I'm really scared that it could be cancer.

Female, 23years old 55kg soI had been feeling some discomfort in my calf, but I thought it was just a muscle strain. This month, I noticed that my leg was swollen and that it hurt when I walked for a long time.I went to a vascular doctor, who told me there was a mass. The next day, I saw a radiologist and had an ultrasound. He confirmed that there was a mass and said I needed an MRI. He told me that once I had the results, we would see what to do, and that if it was a cyst, it might just be drained with a needle.I went and had the MRI right away. They said the results would be ready in two days.
