Monitor Your Kidneys
TSC kidney tumors are benign and can grow rapidly. These kidney tumors are called renal angiomyolipomas or sometimes AMLs for short. They grow an average of 1.25 cm/year, which sounds like a little but is actually a lot. Most of the time, people with kidney tumors do not even know they have them because they usually don’t cause any pain or discomfort.
Experts agree that when tumors reach 4 cm or more in length, they can cause serious harm by rupturing (hemorrhaging). Sometimes when the tumors are that large, they can cause pain or tenderness in your lower back . Often the pain feels like it moves to the side or groin area.
If these kidney tumors rupture, they can cause life-threatening bleeding and require emergency surgery. Because of this, it is important for you to get regular scans and talk with your doctor regularly to understand if this is a risk for you.
The more you communicate with your doctor, the more you can take control of your tumors.
The Lifetime Risk of Hemorrhage From These Tumors Is Between 25% and 50%
