Cancer Screenings: Which Ones Do You Really Need?


Prevention is better than cure. This adage is particularly true when it comes to cancer, a disease that takes millions of lives every year. Early detection through cancer screenings significantly increases the chances of successful treatment and survival. However, with the plethora of cancer screenings available, understanding which ones you really need can be daunting. This article aims to shed light on this crucial topic.

The Importance of Cancer Screenings

Cancer screenings are tests performed to find cancer before symptoms start. They can help spot cancer at an early stage, when treatment is most likely to be successful. Some screenings can also detect precancerous conditions, allowing doctors to intervene and prevent cancer from developing.


However, not all cancer screenings are created equal. Some have been proven to save lives, while others may cause unnecessary anxiety due to false positives or overdiagnosis. It's essential to discuss the benefits and risks with your healthcare provider to determine the right screenings for you.

Breast Cancer Screening

Breast cancer is the most common cancer among women worldwide. The two main tests used to screen for breast cancer are mammograms and breast MRI.


Mammograms are X-rays of the breast that can detect tumors that are too small to feel. The American Cancer Society recommends women aged 45 to 54 should get mammograms every year. Women aged 55 and older can switch to mammograms every two years or continue yearly screening.

On the other hand, breast MRI is used for women at high risk for breast cancer. It is usually done along with a mammogram.

Cervical Cancer Screening


Cervical cancer can be prevented through regular screening. The two primary cervical cancer screenings are the Pap test and the HPV test.

The Pap test, also known as a Pap smear, looks for precancers or cell changes on the cervix that might become cervical cancer if they are not treated. The HPV test looks for the human papillomavirus that can cause these cell changes. Women aged 21 to 29 should have a Pap test every 3 years. Women aged 30 to 65 should have a Pap test and an HPV test every 5 years or a Pap test alone every 3 years.

Colorectal Cancer Screening


Colorectal cancer is cancer that occurs in the colon or rectum. Screening tests can help prevent colorectal cancer by finding precancerous polyps so they can be removed before they turn into cancer. The most common test is a colonoscopy, which allows a doctor to look inside the entire colon and rectum for polyps or cancer. The American Cancer Society recommends that people at average risk of colorectal cancer start regular screenings at age 45.

Prostate Cancer Screening

Prostate cancer is the second most common cancer among men worldwide. The primary tests for prostate cancer are the prostate-specific antigen (PSA) test and the digital rectal exam (DRE).


The PSA test measures the level of PSA, a substance made by the prostate, in the blood. High PSA levels can be a sign of prostate cancer. The DRE is a physical exam where a doctor feels the prostate for lumps that might be cancer. The American Cancer Society recommends that men talk with a healthcare provider about the uncertainties, risks, and potential benefits of prostate cancer screening before deciding whether to be tested.

Lung Cancer Screening

Lung cancer screening is recommended for people at high risk of developing lung cancer. This includes people aged 55 to 74 years who are in good health, have a history of heavy smoking, and smoke now or have quit within the past 15 years. The primary test for lung cancer is a low-dose computed tomography (LDCT) scan, which uses low doses of radiation to make detailed images of the lungs.


Regular cancer screenings can play a crucial role in early detection and prevention of cancer. However, it's important to remember that screenings should not replace a healthy lifestyle, which is your first line of defense against cancer. It's also essential to have informed discussions with your healthcare provider about the benefits and risks of different cancer screenings to make the best decision for your health.
