Common Myths About Cancer Diagnosis and Treatment

The most common complication with radiotherapy for left-sided breast cancers is cardiotoxicity. Radiation oncologists manage this with deep inspiratory breath-hold and gating techniques, training the patient to hold their breath during the active phase of radiotherapy so toxicity to the heart is reduced, chest wall motion is reduced, and radiation is delivered accurately to the target volume. More precise machines such as IGRT and 4D-CRT are also improving precision for left-sided breast and chest wall tumours.

Until very recently, patient assistance programmes for targeted therapy and immunotherapy were only available to Indian patients. Because these drugs are costly, companies assist with procuring them at up to a half or a third of the usual cost, which is out of reach for many domestic Indian patients too because of regulations. These regulations are now relaxing, and more international patients are able to receive the benefit of these programmes.

Not 20 packs per day, that would be 400 cigarettes a day, which is not possible. Pack-years is the number of packs smoked per day multiplied by the number of years smoked. Two packs a day for ten years makes 20 pack-years, as does one pack a day for twenty years, or half a pack a day for forty years.

Any suspected cancer requires resources for investigation and treatment, so it should be evaluated at a good high-volume centre that gives the best chance of cure. It is difficult to assess the outcome or treatment at an initial stage, so the primary reliance has to be on the clinical signs and symptoms already discussed, which are the basis for suggesting a patient be evaluated at a high-volume centre.

A malignant wound anywhere needs to be confirmed on biopsy to establish the exact reason for it, and it should not be expected to heal on its own. It should be subjected to a biopsy to confirm the nature of the malignancy and the treatment options, with appropriate imaging to understand the underlying structures involved, and surgery offered if the wound is resectable.

No. A biopsy, if planned and performed correctly, will not cause cancer to spread, and it remains one of the most crucial tests for confirming a diagnosis and guiding treatment.

No. While tobacco and alcohol use are risk factors for some cancers, many cases are now understood to arise from environmental exposure or genetics rather than a patient’s own fault.
