Post Cancer treatment severe atrophy of the limb

I was treated with chemo and radiation for Ewing Sarcoma at the age of 12, 26 years ago. The tumor was on the tibia right below the knee. Since then I the leg has atrophied to 50% of the size and has lost many functionalities. Some Dr.'s have attributed this to fibrosis of the veins. Qs.

1- Is there anyways to stop the atrophy?
2- Will exercise improve the limb or further accelerate the atrophy?
3- Is there any cosmetic suggestion for coping with the disfigurement?

Hi,
It is impossible to say with confidence the reason for the atrophy of the limb. However, it is reasonable to conclude that the sarcoma, or the treatment of the sarcoma, are likely to be in some way responsible.
Please consult a neurologist for advise.
All the best, and God Bless!
