rawrnr,
your tumor may still be there after 23 days of fasting, because your body has had so much work to do in eliminating your overall toxemia.
After a careful period of refeeding of about one month to prevent further toxemia, and you have regained your weight, another long fast in a body that is relatively clean would allow Autolysis to concentrate on what is left in the form of abnormal growths/effusions and yes even tumors.
Your refeeding period sounds fine, and carrot juice will be a good protocol, but I would also look into other methods such as green juices, and esp' Marine Phytoplankton (the most condensed and nutritious bioavailable superfood in existence) because when you give the body everything it needs to build healthy new cells.......you get well and recover from anything.
Have a careful read of these............... http://www.healingcancernaturally.com/marinephytoplankton-frequensea.html
