One of the drawbacks of multiple myeloma are bone lesions. What that means to non-medical folk (like us) is that the plasma cells are reproducing too quickly in the bone marrow causing lesions (or holes for non-medical people) to form. More correctly they are called lytic lesions.
When you find one lesion on the skeletal system, the cancer is called plasmacytoma. When you find multiple lesions in the bones - it is called multiple myeloma. When Buffy went to the doctor to discuss the bone scan, she asked how many lesions Dad had. The doctor said too many to count! WHAT???? Basically his bones are in bad shape and he is in risk of breaking them quite easily.
The holes in his bones are different from osteoporosis. Instead of a weakening of the whole bone, or losing density - his just has random holes throughout his body - femur, skull, back, arms, pelvic bone, etc. Okay so I understand why the doctor didn't bother to count. Buffy said that when the doctor showed her the scan it looked like someone had taken a hole punch to his skeleton.
Treatment options are going to work on a few things:
1) Use medication to build up his bone strength.
2) Use radiation to shrink the 2 largest tumors - chest and pelvic bone.
3) Use medication to keep new tumors from forming and manage the ones he already has.
4) Try to control the overgrowth of plasma cells in his bone marrow.
If he does not respond as well as hoped to the treatment options above, he will opt to have a bone marrow transplant.
All in all, we still feel grateful. The doctor said that if you were going to have a stage 4 cancer - this was a great cancer to have. It responds well to treatment and the treatment is usually not chemotherapy. Lucky Dad?
