What it is
A gene mutation is a change in the instructions that cells use to grow and function. This change occurs when there's an error in the DNA sequence, which is like a set of instructions written in a special code. Gene mutations can affect how cells work and may lead to problems like cancer.
How it works
Gene mutations happen when there's a mistake in the way DNA is copied or when environmental factors, such as radiation or chemicals, damage the DNA. In some cases, these mutations can disrupt the normal functioning of genes, leading to uncontrolled cell growth and cancer. Researchers study gene mutations to understand how they contribute to cancer development and to identify potential targets for treatment.
Why it matters
Understanding gene mutations is important for developing personalized treatments and predicting cancer risk. By identifying specific gene mutations, doctors may be able to tailor treatment plans to an individual's needs. Additionally, research on gene mutations can help scientists develop new cancer therapies and improve our understanding of the disease.
