Thalidomide was used on my second wife who had a very rare cancer. It stopped the blood supply to the tumors for 2 years, resulting in stopping the tumors growth, but it did not eliminate the cancer, The Doc tried her on a different promising medication that did not work and she eventually died after a 5 year fight. So in some cases Thalidomide is effective, it gave her an extra two years of life which was a blessing.
My first wife also died of cancer, she fought it for 4 years.
Two weeks ago my present wife has been diagnosed with CLL Leukemia. Fortunately it is a slow growth.
Merry Christmas my friends, hold your love ones close.
