Life Insurance Blood Tests: Cancer Detection Possible?

When applying for life insurance, you will likely be required to take a medical exam, including a blood test, to assess your overall health and risk of diseases. The blood test will be able to detect indicators of high cholesterol, glucose and blood pressure, which can indicate potential health risks or conditions. While it is unclear if the blood test can detect cancer, it can be used to detect conditions that may indicate certain types of cancers.

Cancer detection methods

Life insurance blood tests are a standard part of medical exams conducted by insurance companies to assess an applicant's overall health and risk of diseases. While these blood tests do not directly detect cancer, they play a role in evaluating an individual's health and potential risks. Here are some key points regarding cancer detection methods in the context of life insurance blood tests:

• Medical Exams: When applying for life insurance, individuals usually undergo a medical exam, which includes a blood test, urine test, and sometimes an electrocardiogram (EKG). These exams help insurance companies determine the applicant's health and risk factors.
• Cancer Screening: While life insurance blood tests do not specifically look for cancer, they may screen for certain types of cancers. For example, elevated enzyme levels or abnormal liver functions detected in blood tests could be potential indicators of cancer risk.
• Health Indicators: Blood tests check for health indicators such as high cholesterol, high blood pressure, and high blood sugar levels, which are risk factors for various health conditions, including certain types of cancers.
• Proprietary Morbidity Data: Insurance companies combine the results of medical tests with their proprietary morbidity data to assess life expectancy and the likelihood of developing critical illnesses, including cancer.
• Additional Tests: In some cases, older applicants or those seeking high coverage amounts may be required to undergo additional tests, such as an EKG or a treadmill stress test, which could indirectly provide information about overall health and cancer risk.
• Medical History: Insurance companies may also review an applicant's medical records, including the results of recommended screening tests such as mammograms and colonoscopies, which can provide information about cancer history or risk.
• Cancer Antigen Tests: In certain situations, insurance companies may request specific cancer antigen tests, such as the CEA (carcinoembryonic antigen) test, which can be a marker for the recurrence of certain cancers.
• No Direct Cancer Testing: It is important to note that life insurance blood tests do not routinely test for cancer. Most cancers are aggressive and challenging to detect in the early stages, so insurance companies focus on evaluating overall health and risk factors rather than direct cancer detection.

Blood test accuracy

Blood tests are a common requirement when applying for life insurance. They are used to assess the applicant's overall health, risk of diseases, and drug use. While these tests can provide valuable information, they are not always accurate or comprehensive.

Firstly, it is important to note that blood tests alone cannot detect most types of cancer. They can, however, help detect certain blood cancers, such as non-Hodgkin lymphoma, leukemia, and lymphoma. For solid organ cancers, like lung, breast, or colon cancers, additional tests are usually necessary.

Blood tests for cancer typically fall into four main types:

• Complete Blood Count (CBC): This test can detect blood or immune system cancers but not solid organ cancers. It helps determine how the body responds to treatment and if the cancer has spread to the bone marrow.
• Tumor Marker Blood Tests: These tests identify high levels of certain chemicals in the blood, which can indicate cancer. Examples include the CA-125 test for ovarian and pancreatic cancer and the PSA test for prostate cancer.
• Blood Protein Tests: These tests check for abnormal protein levels, which may point to certain blood cancers.
• Circulating Tumor Cell (CTC) Tests: This type of liquid biopsy detects tiny pieces of tumors circulating in the bloodstream and is used to predict outcomes in people with metastatic breast, prostate, or colon cancers.

While these tests can be useful, they should be interpreted cautiously and in combination with other diagnostic tools. Imaging tests, biopsies, and specialised tests like mammograms or Pap smears are often necessary for a comprehensive evaluation.

Furthermore, blood tests for life insurance purposes also have certain limitations. They can reveal prescriptions, drug use, and tobacco or marijuana use. However, certain variables, such as diet and supplements, can lead to false positives. For example, the presence of nicotine in the system may not distinguish between occasional cigar smoking and regular cigarette smoking.

In conclusion, while blood tests play a crucial role in assessing health for life insurance purposes and can provide valuable insights into potential diseases, they should be complemented by additional tests and interpreted within the broader context of an individual's health.

Cancer types detected

Cancer is not one of the main things that life insurance blood tests are looking for. However, they do check for a few specific types of cancer.

• Prostate cancer: Prostate-specific antigen (PSA) tests are often carried out on male applicants over the age of 50. This is because 95% of prostate cancer cases occur in men aged 50 and older.
• Recurrence of certain cancers: In some cases, ING (a life insurance company) requests a CEA (carcinoembryonic antigen) test, which can be a marker for the recurrence of certain cancers.
• Other forms of cancer: Life insurance companies do not routinely test for other forms of cancer. This is because most cancers are hard to detect in the early stages and are often aggressive. However, insurers do review the results of recommended screening tests, such as mammograms and colonoscopies, carried out by the applicant's physician.

It is important to note that life insurance blood tests are primarily used to assess overall health, risk of diseases, and drug use.

Cancer types not detected

Blood tests are one of the many ways that healthcare providers diagnose, stage, and manage cancer. However, blood tests alone cannot detect most types of cancer.

• Lung cancer
• Breast cancer
• Colon cancer
• Kidney cancer
• Bladder cancer
• Cervical cancer
• Prostate cancer
• Adrenal Cortical Carcinoma
• Bile Ducts, Intrahepatic
• Bile Ducts, Perihilar
• Esophagus and Esophagogastric Junction
• Gastrointestinal Stromal Tumor
• Gestational Trophoblastic Neoplasms
• Melanoma of the Skin
• Merkel Cell Carcinoma
• Malignant Pleural Mesothelioma
• Nasal Cavity and Paranasal Sinuses Nasopharynx
• Neuroendocrine Tumors of the Appendix
• Neuroendocrine Tumors of the Colon and Rectum
• Neuroendocrine Tumors of the Pancreas
• Oropharynx (with and without HPV mediation)
• Ovary, Fallopian Tube and Primary Peritoneum
• Soft Tissue Sarcoma of the Abdomen and Thoracic Visceral Organs
• Soft Tissue Sarcoma of the Head and Neck
• Soft Tissue Sarcoma of the Retroperitoneum
• Soft Tissue Sarcoma of the Trunk and Extremities
• Ureter, Renal Pelvis
• Uterus, Carcinoma and Carcinosarcoma

It is important to note that while these cancer types may not be directly detectable by blood tests, blood work can still play a crucial role in cancer management and treatment. For example, blood tests can help assess organ function, screen for drug use, and provide valuable information about overall health. Additionally, certain blood cancers, such as leukemia, lymphoma, and multiple myeloma, can be detected through blood tests.

Alternative detection methods

While blood tests are a common way to detect cancer, they are not the only method. Here are some alternative ways to detect cancer:

Imaging Tests

Imaging tests such as X-rays, CT scans, MRI scans, and PET scans are often used to locate and stage tumours. These tests can help healthcare providers identify the presence and extent of cancer in the body.

Biopsy

A biopsy involves taking a small sample of tissue, either from an organ or bone marrow, and sending it to a laboratory for analysis. This is a common way to confirm a cancer diagnosis.

Mammography

Mammography is a breast cancer screening method that uses X-rays to create images of the breast. It is recommended for women over the age of 40, especially those between 50 and 69, and has been shown to reduce deaths from breast cancer.

Pap Tests

Pap tests, along with Human Papillomavirus (HPV) tests, are recommended for cervical cancer screening. These tests can detect abnormal cells, allowing them to be treated before they turn cancerous.

Colorectal Cancer Screening

Several tests can be used to detect colorectal cancer, including colonoscopy, sigmoidoscopy, and stool tests. These tests can also help identify abnormal colon growths, known as polyps, which can be removed before they become cancerous.

Lung Cancer Screening

Low-dose helical computed tomography, a type of CT scan, has been found to reduce lung cancer deaths among heavy smokers. This screening method is recommended for current or former heavy smokers between the ages of 50 and 80.

Multi-Cancer Detection Tests (MCD)

MCD tests measure biological signals in body fluids that may be shed by cancer cells. These signals, also known as biomarkers or tumour markers, can indicate the presence of cancer. However, these tests are still being researched, and none have been approved by the US Food and Drug Administration yet.

Tumour Marker Blood Tests

These tests identify certain chemicals released into the bloodstream daily. High levels of these chemicals can be a sign of cancer. The CA-125 blood test, for example, is used to plan treatment and check for the recurrence of certain cancers, such as ovarian and pancreatic cancers.

Proteomics-Based Plasma Test

A 2024 research study found that a new blood test may be promising for the early detection of 18 different types of cancer. This test focuses on proteomics, which is the study of cell proteins and how they work. While more research is needed, this blood test could become a standard tool for cancer diagnosis.
