Growing and multiplying lumps behind BOTH knees - Synovial Sarcoma?
I'm a 25, almost 26 year old male. July 13th I discovered a small, soft, and some what movable lump behind my right knee. I also found at least one smaller lump behind my left knee. I saw the doctor for them about a week or two later and they said that I probably always had them and just noticed them now. They also thought I was overreacting because I had a testicle removed this summer for testicular cancer, it was very minor and I didn't have to do any treatment.
I tried to forget about the lumps behind my knees but they have continued to grow and multiply. As it stand today I have all sorts of fatty lumps behind my knees and can feel them starting to develop all the way up my hamstring. They are even starting to bother me when I run and sometimes when I walk to class. Most of the lumps feel like soft round fruit snacks or mike and ike candies. Directly behind my knee, I think it's called the knee cavity, you can feel a lot of these fatty lumps, almost like they are starting to accumulate on top of each other. I'm not sure if they are connected or just very close together.
I'm probably going to schedule another doctors appointment in the next couple of weeks.
What I'm wondering is does this sound like cancer, specifically synovial sarcoma? I know synovial sarcoma is extremely rare, but the fact i'm the exact age and gender of the average synovial sarcoma patient makes me nervous. Synovial Sarcoma is supposed to be large slow growing tumors, not lots of smaller tumors growing together, is that correct? Also, it seems pretty much impossible for cancer to develop behind both knees at the same time.
On top of all of this I have had a cough for that last month or more and it won't go away. I doubt that it's connected but it just makes me wonder.
I'm hoping there is a more reasonable explanation for these lumps growing and multiplying so fast.
Any information/input would be greatly appreciated!
