Here is an US Patent for you about injecting Chlorine Dioxide / compositions directly in the cancerous tumor and/or in the body. PDJTrump once spoke about this treatment, can you remember?

"......The Chlorine Dioxide compositions are administered (preferably, by injection) directly into the cancerous tumor and the resulting tumor is effectively eliminated from the patient or subject over a period of one to several days to a few weeks, often after a single injection or multiple injections at one time into the tumor. Often, an initial injection or multiple injections at one time are sufficient to dissolve the cancerous tumor. Often the cancer is eliminated (as evidenced by remission) in a period of no more than several days to about two-three months and does not recur...."

I don´t know if it´s real hope, but I personally would try it. It is a patent. What means, it works. And somewhereI read that you have a lawyer.
Prayers and more for you. 🧡✝️
