Hi. I understand and want to advise you on how to deal with psychological problems. And you have them if you are afraid the diet will not help you lose weight. Cancer is not the only reason people lose weight. Many people lose weight after chemotherapy because of diet and sports. And if you have had all the tumor markers tested, including rm1, you should be sure you have no barriers to losing weight. Light cell carcinoma is not as dangerous as other cancers. You don't have to worry about your health because your health is fine. The problem is your fears.
