<s>[INST] Hi there. Two weeks ago following a fnb in April, i had a lumpectomy and snb. They insist upon 6-7 weeks of radiation. I ve gone macrobiotic and am willing to consider different healthy options but I m curious to know if radiation therapy legally requires 4 X-rays a week just to check positioning ( no thyroid protection, etc) and if does more harm than good. And isn t proton therapy the way to go if you do it? I don t want to radiate my heart. Thank you. [/INST] Hi, dearI have gone through your question. I can understand your concern. Radiotherapy depends on type and stage of cancer.  Please give me your detail report regarding exact site, type and stage of cancer so that I can help you further. Thanks for using health care magic. Wish you a very good health. </s>
