Last summer, Susan Skarbek of Vancouver, Washington was told she had stage 4 anal canal cancer with the tumor hitting her rectum and invading her vagina and two lymph nodes. She did one round of chemotherapy but refused to continue because of the side effects. She did numerous rounds of proton radiation but was told she faced radical surgeries if it didn't clear up. However, when she began using cannabis oil, and had a checkup a few weeks ago, doctors were shocked that her original tumor was gone.
