I have a small lump on the top of my left foot. I asked the doctor to take a look. He examined it and confirmed it to be a ganglion. It's not cancerous.
This is a definition taken from the eMedicine Health website.
A ganglion cyst is a tumor or swelling on top of a joint or the covering of a tendon (tissue that connects muscle to bone). It looks like a sac of liquid (cyst). Inside the cyst is a thick, sticky, clear, colorless, jellylike material. Depending on the size, cysts may feel firm or spongy.Interestingly enough, a ganglion cyst is also known as Bible cyst. And a treatment that is no longer advised is called the Bible therapy. That involves smashing the cyst with a book! Today, is is either left untouched, treated with aspiration (removing the fluid using a needle) or surgical removal.
So, I have a tumour but I'll be fine.
