Colorectal Cancer Blood Tests: Pros and Cons

Scientists are working on making innovative tests for colorectal cancer screening, so more people can get screened.

Colonoscopy and stool-based tests are two options for colorectal cancer screening, but blood tests present an emerging technology. Markers in the blood can indicate the presence of colorectal cancer and, occasionally, precancerous polyps. Colorectal cancer screening blood tests are now an option for some patients.

New tests are getting approved by the Food and Drug Administration (FDA) and are becoming easier for patients to access. Here is what you need to know if you are questioning if this type of screening option is a good fit for you.

Pros and Cons

When thinking about getting a colorectal cancer blood test, it’s important to weigh the benefits and drawbacks.

Pros

Here are some pros to screening for blood based tests for colorectal cancer screening:

高灵敏度2024-12-12T17:24:50+00:00

这些检查在检测结直肠癌,尤其是晚期结直肠癌方面非常有效。它们与其他用于筛查结直肠癌的非侵入性检测具有相似的检测率。这些检测能很高比例地正确识别出未罹患结直肠癌的人(Grady,2019 年)。

方便2024-12-12T17:24:44+00:00

无需请假,也无需麻醉,是一种省心的选择。您也无需进行术前准备或改变饮食习惯。

不处理凳子2024-12-12T17:24:37+00:00

与其他非侵入性检测不同,您无需处理或收集粪便样本。

简单抽血2024-12-12T17:24:14+00:00

该检测需要常规血液样本。

Cons

Here are some cons to a blood test for colon cancer:

Insurance Coverage2024-12-12T20:34:15+00:00

Since blood tests for colorectal cancer are not yet universally accepted or included in screening guidelines, insurance companies may not cover the costs (American Cancer Society, 2023).

Frequent Testing Needed2024-12-12T20:34:15+00:00

Tests will need to be repeated every 1-3 years to maintain their effectiveness.

Follow-up Colonoscopy Required2025-01-29T22:28:36+00:00

Like a stool test, if you get a positive result from the blood test, a follow-up colonoscopy is necessary.

有限的预防能力2025-01-11T03:43:34+00:00

与 FIT 或 mt-sDNA 等许多基于粪便的检测相比,血液检测在识别癌前息肉(这对预防至关重要)方面并不那么有效。此外,结肠镜检查仍是唯一能在一次检查中识别并切除癌前息肉的检查方法。(Ladabaum, 2018)。

Should You Consider a Blood Test for Colorectal Cancer?

Discuss your screening options with your medical provider. Ask if a blood test is suitable for you. Keep in mind that a blood test will not be recommended if:

  • You are at an increased or high risk for colorectal cancer.
  • You or a first-degree biological family member have had previous colorectal cancer(s) or advanced adenomas/precancerous polyps.
  • You have signs or symptoms.

Every screening test has its pros and cons. Consider all your options and choose the one that best fits your health history and your needs.

What should I do if I want to try this option?

Blood tests for colorectal cancer screening, just like colonoscopy and stool-based tests, should be ordered by a healthcare provider. To find out if blood tests are a good option for you, talk to your primary care physician, gastroenterologist, or OBGYN.

Will my insurance pay for this test?

If you and your doctor think a blood test is a good option for you, check with your insurance to see if it’s covered. If your insurance does not pay, you might have to pay for the blood test. Messaging your doctor online or contacting the office by phone can help you avoid extra appointments. Call and ask if a blood test could be an option for you.

Currently, most insurance plans do pay for colorectal cancer screening options which are in USPSTF guidelines. (At this time, blood testing is not part of the USPSTF guidelines).

Some companies that make blood tests provide programs to help patients pay for the tests like Guardant Access.
