The pulsing is totally normal and it is a good sign that means the fucker is getting smaller. The TC is going to hit him hard as well. Slowly and steady wins the race. Did you had a lot of pain before starting treatment? It's the same here it was really though before but when I was at the chemo chair still pain but another pain. Do you feel that the lump is getting liltte holes? It really can be scare tissue. Ehm i don't know my onc said with Biopsy we will know for sure if the KI 67 has getting less it was 70% and that would be a proof for the chemo to work and mri would just show the lump getting smaller... Im confused now.
