Is cancer primarily genetic or is it primarily environmental? - tonsillar cancer pictures
If the cancer develops, it was inevitable, because their genes? And on environmental factors had to "click"?
If my father had cancer of the tonsils, which can have me, later in life?
Some types of hereditary cancer more than others?
Tonsillar Cancer Pictures Is Cancer Primarily Genetic Or Is It Primarily Environmental?

There are epigenetics, genetics, in some cases caused by environmental factors.

There are several factors that could cause a genetic predisposition to receive certain types of cancer. This means that people have a certain genetic marker for increased incidence of cancer, whose members has a population of these markers.
But envirnonment also plays a role in cancer, it seems a combination of factors, including (but not limited to) genetics and environment.
Answer to the question for you, but should ask whether your father smokes or smoked, and then not / is it?
The genetic changes that are to the development of prostate cancer and causes of the clinical course of the disease from bad. In this case, we have shown comparative genomic hybridization (CGH) to changes in the DNA sequence number, it's all chromosomes in 31 free primary education and 9 prostate cancer recurring copy. The aim was to identify chromosomal regions important genes for the development of prostate cancer and to identify genetic markers of tumor progression. CGH analysis showed that 74% of cancer cases primary changes in DNA sequence copy number shown. Losses were 5 times more common than gains, and most commonly affects 8p (32%), 13q (32%), 6q (22%), 16q (19%), 18q (19%) and 9p (16%). Studies of allelic loss with 5 polymorphic microsatellite markers for the 4 different chromosomes were carried out 13 samples and showed a 76% concordance with CGH results. Local recurrence, which was developed during endocrine therapy, it gains u0026lt significantly (P \\ \\ \\ \\ \\ \\ \\ \\; 0.001) and loss (P \\ \\ \\ \\ \\ \\ \\ \\ u0026lt, 0.05) of DNA sequences in primary tumorsRS, with gains of 8q (found in 89% of repetition, as compared to 6% of primary tumors), X (56% vs. 0%) and 7 (56% versus 10%) and loss of 8p (78% vs. 32%), but most often involved. In conclusion, our results show that genetic changes in CGH, losses of several chromosomal regions in common primary tumors, suggesting that the inactivation of tumor suppressor genes in these sites during deletional chromosome is likely that the basic development of cancer of the prostate. Moreover, the pattern of genetic changes suggests an increase in recurrent tumors with a frequency of 7, 8q seen, and X, which can have the progression of prostate cancer and development of hormone-independent growth of a different genetic basis. These chromosomal aberrations may be useful as a diagnostic marker for the progression of prostate cancer
One thing I learned is in genetics, that some scientists believe that it is a marker of cancer in certain diseases such as lung cancer or breast cancer. At birth, you may 3 have 5 markers for lung cancer. The environment could contribute to a scoreboard, and smoking can contribute to a scoreboard, leading to cancer. So I guess I believe that cancer in the artificial factors of environment and heredity.
If your father has cancer of the tonsils, it can be less likely that you have the same type of cancer, then there is a common form of cancer.
For your last question, yes - some types of hereditary cancers are better than others. Breast and prostate cancer is well known that in the families, while the melanoma (skin cancer) Arent same all inherited at least consider the approval of the genes set the tone of the skin.
I hope that answers your questions:)
