Oct 02, 2020 · Ultra-high dose rate (FLASH) radiotherapy is a new way of treating tumours caused by cancer. Higher doses of radiotherapy are associated with trauma to the healthy tissue surrounding the tumour, whereas FLASH radiotherapy demonstrates a sparing effect of the healthy tissues without compromising the anti-tumour action.
Why are hot flashes a problem for breast cancer patients?
Jan 17, 2020 · Flash-Rt Limits Normal Tissue Toxicity. Investigation of the dose rate at which RT is delivered harks back to the 1960s, when it was demonstrated that non-cancerous mammalian cells irradiated at ultra-high dose rates had greater viability than those irradiated at conventional dose rates ( 21 ).

What is flash RT?
FLASH radiotherapy (FLASH-RT) is a new technique, involving treatment of tumours at ultra-high dose rates which actually reduces the trauma to normal tissue around the tumour, whilst equalling the anti-tumour effect of conventional dose rate radiotherapy (CONV-RT). However, very little is known about the mechanisms behind the FLASH effect.

Does estrogen affect vasomotor function?
Changes in the balance, possibly related to the direct or indirect action of estrogen, could theoretically induce a vasomotor response. Functional estrogen receptors have been found in human vascular smooth muscle, suggesting that estrogen may also have a direct and important role in vascular function13.
