Hi Artimuse,
Thank you for sharing your health issues with us and wish you a speedy and full return back to health as soon as possible. Well done on getting Level 1 and hope it is all going well for you. There are some very experienced people on this forum in terms of SFQ but I will do my best to answer your question if I can.
I am sure you have asked yourself how the tumour may have come about in the first place - emotions, nutrition, physical trauma/accident, stress and that may hold the key to resolving it. It all depends on how serious it is and how much time, effort and money you wish to devote to getting to the bottom of it and how urgent you feel within yourself that it be resolved.
Level 1 is great within itself and I would say can get you a long way and it may be enough within itself but as I have heard many times - good, better, best. Best for you may be to get Level 2 and the phone healing as well and therefore coming at it from as many angles as possible. At the end of the day there are no gaurantees to any of this or any other modality and you have to just trust, listen for your gut feeling and follow where it might lead - it will always have your best interests at heart.
Level 2 and the Born a Healer book as well have so much great info in it that I am very glad I listened to my intuition and went for it. My health is improving after some 7 years of searching for answers and following each route the Universe placed before me. I have now spent over £14,000 trying to solve my issues but wouldn't change this journey for the world - although I do wish to see the day when I am pain free don't get me wrong!
So I would say Level 2 is well worth it and if you have a friend who is willing to learn and help themselves as well then you could give each other daily treatments - how special would that be!
Let us know how you get on.
Yours in health and friendship,
David
