Dear friend, welcome to HCM.
they report a small cyst
(fluid filled cavity) with a nodule (tumour)or debris in left kidney
upper end. which has grown in size from previous size in an older scan. a new tumorous growth in lower end also present.
the doctors would like to find out the exact characteristics of it and the surrounding structures to decide if it is benign or cancerous.
many may be non- cancerous/ infective cysts.
pl. await results. you may require a CT guided biopsy
by a urologist
take care and keep me posted on the site/ email about your progress.
Good luck !
