Meaning and Definition
A gene that can promote the development of cancer when mutated or expressed abnormally.
Specifically refers to two main types: oncogenes (mutated forms of normal genes that promote cell growth) and tumor suppressor genes (normal genes that inhibit cell division; cancer occurs when they are inactivated). In broader public discourse, it can refer to any gene associated with inherited or acquired cancer risk.

- Thinking one 'cancer gene' causes all cancers.
FAQ
Frequently Asked Questions
No. It means you have an increased genetic risk or predisposition. Other genetic, environmental, and lifestyle factors also play a crucial role.
An oncogene is a mutated gene that actively promotes cancer (like a stuck accelerator). A tumor suppressor gene normally prevents cancer, and cancer occurs when it is inactivated (like a broken brake).
No. They can be inherited (germline mutation) or acquired during a person's lifetime due to environmental factors like radiation or chemicals (somatic mutation).
This is a major goal of cancer research (gene therapy, targeted drugs). Some therapies specifically target the products of mutated cancer genes, effectively 'turning off' their cancer-causing signal.

Learning
Memory Aids
Mnemonic
Think of a CANCER GENE as a broken instruction manual (GENE) inside a cell that tells it to grow out of control, leading to CANCER.
Conceptual Metaphor
A MUTATED INSTRUCTION MANUAL (the gene provides faulty instructions). A BROKEN BRAKE or STUCK ACCELERATOR in a car (oncogene = accelerator, tumor suppressor = brake).
