a

Female Wistar Furth rats with tumor inoculation at the age of 8 weeks, with the normal tumor dose of 105 viable tumor cells.

b

Untreated rats of the same age as the cured rats at the time of inoculation, without previous exposure to tumor.

c

These tumor-bearing rats cured by laser-ICG-GC treatment were challenged with 106 viable tumor cells 120 days after the initial inoculation.

d

Successfully treated rats from different experimental groups were challenged the second time after the first challenge.

e

Successfully treated rats from different experimental groups were challenged the third time after the second challenge.
