You won’t know if you have oesophageal cancer until your doctor has yarned with you, completed a physical examination and done some tests. The tests might include: a physical examination blood tests imaging tests like an ultrasound, a CT scan, an MRI scan or others to see what your insides look like an endoscopy, where a doctor put a long tube down your throat so they can look inside your oesophagus and stomach a biopsy, where a tiny bit of your oesophagus is removed during the endoscopy, and the doctors looks at it with a microscope.  Most people who have these tests find out they don’t have cancer. But it’s important to check.
