Is cancer genetic?

Some: Some cancers are genetic and run in families while others are sporadic and just randomly occur.

Only some: Many cancers occur sporadically. Breast cancer, ovarian cancer , familial colon adenomatosis polyposis , hereditary nonpolyposis colorectal cancer , multiple endocrine neoplasia ii, multiple endocrine neoplasia i, von hippel-lindau, ; li-fraumeni syndrome can be genetically linked.

Probably: We can identify many mutations which cause cancer or which predispose to cancer, such as BRCA 1 and 2, and provide invaluable susceptibility testing within a family. Now that we are getting down to recognizing the many dysfunctions which cause cancer, the mechanism in a non-classically genetic cancer may actually have an environmentally switched on genetic cause. There will likely be hundreds

Yes and no.: Cancer is all genetic in that is arises from genetic changes that lead to the uncontrolled growth of cells. But these changes arise from a complex interplay between our inherited genes and our environmental exposures. Some cancers are completely inherited (vhl kidney tumors), some appear mostly environmental (smoking, hpv, radiation, diet), but most are a combination of both influences.

Cancer: Many cancers occur sporadically. Breast cancer, ovarian cancer, retinoblastoma, familial colon adenomatosis polyposis , hereditary nonpolyposis colorectal cancer, multiple endocrine neoplasia ii, multiple endocrine neoplasia i, cowden's syndrome, familial melanoma, neurofibromatosis, von hippel-lindau, ; li-fraumeni syndrome can be genetically linked.
