I am 29yrs old female.not sx earlier with fnac in nov'08 and in feb'08. dx with metastatic breast cancer.biggest tumor of size 52cmx 43 cm.agrees with core biopsy.The pet ct scan said'no significant lymph node involvement'.3 axilliary and mammary and pulmonary nodes were detected with sizes from 1 cm to 1.3 cm.But the report said 'extensive metastasis'.
1.What does this mean?
Also tested triple negative for ER,PR and HER Neu.
2.Can the tumor be metatstatic and grow fast even if All three receptors are negative?
3.After two cycles of chemo with cyclophosphamide, docetaxal and doxorubicin, th etumor has shrinked to less than 1 cm size. Is the treatment effective?
