My son had Leukemia diagnosed in March 2020. He got Car-T treatment which is similar to crispr. His cancer was gone within a month. It’s amazing what science and technology is capable of. So far 2.5+ years and still no trace of the cancer coming back. Even his own immune system which was eradicated as a part of the treatment is starting to show signs of coming back. God bless this patient and hopefully they will get back to a normal life like my son has been able to do.
