All these possible factors involved in the development of cancer not only work together but can do so in a multistage process; meaning that different factors can influence carcinogenesis at different times but still in conjunction with each other. The development of colorectal cancer is an example of such a process that combines both oncogenes and tumor suppression genes acting at different times but influencing each other and contributing to the development of cancer. And since these are genetic influences, they can " sometimes appear to 'run in families..'," or be carried by members of the same family. ("Genetic Testing for Hereditary Cancer Syndromes") in fact, there are a number of types of cancers that seem to cluster in familial groups; like breast, ovarian, and prostate cancers.
Since certain types of cancers are caused by genetic factors that can be found in familial groups, members of these groups should be aware of the possibility of developing cancer. For instance, if several members of the same family develop the same type of cancer, or a rare type of cancer, there may be inheritance factors at play....
In fact, any type of cancer related problems within multiple members of the same family may be an indication of some type of familial genetic tendency toward cancer. With this in mind an individual who feels that their familial group may have a predisposition toward cancer may want to have regular cancer screenings, particularly for familial-linked cancers. Screening for cancer should involve a series of tests directed at the type of cancer that the individual's family exhibits and usually should begin at early adulthood. But it is vitally important that those between the ages of 35-50 be screened as this is the time when individuals are most susceptible to inherited cancers. Finally, if cancer is detected the individual should immediately seek out an appropriate treatment, one that is the least invasive but most effective possible.

Genetics and Pharmacology Drug metabolism in humans is an essential topic to understand if one is to go into the pharmaceutical industry. When an individual ingests antibiotics their body is already prepared with the proper enzymes and molecular processes that allow for the breakdown and the uptake of these drugs. Xenobiotics encompass any substance that is foreign to the body; antibiotics fall into this category (Katzung, Masters, & Trevor, 2012). These
Breast Cancer in Malaysia Breast cancer has turned out to be one of the most common cancers in women in almost every part of the world. Nonetheless, there is a noticeable geographical difference in the incidence and also the stage of presentation. It has ben documented to be uppermost in North Europe and North America, in-between in Mediterranean nations and South America, and not high at all in Asia and Africa
The subjects for the study were referred by local oncologists and to protect their rights they were provided with informed consent before participating. In other words, what would be studied and why was explained to them and they could then decide whether they wanted to participate or decline. There was no requirement to participate and patients could stop any time that they felt uncomfortable. It is vital that individuals who
Health Care (PHC) and Colorectal Cancer Authorities around the world have expressed the need for development of an incorporated health care system with augmented emphasis on primary health care, and integration of principles and practices of health promotion. Primary health can be defined as the care provided at the first point of contact with the health care system, the point at which health services are assembled and synchronized to promote
Breast Cancer How Genes Influence Breast Cancer Director of the National Cancer Institute How Genes Influence Breast Cancer Many environmental factors can affect a person's risk of breast cancer, but they are not the only issues to consider. Genetics also play a strong role in whether a person develops breast cancer or avoids it. A strong family history of the disease can predispose a person to breast cancer, but it is not a guarantee
Since the antigens are closely linked to race and ethnicity, it is much easier to find a biological match among people with similar ethnic and racial backgrounds than it is among any two randomly selected individuals. On the basis of tissue matching, organs from blacks will almost always go to blacks and organs from whites will almost always go to whites. Blacks, however, have a much higher incidence of
