Tumor-suppressing and tumor-promoting senescence

Under what conditions does cellular senescence suppress cancer, and when does it instead promote tumor progression or lymphatic spread?

It could clarify how senescence’s opposing roles affect cancer progression and whether targeting it could help or undermine treatment.

Where it stands now

Main bottleneck

Current evidence does not establish how to reliably distinguish tumor-suppressing senescence from tumor-promoting senescence in a given cancer setting.

Watch next

Evidence identifying and testing specific conditions that determine whether senescence restrains tumor progression or promotes it, including effects on lymphatic spread or treatment response.

    Since the previous research note: How growth-arrested cells may reshape lymphatic routes used by cancer

    Previous expectation: Selective control of senescent-cell signals might reduce cancer spread or relapse while preserving protective growth arrest and normal lymphatic functions.

    What this study adds: The August 2024 review broadens the discussion to cancer-specific treatment responses, sequential senescence induction and clearance, and barriers to selective targeting. Its reviewed cell and mouse findings do not test the earlier forecast's lymphatic-function and patient-relapse conditions.
