[|Human|] My husband was diagnosed with multiple myeloma 10 years ago and went into remission after 2 stem cell transplants. Also has parkinsons and in past 10 years has had small lung cancer, prostate and bladder cancer. Myeloma is back and he has chosen not to be treated due to all the other issues. Esophagus is only 5 mm wide and has trouble swallowing. Gastrologist has run several tests and thinks stricture is caused by gerd (never has seem to have it much) or radiation of the lung. Says not Parkinsons. Could it be because of the myeloma? In a couple days, he s going to use a pediatric scope and try to dilate to about 9mm. Should he do a biopsy--says doesn t look like cancer.
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. He had multiple myeloma.  It was treated by two stem cell transplantation.  Now he has lung, prostate, and bladder cancer.  His esophageal stricture may be due to some metastatic cancer or fibrosis. He should go for biopsy once to search the cause. Then he should take treatment accordingly. Dilatation of esophagus stricture by pediatric scope is helpful to remove some obstruction. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
