Sorry to hear your mums not well. Could be a wives tale but could also be fact but I have read that a couple of drops of Frankincense Oil to the roof of the mouth or under the tongue can help reduce swelling in the brain and act as an immunotherapy to the cancer.
If you can legally obtain it (check for trials in your area), cannabus oil is also now showing it can hold some cancer cells at bay. Some say it can cure some cancer but its still debatable as not enough research is present atm.
Ask your mums doctor about high dose vitamin C. It can be administered as an injection. My sis had them when she was battling Ross River disease and it gave her a boost in recovery.
