Genetics play a crucial role in cancer treatment by providing insights into the mutations and alterations driving cancer growth. Genetic testing and genomic profiling can identify specific mutations that can be targeted by available therapies. For instance, mutations in the EGFR gene in lung cancer or the BRCA genes in breast and ovarian cancers can guide the use of specific drugs that target these alterations. This approach leads to more personalized and effective treatments, often with fewer side effects.
