A medical professional treating you owes you a duty of care to prevent harm being suffered by you.
There are many different mistakes that may be made, which could lead to a “breach of duty of care” by a medical professional. To prove that negligence has occurred, it would need to be shown that the breach of duty of care caused you harm, that was otherwise avoidable.
Cases often involve a patient seeing their GP because they are worried about their symptoms, but the GP then fails to recognise that their symptom or collective symptoms are indicative of cancer, and an onward referral to an appropriate specialist is not made. This can lead to delays in diagnosis and treatment.
If you suspect that you have symptoms of any form of cancer, you should see you GP. If the GP is concerned, you should be referred to the appropriate specialist, and seen within two weeks.
