In many cases, the central act of negligence has involved an allegation of delay in a timely diagnosis of the cancer and thus timely treatment (either by way of chemotherapy, radiotherapy or surgery) has been delayed with the result that the prognosis for potential treatment and survival has been worsened or more radical invasive treatment has become necessary.
Often, the delay in proper diagnosis can result from a failure to carry out, properly analyse and react to abnormal blood tests. Failure to perform scans or X-rays, failure to properly read/ interpret such scans or X-rays or failure to perform core biopsies. Sometimes the negligence can involve poorly performed surgery. Less often medication or dosage errors occur so that the patient receives an excess or too little of a drug or radiation with adverse effects.
