41 3 Full Breakdown

Summary

Story summary

Tel Aviv University researchers report in Nature Genetics that chromosome 17 changes, especially p53 loss, raise breast cancer brain metastasis risk.
Impaired p53 enables cancer cells to produce more fatty acids, aiding brain growth.
Researchers identify SCD1, an enzyme tied to fatty acid production, as a potential treatment target.
Findings could improve strategies to prevent and treat brain metastases in breast cancer.
