Oncologist Debunks 4 Common Cancer Myths

Many people turn to internet searches when they experience unusual health symptoms. However, medical experts warn that online information can sometimes spread misconceptions and unnecessary panic, especially regarding serious illnesses such as Cancer.

According to Dr Kartik Krishnan, a surgical oncologist at the Head Neck Cancer Institute of India, several myths about cancer continue to circulate widely online and may confuse patients about the disease and its treatment.

Speaking about these misconceptions, the doctor emphasised that accurate medical advice should always come from healthcare professionals rather than internet sources.

Myth 1: “Sugar Feeds Cancer”

One of the most common claims is that eating sugar directly causes or worsens cancer.

Dr Krishnan explained that this idea is often misunderstood. While cancer cells use glucose for energy, so do normal healthy cells in the body. Eliminating sugar entirely does not stop cancer growth.

He noted that avoiding sugar unnecessarily may weaken the body rather than prevent disease.

Myth 2: “Biopsies Can Spread Cancer”

Another widespread belief is that procedures like biopsies may cause cancer to spread.

A biopsy involves removing a small tissue sample from a suspicious area so doctors can examine it under a microscope.

According to Dr Krishnan, the risk of cancer spreading due to a biopsy is extremely low, and the test remains one of the most important tools for diagnosis and treatment planning.

In fact, avoiding a biopsy when medically recommended could delay proper diagnosis and treatment.

Myth 3: “Natural Remedies Can Cure Cancer”

Some people believe herbal treatments or natural remedies can cure cancer without medical therapy.

However, Dr Krishnan said there is no scientific evidence that herbs, diets or natural products alone can cure cancer.

He also warned that certain herbal remedies may interfere with prescribed medications, potentially making treatments less effective or increasing side effects.

Myth 4: “No Family History Means No Risk”

Another common misconception is that cancer only affects people with a family history of the disease.

Dr Krishnan explained that only about 5% to 10% of cancers are hereditary.

Most cases develop due to a combination of lifestyle factors, environmental exposure and natural genetic changes that occur as people age.

This means individuals without a family history can still develop cancer.

Importance of Professional Medical Advice

Experts say while the internet can provide useful information, it should not replace professional medical consultation.

Doctors advise people experiencing persistent or concerning symptoms to seek guidance from qualified healthcare professionals rather than relying solely on online searches.

Greater awareness and accurate information can help individuals make informed health decisions while avoiding unnecessary anxiety.
