A cancer syndrome or family cancer syndrome is a genetic disorder in which inherited genetic mutations in one or more genes predisposes the affected individuals to the development of cancers and may also cause the early onset of these cancers. Although cancer syndromes exhibit an increased risk of cancer, the risk varies.
Ulceration can cause bleeding that can lead to symptoms such as coughing up blood (lung cancer), anemia or rectal bleeding (colon cancer), blood in the urine (bladder cancer), or abnormal vaginal bleeding (endometrial or cervical cancer). Although localized pain may occur in advanced cancer, the initial tumor is usually painless.
World-wide, liver cancer is the 4th most frequent cause of cancer mortality, causing 9% of all cancer mortality (total liver cancer deaths in 2015 being 810,500), and coming, in frequency, after lung, colorectal and stomach cancers. [34]
Tobacco smoke causes increased exogenous DNA damage, and this DNA damage is the likely cause of lung cancer due to smoking. Among the more than 5,000 compounds in tobacco smoke, the genotoxic DNA-damaging agents that occur both at the highest concentrations, and which have the strongest mutagenic effects are acrolein , formaldehyde ...
Some infectious agents are linked to increased risk of cancer in their host organisms. The articles in this category pertain to such infectious agents, the vaccines that prevent infection by these agents, the names of the cancers linked to, associated with, caused by and/or have an increased risk of developing from these infectious agents.
The causes listed are relatively immediate medical causes, but the ultimate cause of death might be described differently. For example, tobacco smoking often causes lung disease or cancer, and alcohol use disorder can cause liver failure or a motor vehicle accident.
The epidemiology of cancer is the study of the factors affecting cancer, as a way to infer possible trends and causes. The study of cancer epidemiology uses epidemiological methods to find the cause of cancer and to identify and develop improved treatments. This area of study must contend with problems of lead time bias and length time bias ...
The following is a list of cancer types. 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 ]
