<s>[INST] I am being evaluated for breast cancer and will be undergoing a PET Scan. My lymph nodes under my left arm/breast is 4 CM s. I have developed a lump much larger than a pea under my skin on the very end of my right clavicle.Some of my blood test results are at the the very end of the normal range; 2 show high: AST @ 47 U/L, and; GGTP @97 U/L. I have had cancer previously: Endometrial Wall in 2012; pre-cancerous stomach cancer cells 2012 (I have been bleeding profusely rectally every month or so); malignant cancer left hand 2013. Cancer is more than prevalent in my family. My 24 year old daughter has lymphoma. Can you shed some light on any of this for me?????? [/INST] HIWell come to HCMIf there is strong family history of malignancy and even you have some malignancy, though it is not being given any concrete evidence of this, still if you are having some malignancy then chances of hereditary increases to some extant, may be genetic in origin, hope this information helps, take care. </s>
