How is the time for each upgrade determined?
Whether to increase the radiation dose (times) each time during continuous treatment and what is the dose (times) ratio?

If mild erythema develops after the last treatment and resolves during treatment, the dose or duration of the last exposure should be increased by 10%

If the erythema remains severe during treatment, accompanied by pain or even blisters, treatment should be interrupted
If there is no response to the previous dose, the dose or the duration of the previous dose may be increased by 20%. For example, if your initial dose is 30 seconds and there is no response to treatment after taking the dose, you can take the second dose in 36 seconds
