Cancer Screenings

According to the American Cancer Society, there will be an estimated 1.9 million new cancer cases diagnosed in the United States in 2022. Over 600,000 of these cases will result in cancer deaths. Early detection and treatment of cancer are becoming increasingly important as cancer diagnoses continue to rise.

Routine cancer screenings allow for the early detection of cancer and reduce the chances of death from cancer. When cancer is detected early, necessary treatments can begin earlier and treatments are more likely to be successful. Today, there are a number of cancer screenings available. Knowing what screenings exist and the guidelines for each can help you stay on top of cancer prevention.

What Cancer Screenings Are There?

Although not all cancers have screening tests, it’s important for both men and women to know which cancer screenings are available and the guidelines for them. Below are the most recommended cancer screenings deemed effective by experts.

Pap and HPV tests are given to help detect and prevent cervical cancer. Pap tests, also called Pap smears, detect precancerous cells on the cervix that may become cervical cancer if left untreated. HPV tests detect the virus human papillomavirus that can lead to these changes in the cells.

Colorectal Cancer

Colorectal cancer screenings aim to detect precancerous polyps to allow for removal before they turn into cancer. If cancer is already present, screening allows for earlier detection and treatment. The most common screenings for colorectal cancer include:

  • Stool Tests
  • Flexible Sigmoidoscopy
  • Colonoscopy
  • CT Colonography (Virtual Colonoscopy)

The colonoscopy is currently the most effective test available for colon cancer screening. This procedure allows your doctor to view the entire colon and remove polyps and abnormal tissue during the exam.
