Most are non-infectious, although there are some non-communicable infectious diseases, such as parasitic diseases in which the parasite's life cycle does not include direct host-to-host transmission. The four main NCDs that are the leading causes of death globally are cardiovascular disease , cancer , chronic respiratory diseases , and diabetes .
Signs and symptoms are not mutually exclusive, for example a subjective feeling of fever can be noted as sign by using a thermometer that registers a high reading. [7] Because many symptoms of cancer are gradual in onset and general in nature, cancer screening (also called cancer surveillance) is a key public health priority. This may include ...
Because cancer is a class of diseases, [7] [253] it is unlikely that there will ever be a single "cure for cancer" any more than there will be a single treatment for all infectious diseases. [254] Angiogenesis inhibitors were once incorrectly thought to have potential as a "silver bullet" treatment applicable to many types of cancer. [255]
Non-communicable A non-communicable disease is a medical condition or disease that is non-transmissible. [34] Non-communicable diseases cannot be spread directly from one person to another. Heart disease and cancer are examples of non-communicable diseases in humans. [35]
Concerns were raised in 2011 that lifestyle diseases could soon have an impact on the workforce and the cost of health care. Treating these non-communicable diseases can be expensive. [3] It can be critical for the patient's health to receive primary prevention and identify early symptoms of these non-communicable diseases.
In the discussion of non-infectious diseases, a sporadic disease is a non-communicable disease (such as cancer) which occurs in people without any family history of that disease or without any inherited genetic predisposition for the disease (change in DNA which increases the risk of having that disease). [5] Sporadic non-infectious diseases ...
Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [ 1 ]
Worldwide, approximately 18% of cancer cases are related to infectious diseases. [9] [60] This proportion varies in different regions of the world from a high of 25% in Africa to less than 10% in the developed world. [9] Viruses are the usual infectious agents that cause cancer but bacteria and parasites also contribute. Infectious organisms ...
