In the field of oncology, a key to treatment may be found in the tumor cells themselves. The cells contain information that can guide treatment, written at a microscopic level. This approach is part of precision oncology, which aims to tailor treatment to the specific characteristics of each patient's cancer.

The idea is that the unique features of the tumor cells can provide clues about the best course of treatment. Further details about this development are available from El País, which has reported on the potential of this approach to improve cancer treatment.
