I was diagnosed almost one year ago - invasive ductal carcinoma, HR and PR positive and HER2 negative. I was 71 when diagnosed and am 72 now. I did hours and hours of research and I read a few books. I ultimately decided on having a partial mastectomy (took a piece about the size of a peach), but turned down the radiation and aromatase therapies because of the large number of serious side effects involved. I found a really good Naturopath and she is giving me supplements to deal with issues like the estrogen - but it only blocks the type of estrogen that feeds the cancer and not the types that foster bone growth etc. Also, she has me doing mistletoe injections that have been used in Europe for several years with great success for treating breast cancer and a couple of other cancers. On top of this I am taking Artemisinin pills that also target the cancer cells along with a number of other supplements, and working my diet towards vegan - maybe only 75% there so far. I have upped my exercise with walking, doing some weightlifting and I will soon be adding swimming. I am having little to no side effects and feel healthy. Two really good books I read were: "Chris Beat Cancer" by Chris Wark AND "Keep Your Breasts" by Susan Moss (I think you have to buy this second hand as I couldn't find new print ones - but a lot of choices second hand on Amazon etc.) I feel that you need to do as much research as you can, weigh in all the types of treatments that are offered whether conventional or alternative, and make a decision that you believe in for you. Believing in your treatment goes a long way in helping it to work. Also, I have many people praying for me, and I am sure that has contributed to my ongoing good health. Good luck to all - having cancer is quite a journey! 🙂
