Cancer Screening

What is cancer screening? Cancer screening means testing your body for cancer. Cancer screening saves lives because it can find cancer early when it’s easier to treat or cure.

  • Screening can find cancer early when it’s easier to treat or cure.
  • Cancer screening can lead to better health outcomes.
  • Screening should be done when you are feeling healthy and have no symptoms.
  • Get your questions answered and learn more about cancer screening from Cancer Care Ontario.

When Should I be Screened for Cancer?

Use the Ministry of Health and Long-Term Care's Time To Screen Tool to help you find out when you should screen for breast cancer, cervical cancer and colorectal cancer.
