My father is a multiple myeloma patient. It's been 4 years now. He faced a relapse in the year 2016. Most of the chemotherapies are not working since January 2018. What can be done at this particular stage? Right now his blood currents are very low. So currently he is on supportive care like blood and platelet transfusions every week. We want to consult a doctor for second opinion. Can anyone suggest?
