If you have cancer — or have had cancer in the past — this is one of the most important financial decisions you'll make. Health sharing plans handle cancer very differently from traditional insurance, and the wrong choice could leave you with hundreds of thousands in uncovered bills.

The honest answer: for most people with active cancer or recent cancer history, health sharing is the wrong choice. Here's why, and when it might actually work.

How Each Plan Handles Cancer

| Plan | Active Cancer | Cancer History | Waiting Period | Notes | |------|--------------|----------------|----------------|-------| | Zion HealthShare | Not shareable | Shareable after 36 months remission | 36 months | Most favorable cancer policy | | Medi-Share | Not shareable | Shareable after 36 months remission | 36 months | Standard cancer exclusion | | Samaritan Ministries | Limited sharing | Case-by-case | 24-36 months | Member prayer and financial support available | | CrowdHealth | Not shareable | Limited, case-by-case | Varies | Crowdfunding model, unpredictable for large needs | | Sedera | Varies by employer plan | Varies | Varies | Ask employer for specifics | | Presidio (TX only) | Covered as insurance | Covered | None | Actual insurance, covers all conditions |

The Real Cost of Cancer Treatment

To understand why this matters, here's what cancer treatment actually costs:

Chemotherapy:

• Oral chemotherapy: $1,000–$12,000/month
• IV chemotherapy: $10,000–$30,000 per session (often multiple sessions per cycle)
• A full treatment course (6–12 months): $100,000–$500,000+

Radiation:

• Per session: $2,000–$8,000
• Full course (20–30 sessions): $40,000–$240,000

Surgery:

• Tumor removal: $20,000–$150,000 depending on type and complexity
• Reconstruction: $15,000–$80,000

Total typical cancer treatment cost: $150,000–$1,000,000+

Under ACA, your out-of-pocket maximum for 2026 is $9,450 (individual). The insurer covers everything above that. Under health sharing with cancer excluded, you pay all of it.

Who Health Sharing Can Work For: Cancer Survivors

If you've had cancer in the past and are now in remission, health sharing may eventually be an option — but the timeline is long.

The 36-month rule: Zion and Medi-Share both require 36 months (3 years) of documented cancer-free status before cancer history becomes shareable. After that window, a recurrence or new cancer diagnosis would be shared like any other condition.

What "in remission 3+ years" means practically:

• Your oncologist has documented no evidence of disease (NED) for 36+ consecutive months
• You've completed all active treatment (chemo, radiation, hormone therapy)
• Routine monitoring scans are clear

Even after 36 months, most plans will require you to disclose your cancer history. Some may charge higher rates or impose additional restrictions depending on cancer type.

The Narrow Window Where Health Sharing Might Make Sense

Cancer survivor, 3+ years in remission, low recurrence risk:

Say you had Stage 1 breast cancer at 38, completed treatment at 39, and are now 43 with clean annual scans. You're healthy otherwise, high income (no ACA subsidies), paying $480/month for ACA Silver.

After 36+ months of remission, you might qualify for a health sharing plan at $215–$268/month. That's $2,500–$3,100/year in savings.

The risk: if cancer recurs, health sharing won't cover it during a new waiting period. You'd need to switch back to ACA (which you can do at open enrollment or with a special enrollment period).

For this person, the math might work — but only if they're comfortable accepting that risk and have financial reserves if they need to switch mid-year.

ACA vs Health Sharing for Cancer: The Math

For someone in active treatment, there's no comparison:

| Scenario | ACA Silver | Zion HealthShare | |---------|-----------|-----------------| | Annual premium | $5,400 | $2,580 | | Cancer treatment cost | $300,000 | $300,000 | | ACA pays | $290,550 (after $9,450 OOP max) | $0 (not shareable) | | Health sharing pays | N/A | $0 | | Your total cost | $14,940 | $305,580 |

This is not a close call. ACA wins by $290,000.

What About Samaritan Ministries?

Samaritan takes a different approach from the other plans. Their peer-to-peer model means members can voluntarily send additional support beyond the standard sharing — and Samaritan has a long history of their community rallying around members facing cancer.

This isn't guaranteed coverage. It's voluntary support on top of whatever the standard guidelines allow. Some members have received significant help through Samaritan's community during cancer battles. Others have found the support insufficient for the actual costs.

If faith community and mutual support matter to you as much as financial coverage, Samaritan is worth understanding. Just don't count on it as your primary financial backstop for cancer treatment.

The Honest Summary

Health sharing and cancer is almost always a bad combination if:

• You have active cancer or are currently in treatment
• Your cancer history is less than 3 years in remission
• You have a high-recurrence-risk cancer type

Health sharing might work if:

• You're 3+ years in remission from a low-recurrence-risk cancer
• You're healthy otherwise and don't qualify for ACA subsidies
• You understand the risk and have financial reserves to switch back to ACA if needed

For anyone facing cancer or recently completing treatment: use ACA. The out-of-pocket maximum exists specifically for situations like this.
