Hello sir, My father was operated for nephrectomy due to kidney cancer in 2019. At present he is consulting for lung nodules. As per doctor's opinion we did a biopsy of nodules and the report concluded metastatic renal cell carcinoma in lungs. Previously from 2019 to 2021, he was taking homeopathic medicine and the sizes of nodes did not change much but in last 4 months after we stopped homeopathic it has doubled in size and number. Our doctor has advised immunotherapy or targeted therapy as the nodes are less than 18mm. So should we restart homeopathic or go with immunotherapy/targeted therapy? Our can we do both at a time?
