Medical experts have addressed a long-standing fear surrounding cancer diagnosis, firmly debunking the myth that a biopsy can cause cancer to spread in the body. Oncologists say this misconception is one of the major reasons patients delay undergoing essential diagnostic tests, often resulting in cancers being detected at more advanced and harder-to-treat stages.
A biopsy is a standard medical procedure in which a small sample of tissue is removed from a suspicious lump or lesion and examined under a microscope to determine whether cancer is present. Experts emphasise that modern biopsy techniques are safe, precise, and designed to minimise any risk, making them a critical step in confirming a cancer diagnosis and planning appropriate treatment.
According to cancer specialists, there is no scientific evidence to support the belief that biopsies cause cancer cells to spread. While rare cases of tumour cell displacement have been documented in medical literature, doctors note that these instances are extremely uncommon and do not translate into meaningful disease progression or worse outcomes for patients. The benefits of accurate diagnosis far outweigh these minimal theoretical risks.

Doctors warn that fear-driven delays can be far more dangerous than the biopsy itself. Postponing diagnostic procedures often allows cancer to grow unnoticed, reducing treatment options and survival chances. Early detection, made possible through timely biopsies, significantly improves prognosis in many cancers, including breast, lung, and oral cancers.
Experts also point out that biopsy methods have evolved significantly, with minimally invasive techniques such as needle biopsies and image-guided procedures now widely used. These approaches reduce trauma, improve accuracy, and allow clinicians to diagnose cancers earlier than ever before, often without the need for major surgery.
Health professionals are urging the public to rely on verified medical advice rather than myths or anecdotal fears. They stress that understanding the role of biopsies and acting promptly on medical recommendations can save lives, reinforcing that timely diagnosis remains one of the most powerful tools in the fight against cancer.
