Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. [3] [4] Cancer can be difficult to diagnose because its signs and symptoms are often nonspecific, meaning they may be general phenomena that do not point directly to a specific disease process.
It is often underdiagnosed due to variability in disease presentation, but 99% of patients report mucocutaneous symptoms by age 20–29. [2] Despite some considering it a primarily dermatologic condition, Cowden's syndrome is a multi-system disorder that also includes neurodevelopmental disorders such as macrocephaly .
An early warning system (EWS), sometimes called a between-the-flags or track-and-trigger chart, is a clinical tool used in healthcare to anticipate patient deterioration by measuring the cumulative variation in observations, most often being patient vital signs and level of consciousness. [1]
Five year survival rates of different cancer in the UK, 2009. The passing of the Cancer Act 1939 marked the political significance of cancer treatment. It envisaged a system of co-ordination of diagnosis and treatment under the control of County Councils and County Borough Councils which preceded the establishment of the National Health Service (NHS).
Symptomatic features of paraneoplastic syndrome cultivate in four ways: endocrine, neurological, mucocutaneous, and hematological.The most common presentation is a fever (release of endogenous pyrogens often related to lymphokines or tissue pyrogens), but the overall picture will often include several clinical cases observed which may specifically simulate more common benign conditions.
Pain and symptom management are an important part of care. [2] Palliative care is particularly important in people with advanced disease. [2] The chance of survival depends on the type of cancer and extent of disease at the start of treatment. [11] In children under 15 at diagnosis, the five-year survival rate in the developed world is on ...
A differential diagnosis is also commonly used within the field of psychiatry/psychology, where two different diagnoses can be attached to a patient who is exhibiting symptoms that could fit into either diagnosis. For example, a patient who has been diagnosed with bipolar disorder may also be given a differential diagnosis of borderline ...
In medicine (oncology and other fields), performance status is an attempt to quantify cancer patients' general well-being and activities of daily life. This measure is used to determine whether they can receive chemotherapy, whether dose adjustment is necessary, and as a measure for the required intensity of palliative care.
