Firstly I congratulate you on embracing alternative methods. My mother went down the conventional route and it killed her. There is someone on this forum who is big on alternative cancer fighting methods called Dquixote1217 who runs a website about it. If you have not already seen his website it might be worth you messaging him for a link to his website. He posted just below this message.
If you have not looked at Iridology then it might be worth you looking at it to see if it gives any information that might be helpful. The ascending colon can affect the right breast and so can suppressing the expression of sadness in some people which as a consequence affects the nerve impulses to the colon and can cause impactions on the bowel wall. My mother had that. She did go once to colonic irrigation but did not stick at it. That affects the normal immune system function. Another thing to look for is a difference in the size of your breasts because breasts which are at risk of cancer are usually slightly smaller, one breast can be smaller than the other and possible colder due to reduced metabolism. The marking in the iris, a grey marking in the breast zone, affects the immune system regulation in the area and causes the immune system to not function as well as it should. That means that cancer cells are not corrected or destroyed. The colon can affect this. Black marks inside the colon are something to look for as they can indicate impactions which will affect the function of the associated area. https://cdn.naturalhealthcourses.com/wp-content/uploads/2015/10/SNHS-iridology-6.jpg
My thoughts on cancer are that it is promoted my failure to sufficiently methylate which prevents the development of cancer. Methylation begins in the stomach and very common stomach infections badly affect the bodies ability to carry out this important function. These infections, like many now, are extremely resistant. If you have not done so then it would be worth checking your stomach acid to make sure that your stomach can produce sufficient stomach acid. There is a simple test with sodium bicarbonate which can give an idea of whether there is a problem.
