My husband had squamous cell base of tongue 24 years ago. He not only had the chemo and radiation, but a radical neck dissection since it went into the lymph node. About 12 years ago, he started having problems speaking and eating and just last year had a G-tube inserted. As far as mucus, that in itself became a big problem and now more excessive to the point he feels (and sounds) like he is drowning and awakes him at night while sleeping. He is constantly spitting into a cup or tissue. He has tried using a nebulizer and also a suction machine, but it did not work. As a retired nurse, I am constantly researching and trying to keep up with anything new including clinical studies. Nothing helps as far as the recommended daily remedies. Unfortunately, I am told by his physicians that it will only get worse. Yes, the cancer went away, but the damage and quality of life has taken over.
