kræftgenomik

Kræftgenomik, or cancer genomics, is the study of the complete DNA of cancer cells. This field focuses on identifying the genetic mutations that drive cancer development and progression. By analyzing the genome of a tumor, scientists can pinpoint specific alterations in genes that are responsible for uncontrolled cell growth, resistance to treatment, and the ability of cancer to spread.

The primary goal of kræftgenomik is to understand the molecular basis of cancer. This involves sequencing the DNA of tumor cells and comparing it to the DNA of normal cells from the same patient. This comparison highlights the somatic mutations, which are changes that occur after conception and are not inherited. These mutations can be single nucleotide changes, insertions, deletions, or larger structural rearrangements within the DNA.

Understanding these genomic alterations has profound implications for cancer treatment. It allows for the development of targeted therapies, which are drugs designed to specifically attack cancer cells with particular mutations, while sparing healthy cells. This approach can lead to more effective treatments with fewer side effects compared to traditional chemotherapy. Furthermore, kræftgenomik plays a crucial role in identifying biomarkers that can predict a patient's response to certain therapies or their prognosis.

The field is rapidly evolving with advancements in sequencing technology, making it faster and more affordable to analyze cancer genomes. This has led to large-scale projects aimed at cataloging the genomic landscape of various cancer types, providing a comprehensive resource for researchers and clinicians. Ultimately, kræftgenomik aims to personalize cancer care, moving towards a future where treatment is tailored to the unique genetic profile of each individual's tumor.
