Cancer Cure: How Close Are We?

Описание: Cancer is one of the most feared words in medicine. But it’s not just one disease — it’s more than 100 different diseases, each driven by unique genetic changes.

So why is cancer so difficult to cure? And are we closer than ever to changing that?

On this episode of Health Matters, Mayo Clinic oncologist Dr. Tanios Bekaii-Saab joins host Kristen Meinzer to explain what cancer really is, how it develops and why it behaves differently from patient to patient — and even from cell to cell.

They discuss:
• How genetic mutations lead to cancer
• The difference between inherited and acquired cancer risk
• Why cancer risk increases with age
• Why younger adults are being diagnosed more often
• How tumors evolve and become resistant to treatment
• The role of surgery, chemotherapy and radiation
• How immunotherapy “unlocks” the immune system
• Whether some cancers can already be cured
• Why researchers believe more cures may be possible within the next decade

Dr. Bekaii-Saab explains how early-stage cancers can often be cured, how advanced cancers are becoming more treatable and why immunotherapy is one of the most promising frontiers in cancer care.

They also explore the importance of screening and prevention — including colonoscopies, mammograms, low-dose CT scans and emerging blood tests that may one day detect cancer even earlier.

More than 600,000 Americans die from cancer each year. But survival rates are improving. Research is accelerating. And there is real reason for hope.

If you’ve ever wondered whether a cancer cure is possible — or how close we might be — this conversation offers clarity, context and cautious optimism grounded in science.
