Non-tumourigenic

The adjective 'non-tumourigenic' describes something that does not cause tumours, or the formation of abnormal growths of cells. It indicates a lack of the potential to induce cancer or benign neoplasms in living organisms or cell cultures. This characteristic is crucial in drug development, biomedical research, and various applications where the safety and inertness of a substance or process are paramount. A non-tumourigenic substance is considered safe in the context of cancer risk, offering a degree of confidence in its application for therapies or other biomedical purposes. The absence of tumour-inducing properties is often verified through extensive testing and rigorous experimental protocols.

Non-tumourigenic meaning with examples

• Extensive pre-clinical trials demonstrated that the new pharmaceutical compound was completely non-tumourigenic in various animal models, paving the way for human clinical trials. These results provided crucial evidence for the drug's safety profile.
• Researchers aimed to identify and cultivate a non-tumourigenic cell line for use in regenerative medicine, which would mitigate the risk of uncontrolled growth after transplantation and ensure patient safety and benefit.
• The excipient used in the formulation of the vaccine had to be proven non-tumourigenic to meet stringent regulatory requirements. Without this confirmation the vaccine couldn't be administered to the public.
• Before approval, food additives undergo rigorous testing to confirm they are non-tumourigenic. This requirement protects consumers from substances that may cause cancer after long-term exposure.
• The study compared the effects of different materials on cell growth and found the bio-compatible implant materials were non-tumourigenic. They provided the safest long-term option for the patient.
