I called my parents today. My dad is doing quite well. He has gone through chemo to treat his lymphoma, and is now scheduled to have a new scan to see how well the treatment has performed. I am hoping that it will be all clear so he can move on. There is however, a new problem. He has developed a heart murmur in the valve where blood from the lungs enters the heart. This valve is leaking and allowing some fluid to escape back into the lungs. Unfortunately this means open-heart surgery, tentatively scheduled for early March, and presumably contingent on the lymphoma being in remission.
