For many patients, chemotherapy is the first weapon used against cancer. But what happens when it stops working? Why do some cancers become resistant — and what can you do about it?

At Cancer Expert MD, we believe that understanding why chemotherapy fails is critical. More importantly, we believe in personalizing your care with advanced testing, integrative therapies, and evidence-based natural compounds that can enhance — not replace — your treatment.

 Why Does Chemotherapy Stop Working?

Chemotherapy targets rapidly dividing cells, but over time, cancer adapts and learns how to survive. Common reasons chemo stops working include:

• Genetic Mutations — Cancer mutates, making it resistant to standard drugs.
• Drug Efflux Pumps — Cancer cells develop mechanisms to pump chemo drugs out.
• Cancer Stem Cells — These persistent cells survive chemotherapy and fuel recurrence.
• Tumor Microenvironment — Conditions like hypoxia (low oxygen) and acidosis (high acidity) protect cancer cells from chemo’s effects.

 Test Before You Treat — The Smarter Approach

You wouldn’t take a medication without knowing if it works — so why guess with chemotherapy?

At Cancer Expert MD, we use the latest testing to guide your treatment plan:

 Chemo-Sensitivity Testing

• Tests your live tumor cells against multiple chemotherapy drugs.
• Identifies the drugs most likely — and least likely — to be effective.
• Prevents unnecessary side effects from ineffective treatments.

 Genomic Testing

• Identifies specific mutations linked to drug resistance.
• Opens doors to targeted therapies and advanced treatment options.

 Cancer Stem Cell Testing — The Silent Drivers of Recurrence

Cancer stem cells are stealthy survivors inside your tumor. They resist chemotherapy and can start the cancer growing again.

We offer specialized tests for circulating cancer stem cells — so you can understand your real risk of recurrence and spread.

 The Power of Natural Substances in Cancer Care

At Cancer Expert MD, we believe in a comprehensive strategy that combines both conventional and natural therapies, backed by scientific evidence.

Some natural substances have been shown to work synergistically with low-dose chemotherapy and radiation, enhancing their effects while protecting healthy cells.

Key natural compounds we may use or recommend include:

• Green Tea Extract (EGCG) — Known for its anti-cancer properties.
• Ivermectin — Being studied for its potential anti-cancer effects.
• Curcumin (from turmeric) — Powerful anti-inflammatory and chemosensitizer.
• Quercetin — Supports immune modulation and may slow cancer growth.
• Dandelion Extract — Shown in studies to target cancer cells.

 Testing Natural Substances

We can test how your tumor cells respond to certain natural substances — helping us design an integrative plan that makes chemotherapy and radiation work better.

 The Bottom Line — Don’t Fight Blind. Test First.

If chemotherapy isn’t working — or if you want to maximize your success — don’t rely on trial and error.

At Cancer Expert MD, we combine advanced chemo-sensitivity testing, genomic profiling, and integrative strategies including natural substances that work alongside your treatment — giving you the most personalized and powerful approach possible.
