Hi. I am 28 years old and I was diagnosed with malignant pilar tumor. The tumor was already removed last january 2019 by excision. After the operation, the biopsy result tells that the cancer cells has not spread near the area of the tumor.in this regards, I just want to ask if i'm already cancer free after the surgery? I still have doubts because I was advised to undergo radiotherapy even the biopsy result tells it's negative. I am ardently hoping for a positive response. Thank you!
