I am 75 years old mail suffering from secondary metastatic lung lesions and CA 19.9 is 740. I had 12 doses of chemo but the problem is not completely cured. Since it is told that frozen lemon helps in controlling cancer I want to know how much frozen lemon shall I take for better result per day and also whether I can take it in water because vegetables etc. Can not accommodate much. Shall be grateful for your advise.
