Insurance Guide for Cancer Patients: Honoring World Cancer Day

World Cancer Day is observed every year to raise awareness of the benefits of early cancer detection through routine screenings, many of which are covered by standard health insurance, Medicare and Medicaid. Early detection can increase the chance of beating cancer and living a longer, healthier life, and it may also help reduce the cost of treatment by identifying cancer before it progresses.

What Is World Cancer Day?

World Cancer Day is an international observance held annually.^[1] It’s dedicated to raising awareness of cancer, reminding people of the importance of cancer prevention through early screening and advocating for continued progress in cancer research to improve treatments. Through these efforts, World Cancer Day aims to help the global community better understand how to fight this disease.

When Is World Cancer Day?

World Cancer Day is observed every Feb. 4. The annual observance has been held on this day since its founding in 2000.^[2] Ensure you take some time out of your day this Feb. 4 to learn more about different types of cancers, ones you may be at risk for and what resources are available for those in your life who may be dealing with cancer.

Why Is World Cancer Day Important?

World Cancer Day matters because it serves as a reminder of the effects of cancer and how much still needs to be done in the fight for better treatments. In the U.S. alone, cancer results in an estimated 618,120 deaths annually, and nearly 10 million worldwide.^[3][4] Providing cancer care can be a long process, which can put a strain on health systems and may lower health outcomes for everyone, as medical professionals and care centers are stretched thinner than necessary.

Thankfully, many cancers can be detected early with screenings, leading to more effective and less costly life-saving cancer treatments.^[4] However, many still forgo regular screenings, with only 51% of American adults getting a routine cancer screening in 2025 — a 10% decrease over the previous year. This makes education and awareness observed during World Cancer Day so important for increasing routine screening and improving treatment effectiveness, as 73% of people are more likely to schedule screenings after learning about the benefits of early detection.^[5]

World Cancer Day is also about celebrating the progress the global community has made in battling cancer. Between 1991 and 2019, cancer deaths fell by 32%, with much of this decline due to people living longer with lung cancer thanks to earlier detection.^[6]

By recognizing these achievements, World Cancer Day can highlight the proven benefits of early detection and help reduce the stigma around screening.

World Cancer Day History

World Cancer Day was originally founded by the Union for International Cancer Control (UICC). The UICC was founded in 1933 in Geneva, Switzerland, and currently includes more than 1,120 member organizations spanning 172 countries and territories, making it both the largest and oldest international organization dedicated to combating cancer.^[2]

On the date that would become World Cancer Day, various government agencies and cancer organizations signed the Charter of Paris Against Cancer, also known as the Paris Charter, in France at the World Summit Against Cancer. This charter outlined a commitment to improving the quality of life for those living with cancer, advancing cancer research, developing new and better treatments and expanding knowledge of prevention techniques to reduce the global cancer burden.^[7]

Every few years, a theme is chosen to represent the World Cancer Day campaign and serve as a focus for reflection.

The theme from 2025 to 2027 is “United by Unique”, which advocates for a people-centered approach to providing cancer care that acknowledges each person’s journey with cancer as a unique human story and should be met with empathy and understanding.^[8]

How Does Health Insurance Support Preventive Cancer Screenings?

Health insurance helps support preventive cancer screenings by covering the costs of most recommended exams, including mammograms, colonoscopies and Pap tests. Due to mandates covered by the Affordable Care Act (ACA), most of these cancer screenings have no out-of-pocket costs, including copayments and coinsurance — even if you haven’t met your deductible.^[9][10]

What Diagnostic Tests for Cancer Are Typically Covered by Insurance?

While not all diagnostic screening tests for cancer are entirely covered by health insurance, the following are, provided you meet the qualifications:^[11]

• Mammograms: Tests for breast cancer. Only women ages 40 to 74 are covered for a test every one to two years.
• Pap tests: Also called Pap smears, these tests screen for cervical or gynecologic cancer. Only women ages 21 to 65 are covered for a test every three years. Alternatively, women ages 30 to 65 who don’t wish to have a Pap smear as frequently can opt for a human papillomavirus (HPV) test combined with a Pap smear every five years.
• Colonoscopies: Tests for colon cancer. These are covered for adults over 45 every 10 years, or more frequently for less invasive screening types.

These exams are typically only covered in network, and seeing a provider outside of your network may mean these exams have out-of-pocket costs. You may also be covered for other cancer screenings, depending on your risk factors. However, you may not be completely covered for all costs with these types of tests:^[11]

• Gastric, endometrial, prostate, pancreatic or ovarian cancer screenings
• Clinical breast exams
• Mammograms for women younger than 40
• Mammograms for men
• Colonoscopies for those younger than 45 or more frequently than every 10 years
• Other screening interventions, such as a breast MRI or ultrasound

Those who are on Medicare are covered for mammograms, Pap smears and pelvic exams, colonoscopies and a prostate cancer exam, provided they meet necessary requirements. However, Medicare typically doesn't cover preventive cancer screenings outside of these options. Medicaid may cover cancer screenings, but coverage options vary by state.^[11]
