a doctor confirmed what this is
I HAD A SPECIALIST CONFIRM WHAT THIS WAS.
I passed the exact same looking thing and had multiple doctors examine what it could be. We then sent it off to a pathologist to do a specialized lab test to determine what it's made up of.
The outcome:
This is a concentration of fat and mucus!
I passed another one the next day (today) and have stage four pancreatic cancer.
The doctors told me last month that I have a month to live. Since switching my diet to Gerson and becoming completely plantbased my my tumour markers have gone from 50,000 to 10,000 and now to 1,200!
Hope this helps clarify this thread since many of the responses have no pathological testing done which makes it impossible to know what it might be.
Note that my egg looking thing could be different than someone else's but if you want to know for sure what it is then bring it into your doctor and request that a pathologist examine it.
