As a trusted medical oncologist in Ahmedabad, Dr. Viraj Lavingia regularly encounters patients who arrive with deeply held beliefs about cancer that simply aren't true. Let's clear the air on the most common ones.
Myth 1: "Chemotherapy Will Make You Extremely Sick"
Reality: This is one of the most persistent fears around cancer treatment, and one of the most misunderstood. While chemotherapy does have side effects (nausea, fatigue, and hair loss are real possibilities), the experience varies widely from person to person, depending on the drug type and dosage. Modern medicine now has highly effective anti-nausea medications and supportive care that make the process far more manageable than it was even a decade ago. Many patients continue working and managing daily routines during treatment.
Myth 2: "Cancer Is Always a Death Sentence"
Reality: This thinking is decades out of date. Survival rates for many cancers, including breast cancer, thyroid cancer, certain leukemias, and early-stage colon cancer, have improved dramatically in recent years. Early detection, targeted therapies, and immunotherapy have ...
... completely transformed outcomes for thousands of patients. A cancer diagnosis today, especially when caught early, is increasingly a condition that can be treated, managed, and in many cases, fully cured.
Myth 3: "If You Feel Fine, You Don't Need Treatment"
Reality: This is a particularly dangerous assumption. Cancer in its early stages frequently has no symptoms at all. Feeling well doesn't mean the cancer isn't progressing quietly in the background. This is precisely why oncologists often recommend starting treatment even when patients feel perfectly healthy, because the goal is to get ahead of the disease before symptoms appear. Waiting until you "feel sick" is, in many cases, waiting too long.
Myth 4: "Sugar Feeds Cancer, So Cut It Out Completely"
Reality: This one is partially rooted in science but wildly overstated. Yes, cancer cells consume glucose (a form of sugar) for energy, but so does every other cell in your body, including your brain. Cutting out sugar entirely does not selectively starve cancer cells. What does matter is an overall balanced and nutritious diet. Eliminating entire food groups without medical guidance is unnecessary and can actually reduce the energy your body needs to cope with treatment.
Myth 5: "Cancer Is Genetic, If My Family Doesn't Have It, I'm Safe"
Reality: Only about 5–10% of all cancers are directly inherited. The vast majority develop due to lifestyle factors, environmental exposures, and random cellular changes that occur over time. Not having a family history of cancer does not make you immune. Equally, having a family history doesn't guarantee you'll develop it either. Regular health screenings matter for everyone, not just for those with a genetic risk.
Myth 6: "Natural Remedies Can Replace Medical Treatment"
Reality: This is the most important myth to address directly. There is currently no natural remedy that has been clinically proven to treat or cure cancer on its own. Delaying or avoiding evidence-based treatment in favour of unproven alternatives can allow the disease to progress to stages where options become significantly more limited. Complementary approaches — like good nutrition, stress management, and gentle exercise can genuinely support wellbeing alongside treatment, but they should never be positioned as a substitute for it. Always discuss these openly with your oncologist.
The One Thing All These Myths Have in Common
They survive on uncertainty and delayed action. Specialists like Dr. Viraj Lavingia regularly see patients who hold off seeking help because of misinformation, and that delay often becomes the most costly part of the journey.
If you have questions or doubts, don't rely on secondhand advice or social media threads. Speak with a qualified cancer specialist who can give you clear, evidence-based answers specific to your situation.
