Cortisol Linked to Cancer Spread: New Research
22 Feb
Summary
- Stress hormone cortisol may increase cancer cell resilience.
- Disrupted cortisol rhythms in patients promote tumour growth.
- Mindful activities like nature time may aid cancer patients.
Scientists have uncovered a potential link between the stress hormone cortisol and the progression of cancer. Research indicates that cortisol may play a role in making tumours more resilient and challenging to treat.
Normally, cortisol levels follow a daily rhythm, peaking in the morning and lowering in the evening. However, this pattern is disrupted in cancer patients, leading to more consistent levels. This 'steady-state' of cortisol has been shown to enhance 'stemness' in cells.
'Stemness' refers to a cell's capacity for renewal, adaptation, and spreading, all of which contribute to tumour growth. The findings suggest that mindful activities, such as spending time in nature, might help mitigate these effects, mirroring practices observed in figures like the Princess of Wales.
