Cancer has hereditary influence in 5% to 10% of cases

Cancer has hereditary influence in 5% to 10% of cases

All cancers are caused by some influence on the genes of cells in some part of the body. This does not mean that this change is hereditary.

Cancer can be classified as sporadic or hereditary. Sporadic cancer comprises most cases of cancer and occurs at random, with no relation to family groups. On the other hand, hereditary cancer is characterized by genetically defined syndromes, producing a high risk of developing cancer. It is estimated that it accounts for an average of 5% to 10% of the occurrences of some types of cancer in the population.

In the case of sporadic cancer, the vast majority of cases are a ratio of acquired cell genes over of life and were not inherited (passed from parents to children).

In the case of hereditary cancer, the tumors most frequently associated with inherited genetic disorders are: breast cancer, colon and rectum cancer, ovarian cancer and thyroid cancer. It is important to remember, however, that not every individual who inherits a genetic predisposition will develop cancer.

Genetic testing now allows the identification of mutations in the genes associated with hereditary breast, ovarian and intestinal cancer. Genetic testing must be done jointly by the oncologist and / or a professional who specializes in genetic counseling.

If genetic testing is not possible, the oncologist can use some factors related to the patient the most important family history), tumor, and degree of kinship to predict which conduct would have the best chance of preventing the onset of a tumor in a particular relative.


New studies for the treatment of xerostomia

New studies for the treatment of xerostomia

Dry mouth can be a side effect of cancer treatments, since radiation can damage the salivary glands and impair the production of saliva. US Dental and Craniofacial Surveys believe they can develop a way to repair and regenerate the salivary glands and resolve that problem once and for all. Dr. Matthew Hoffman leads the Institute's Matrix and Morphogenesis department and is senior researcher on this salivary gland regeneration project.
