Histone methyltransferases: regulation of transcription and contribution to 469 human disease. In particular, the relationship between cancer and aberrant hypermethylation of specic genome regions has attracted attention. The main difference between epigenetic abnormalities and genetic abnormalities, such as gene mutations, is that epigenetic changes are reversible and do not involve changes in base sequence, which suggests that gene re-expression is possible and that epigenetic data may lead to important molecular targets for treatment. In Japan, the number of women with endometrial cancer and the prevalence and mortality rate of this cancer continue to increase due to westernization of lifestyles and environmental T. Endometrial cancer currently accounts for approximately 40% of all cancers of the uterus and an increase in the total number of patients and the number of young women with this condition has been forecast.

Therefore cell division is part of the bodys natural maintenance and a prerequisite for life generic luvox 100mg amex. Benign tumours Normal cells usually divide without problems discount 100 mg luvox visa, but sometimes they divide too much. If you take a tissue sample of the tumour and look at the cells in a microscope, they still look normal only there are too many of them. Benign tumours do not spread to other parts of the body and should not be confused with cancer. As a consequence of genetic degeneration mutation the cells have divided too much and formed a tumour, a hyperplasia in Latin. In addition there is a more serious defect in the genes of the cell another mutation that changes its shape and the way it looks. Spreading of cancer (metastases) Normal cells are destroyed if they are diseased, but cancer cells go on living and generating new cells. Once the cancer tumour penetrates the surrounding tissue and spreads, it is a case of invasive cancer. If the cancer tumour has not grown through the surrounding tissue, it is called cancer in situ (on the spot). If the cancer cells reach the blood or lymph ducts, the disease may move further around in the body and settle and grow in organs completely separate from the organs in the proximity of the place of origin of the cancer. Cancer cells that become disconnected and settle somewhere else in the body are called metastases (Greek for removal). If breast cancer, for instance, spreads to bones and liver, this is due to metastasising. Main groups of types of cancer Cancer may arise in almost all cells of the body, but in some places more often than others. Often a type of cancer is named after the organ in which it is situated, for instance breast cancer or lung cancer. Medical information In order for a cancer disease to be recognised on the basis of the list, a medical doctor must have made a diagnosis consistent with one of the cancer diseases on the list (Group K). It is up to the National Board of Industrial Injuries to decide if the disease/diagnosis is consistent with a disease on the list or if there may be grounds for submitting the claim to the Occupational Diseases Committee with a view to recognition not based on the list. The cancer diagnosis must, as far as possible, be made in a microscopy test where there is a positive find of malign cell degeneration (malign tumour). In such cases a clinical image and a description of the aetiology in the hospital records may contribute to making the diagnosis seem likely. The National Board of Industrial Injuries cannot demand microscopic examinations or other examinations requiring invasive intervention. In the event of death we furthermore obtain a death certificate as well as any autopsy report if such a report is available. The National Board of Industrial Injuries may request an autopsy report in cases of doubt if we become aware, immediately after the death of the injured person, that the death may be work-related. In that case a post-mortem examination requires the consent of the surviving relatives. After receiving the claim we gather the necessary additional information for the further processing of the claim. If the injured person has not yet been examined in a clinic of occupational medicine, we will in most cases ask a clinic near the injured person to issue a medical specialists certificate. The medical certificate will include information of the concrete working conditions and exposures in the workplace as well as a thorough description of the disease. The medical certificate will include the following disease-related information 1. A detailed occupational history (work description) To the extent we find it necessary in order to get a better overview of the disease, we may also get a medical specialists certificate from a doctor who is specialised in the concrete disease area. This may for instance be a certificate from a pulmonary specialist, or perhaps a specialist of radiology, if the claim pertains to the lung or the pulmonary pleura. In the event of very complex cancer diseases we will in a few cases get a special assessment from a particularly specialised doctor that may give an overview of the medical knowledge in the field and a medical assessment of the likelihood of a correlation between the disease and the exposures described in the concrete case. Primary or secondary cancer In each case we decide if the reported disease is a primary or secondary cancer disease. In a few cases the first reported cancer disease turns out to be a secondary form of cancer that has come about as a consequence of spreading of the original cancer (metastases). In our assessment of whether the claim qualifies for recognition we only decide on the primary cancer disease as it is only this disease that may be work-related. Secondary cancer forms are a result of the general spreading of the cancer in the body (metastasising) and do not in themselves have any relation to specific exposures at work. Latency time 267 The development of cancer occurs through a slow process, which means that the disease often only breaks out many years after the carcinogenic exposures, depending on the type and extent of the exposure and the specific form of cancer. The time that passes from the exposure till the onset of the disease is called the latency time. The typically long latency time for cancer diseases means that, before it can be said that there is a medical correlation between disease and exposure, a number of years must have passed from the exposure till the onset of the disease. If the cancer disease breaks out within a short period of time (months or a few years) after the exposure to otherwise relevant carcinogens, this would be an argument against the disease having come about due to such exposures at work.

Four phases of medication clinical trialsa Phase I Phase I trials assess safety and toxicity of an experimental agent in healthy volunteers or sometimes in individuals with the medical condition of interest. Phase I trials are only conducted if there are adequate data from laboratory and animal studies to justify trying the experimental agent in humans. Phase I trials generally enroll a small number of research participants and last a relatively short period of time (weeks to months). They generally involve random assignment to these different groupsthus research participants do not get to choose which group they will be in. In addition, research participants and the researchers themselves are frequently not allowed to know which group they are in during the course of the triala research design aspect known as blinding or masking.
