Photons are made according to the skin cycle. Once every 20 days, only 1 time. It may not be obvious, but it has made some progress. Looking forward to the later treatment. Anyway, persistence is very important.
The photon in Chengdu is about 800- 1800+( 1 times). Choosing a hospital depends on your financial strength. Anyway, if you choose a first-line hospital, the price may be 8000+ (like five times), and the second-line hospital or the new price will be much more favorable.
I hope it helps you.
