Cancer is widely discussed, yet myths still cloud public understanding. Clearing up misinformation is essential for prevention, early detection, and better outcomes. Here are ten common cancer myths — and the truths behind them.
* cancer Is Always Fatal
A cancer diagnosis is not a death sentence. Advances in early detection, immunotherapy, targeted drugs, and precision medicine have dramatically improved survival rates. Many cancers, when caught early, are highly treatable and even curable.
* sugar Feeds Cancer
Cancer cells use glucose, but so do healthy cells. Cutting sugar won’t starve cancer. However, excess sugar can contribute to obesity and inflammation, which may increase cancer risk. Balance matters more than elimination.
* Biopsies Spread Cancer
Biopsies do not cause cancer to spread. They are a safe and essential tool for diagnosis and treatment planning. Avoiding biopsies can delay care and worsen outcomes.
* Family history Means You’ll Get Cancer
Only 5–10% of cancers are hereditary. Most develop due to lifestyle factors, environmental exposures, or random genetic changes. Family history may raise risk, but it does not make cancer inevitable.
* mobile Phones Cause Brain Tumours
Mobile phones emit non-ionising radiation, which cannot damage DNA. Extensive research has found no credible link between phone use and brain cancer.
* cancer Is Contagious
Cancer cannot spread between people. Some infections, like HPV or hepatitis, can increase cancer risk, which is why vaccines and screenings are important.
* Herbal Remedies Cure Cancer
No herbal treatment has been proven to cure cancer. Relying on unproven remedies can delay effective medical care and reduce survival chances.
* Chemotherapy Is Always Severe
Modern chemotherapy is more targeted and better managed. Side effects are often milder and controlled with supportive medications.
* Deodorants And Plastics Cause Cancer
There is no strong scientific evidence linking deodorants or everyday plastic use to cancer. Regulatory agencies consider them safe when used normally.
* Positive Thinking Cures Cancer
A positive mindset can help emotional well-being, but it does not determine survival. Evidence-based treatment and timely care are what truly matter.
