Can A Benign Complex Cyst Of The Kidney Turn Cancerous
Stop worrying: This may be a little atherosclerotic aneurysm or a real epithelial cyst or calyceal diverticulum that's undergone dystrophic calcification. Unless the radiologist has expressed concern, I'd forget about it. Cancers arise from situations in which there's honest-to-goodness genetic damage and/or massive cell turnover. Neither's happening in a calcified cyst. ...Read more
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
I have a renal lower poll cyst on my kidney and i want to know if it is always cancerous what are the symptoms of the cyst
How common are "a typical simple kidney cysts"mine is 1cm?&what is the % of them being cancerous or become cancerous?&for how long should I follow it?
Radiologic: Suspicious for malignancy if cyst appears irregular, if there are thick septations within cyst, calcifications, irregularities, polypoid or solid elements within cyst wall or septations. If complex cuts appears to be enlarging. Should be confirmed by ct with IV contrast if diagnosis is by ultrasound. Also needs 2b followed by serial ultrasound if early intervention is avoided. ...Read moreSee 1 more doctor answer
If bosniak iif complex kidney cysts have a risk of being cancerous (up to 25%?) then why don't dr's remove it right away? Couldn't the cancer spread?
Not neccessary. : Bosniak iif cysts have low risk of progression, and can be stable up to more than 5 years without neoplasm progression, thus can be safely monitored. Retrospective study showed no patients developed locally advanced or metastatic disease from a bosniak iif. ...Read more
If a 1cm complex kidney cyst has been stable in size for 4 months, what are the chances it is cancer and is it possible for it to spread at this size?
Renal cyst: The fact that it is small and stable after 4 months is a good sign. However another renal ultrasound should be done in 6 months to look for growth or change in structure. There is an increased risk of malignancy with a complex cyst and it should be watched closely ...Read more
I had bladder cancer 10 yrs ago. Simple cyst in left kidney was 3mm, now 8mm and read as complex. What is the probability of malignancy?
Possible.: Difficult to give you probability statistics in this setting, but any complex cyst requires close monitoring. With your history of bladder cancer, though, i encourage you to follow up with your urologist for his/her opinion. Malignancy unfortunately is not out of the question, but would be much easier to manage sooner rather than waiting until later. Best of luck to you. ...Read moreSee 1 more doctor answer
High attenuation cyst on kidney, approximately 3cm. Erthryopoietin elevated and WBC, RBC and hemaocrit elevated though not drastically. Cancer?
Bright cyst on ct: Usually a high attenuating cyst means the cyst is bright on a CT scan. While malignancy is in the differential diagnosis there are benign causes as well, such as a hemorrhagic cyst (a cyst with blood in it). Usually such findings are followed up with additional imaging studies for better characterization and interval growth before proceeding to biopsy or resection. ...Read more
Can there be a cyst and a exophytic solid mass lesion on a kidney? are the thge same? does the solid mass indicate cancer?
Need followup: Renal cysts are common. The majority are benign. Cysts can also be assoicated with malignancies and some malignancies have cystic areas. A solid exophytic mass may be more worrisome. YOu need a further workup and you may need a biopsy or surrgical resection to know for sure. Discuss imaging and surgical options with your doctors. ...Read more
What is exophytic renal cysts? My husband has one that is measured 8mm. Could it be a precursor to kidney cancer?
Unlikely: Exophytic renal cysts are simply cysts that extend outside the kidney capsule. You can envision a "pimple" on the surface of the kidney. Endophytic cysts are those that are buried within the kidney cortex. The 8 mm cyst is very small and difficult to characterize on noncontrast imaging. However, such a small lesion without complex features is highly unlikely to be cancerous. May deserve followup. ...Read moreSee 2 more doctor answers
A cyst is a structure or mass that consists of a cellular lined sac. It is typically filled with fluid but may be filled with solid material. It can be congenital, traumatic, or acquired. They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more
The kidneys are paired organs that lie on either side of the vertebral column. Part of their critical functions include the excretion of urine and removal of nitrogenous wastes products from the blood. They regulate acid-base, electrolyte, fluid balance and blood pressure. Through hormonal signals, the kidneys control the ...Read more
