ANSWER - These kind of questions always cause me great sadness as it is with regret that I must tell you I do not have any spells that will cure a terminal illness. Healing in the world of magic is, at least in my opinion, primarily about reducing symptoms and also no less importantly about helping the family and the terminally ill person come to terms with what is happening. I'm not saying it would be impossible for an experienced witch with a good understanding of healing to slow down the symptoms and possibly to even eliminate the cause of cancer (I'm speaking hypothetically here - I know no witch myself who makes the claim that she has entirely cured a patient of cancer) but it would take a good deal more effort than working a single spell. If I claimed to be able to cast a spell over the internet without knowing your aunt personally, with no physical contact and no deep understanding of the specifics of the illness I would be nothing but a charletan. I have more respect for my readers than to offer what would amount to nothing but a placebo.
I say I am unwilling to offer a placebo but what I really mean is I am unwilling to offer a placebo to you under the guise of being an all powerful healing witch claiming the power to cure cancer.
To my mind a placebo is actually a type of magic in itself. It is harnessing the power of the mind and the belief of the individual to heal themselves. There are many many documented cases of people being healed because they believe in the treatment they have been given (This is essentially how homeopathy works). This is something that you may wish to look at but I would only be prepared to get involved with generating a placebo effect with your full knowledge that I am not casting magic of my own but rather stimulating the natural magic of your aunt's own power - the idea being that if we can generate something she believes in enough, it may well help her to fight back against the cancer.
In terms of sending strength and support with a blessing, this of course I am very willing to do. I am happy to lend my thoughts and energies to your aunt and to light a candle for her recovery. I will also send positivity to yourself and your family. It is important to understand this is not a spell for a miracle cure, more a blessing to hope that her comfort is eased.
I wish good health for your aunt and acceptance and peace for yourself and your family. If you would like to look at working a placebo charm please contact me again and I will be happy to help.
