Worried about recurrence being cancer

It is always a good thing to follow up patients some years after their myotomy, because sometimes the condition is not always as stable as it should be. So I think you should try to get a reassessment of your achalasia. It is much more likely that it is a development of achalasia requiring, perhaps, some revision of the surgery or some other procedure, rather than cancer. Stress does increase the tension and potential swallowing difficulties even after a myotomy. But it is inevitable that you will have an endoscopy and this will check on the potential cancer aspect.There is a potential for some with achalasia of additional exposure to stomach acid that might create an extra Barrett's oesophagus / precursor to cancer risk, but I do not think that the risk of cancer with achalasia is anything other than low. Achalasia is a lot rarer than oesophageal cancer, and there must inevitably be somebody somewhere that has both, but I would really take things at face value and think in terms of needing further achalasia assessment. Unfortunately the system is not as good as it should be in reviewing achalasia treatment in the longer term.Swallowing difficulties should man that the system gives you an endoscopy appointment with some urgency, and quoting the cancer risk might speed things up a bit. But do not get this fear out of proportion.
