That's a dictionary definition rather than a medical model. My previous comment stands - if Ulsterman is concerned that his employer may be less accommodating or flexible, he should challenge the OH doctor to amend his language in the report since there is no way he is in remission at this point.
From the Cancer Research UK website:
Cure or remission
These days, doctors are able to cure many cancers. But some cancers can come back many years after treatment. So you may find that your doctor is very unwilling to use the word 'cure', even though there is no sign that you have any cancer left. Doctors usually say that your cancer is in remission. This means that there is no sign of cancer in your body. If there are any cancer cells left:
- there are too few to find
- there are too few to cause any symptoms
- they are in an inactive state and are not growing
Doctors can't be sure that the cancer has completely gone after treatment. So they may suggest that you have some type of long term treatment, such as hormone therapy or a targeted cancer drug. Your doctor may call this adjuvant treatment. Adjuvant treatment can also be a course of chemotherapy or radiotherapy after surgery. The aim of this treatment is to try to prevent cancer from coming back.
It can be very difficult to live with the fact that your cancer may come back. Even if doctors tell you that they are 95% certain your cancer has gone for good, you may find it very upsetting that no one can say for sure that you're cured.
Some people find that they can't stop thinking about it even after the end of their treatment. You may feel a little frightened of planning anything in the future or you may feel sad or depressed.
For most people who are in this situation, each day lowers the risk of a recurrence. Most cancers that are going to come back will do so in the first 2 years or so after treatment. After 5 years, you are even less likely to get a recurrence. For some types of cancer, after 10 years your doctor may say that you are cured.
