Molecularly Defined Cancers (Somatic Mutations)

Molecularly defined malignancies have distinct genetic modifications that facilitate tumour proliferation and advancement. Among these genetic modifications, somatic mutations play a crucial role. Somatic mutations happen in individual cells during a person's life because of things like age, the environment, or random mistakes in DNA replication. These mutations can turn on oncogenes or turn off tumour suppressor genes, which messes up the normal control of cell growth and causes cancer.

This means that oncologists may now group tumours by their molecular profiles instead of only by the type of tissue they came from. This method supports targeted therapy, which refers to medications that specifically attack cancer cells with the mutation while sparing healthy tissue. Learning about somatic mutations has changed how we diagnose, predict, and treat cancer, making personalised therapies possible. As research continues, new treatments that are specific to each person's molecular profile will likely lead to better results and fewer adverse effects for patients.
