What kind of cancer screening tests are recommended?

There are a number of common cancer screening tests that are considered quite effective and are recommended by the experts.

  • Cervical cancer screening – HPV and Pap tests are the cervical cancer screening tests that are recommended done alone or combined. These tests will prevent diseases because they enable abnormal cells to be detected and even treated before they turn into cancer.
  • Colorectal cancer screening – It is seen that many screening tests, which include colonoscopy, stool tests, etc. have shown a reduction in the death risk from colorectal cancer. Apart from the early detection of colorectal cancer, these health screening tests can help in preventing the disease from developing. These tests are able to find abnormal growth in the colon that can be removed before becoming cancerous. People who have a risk for colorectal cancer should go for screening from age 45.
  • Lung cancer screening – CT scans for cancer screening have resulted in the reduction of lung cancer deaths among people who are heavy smokers.

How is cancer diagnosed?

The doctor can use one or more of the following approaches for diagnosing cancer –

  • A Physical exam – Feeling the areas of your body for any lumps that can indicate cancer. The doctor will look for any kind of abnormalities, like a change in the colour of the skin or organ enlargement.
  • Laboratory tests – Lab tests like urine and blood tests can help the doctor identify any abnormalities for example, for patients suffering from leukemia, a complete blood count is able to reveal an abnormal amount or kind of white blood cells.
  • Imaging tests – The doctor can examine the bones as well as the internal organs in a non-invasive way. Imaging tests used commonly are CT scans, bone scans, MRI, PET scans, ultrasound, as well as X-ray, among others.
  • Biopsy – The doctor will collect cell samples for testing. The correct biopsy procedure for a person will depend on the type of cancer as well as its location in the body.


A few cancers can be found early even before they can grow and spread further in the body. Regular cancer screening tests will increase the chance of the detection of certain cancers early. A thorough health screening test that is done at regular intervals is perhaps the best security against cancer. Any kind of delay can lead to dangerous consequences.
