Just putting it out there as I personally have had amazing success.
Euphorbia plepus, milkweed, cancer weed.
If the white sap stings, continue application until no reaction. Is painful during healing, but 21 days cleared a dime size growth on my throat over 2 years ago, with no recurrence.
Does not react on healthy skin.
My doctor also recommended surgery, and wasn't interested when I presented a month later with no further issue.
Best of luck.
