help ward off diseases.
