Cancer Diagnostics – How to Detect Cancer Cells

Cancer Detection Methods

I think I have cancer.’

This thought is a scary one. Fortunately, there are many ways to detect cancer in its early stages. The earlier your diagnosis of cancer, the better chance you have of getting the disease under control and into remission. 

Cancer diagnostics and genetic testing for hereditary cancer can help to identify people who are genetically predisposed to certain types of cancer. By identifying such genetic mutations, preventative measures can be prescribed to reduce the chances of cancer development.

Cancer detection methods vary depending on your symptoms and the type of cancer that is suspected. For some cancers, studies prove that certain diagnostics of cancer can save lives by effectively helping to diagnose cancer early.

For other cancers, screening tests are only advised for people who are at increased risk.

How Cancer is Diagnosed

Your physician may use one or more of the following approaches as cancer detection methods.

  • Physical exam

When figuring out how to diagnose cancer in the early stages, your doctor will check your body for lumps, abnormalities, changes in skin color, or misshapen organs, any of which can indicate cancer.

  • Laboratory tests

Lab tests such as blood and urine samples can help your doctor identify abnormalities caused by cancer.

  • Imaging tests

Imaging tests assist your doctor in examining your internal organs and bones in a noninvasive way. These tests could include bone scans, X-rays, ultrasound, magnetic resonance imaging (MRI), and positron emission tomography (PET) scans.

  • Biopsy

If you’re wondering how to detect cancer cells, a biopsy is one of the most effective cancer detection methods. During a biopsy, your doctor will collect a sample of cells for testing in a laboratory. Once collected, these cells will be examined for abnormalities and signs of cancer.

Effective Screening Tests 

Effective screening tests are cancer detection methods designed to catch cancer in its early stages, before it causes symptoms. Doing so will make it easier to treat successfully. Such tests can be deemed effective if they:

  • Discover cancer early
  • Reduce the chance of death from cancer for some who is screened regularly
  • Have more potential benefits than harms. (Potential harms related to screening tests include inaccurate test results, bleeding, and the diagnosis of cancers that would not have caused problems and don’t need treating.

Some cancer detection methods include:

Colonoscopy, sigmoidoscopy, and stool tests

Several screening tests have proved to reduce the risk of death from colorectal cancer. Both colonoscopy and sigmoidoscopy can detect and prevent this type of cancer. This is because these tests can identify polyps that can be removed before they become cancerous.

Low-dose helical computed tomography

This test helps screen for lung cancer and has proved to reduce lung cancer-related deaths in heavy smokers aged between 55 and 74.


This method helps screen for breast cancer and reduce deaths from the condition among women aged between 40 and 75. It’s especially effective in women aged 50 and over.

Pap test and human papillomavirus (HPV) testing

These tests used in combination or alone can prevent cervical cancer and help to detect it in its early stages. They help prevent cervical cancer by identifying abnormal cells and treating them before they develop into cancer.

Testing is recommended to start at the age of 21 and end at 65 for women who have had adequate prior screening and are at low risk for cervical cancer.

Effective Diagnostic Tests for Cancer

There is no single test that can 100% diagnose cancer. Instead, a thorough examination of a patient is required. This examination will look at a patient’s medical history, examine their physical condition, and run various diagnostic tests.

Several tests are needed to determine whether or not a person has cancer, and effective diagnostic testing can confirm or eliminate the disease’s presence. Cancer detection methods can also be used to monitor the disease’s progress and evaluate how effective treatment has been.

In some cases, diagnostic testing must be repeated several times to see how much a condition has changed, if the samples collected were good quality, and if abnormal test results require confirmation.

Diagnostic procedures for cancer can include tumor biopsy, laboratory tests, surgery, genetic cancer testing, and endoscopic examinations.

After Cancer is Diagnosed 

If your biopsy or other diagnostic test results show that you have cancer, you’ll probably require further tests to help your medical team plan treatment. For example, your oncologist will have to determine the stage of your cancer. 

For certain cancers, figuring out the risk group you fall into, or the tumor’s grade, is vital. This is because your tumor/s grade will help your doctor decide the most effective form of treatment. Your tumor may also need to undergo further testing other genetic or tumor markers.

TruGenX Provide Genetic Cancer Testing

Hereditary cancers are caused by genetic mutations passed down from parents to children. Hereditary diagnostics for cancer are one of the most effective cancer detection methods and can help patients quantify their risks as well as determine preventative treatment plans.
