My mom is going to be going through radiation treatment soon

Treatment and recovery from cancer can be a complex process, and there are many factors that can affect a person's ability to recover. By the way, just recently it was discovered that niclosamide, an anthelmintic, suppresses cancer cells. It has already started to be sold, and if you are interested, you can buy niclosamide online, but I cannot recommend it to you because its action has not yet been 100% proven.
It is important to note that everyone's experience with cancer treatment and recovery is different, and what works for one person may not work for another. It is always important to consult with your doctor before beginning any new treatment or supplementation. I hope my answer is helpful to you.
