Tumor markers Tumor markers are biochemical indicators that are used to detect or chek presence of cancers generaly. these biochemical indicators are abnormal molecules secreted by the tumor celssand they are included surface anitigens‚ cytoplasmic proteins‚ enzymes and hormones. These markers are measured from the serum and are used in screening tests of the population to evaluate presence of cancer. These markers are also important in supporting diagnosis of cancers. And also in addition they are

gland tumors are neoplastic tumors of the mammary glands. These tumors are more common in canine and feline female animals and rarely occur in large domestic animals. Mice are also affected by mammary gland tumors. Although the incidence of mammary gland tumors are more often seen in female canines than female felines‚ the malignancy rate is higher in felines. The cause of mammary gland tumors in mice can be from an oncornavirus (retrovirus). Hormones may be a cause of mammary gland tumors in canines

a mass of cells‚ called a tumor. Various types of tumors can grow in the appendix and result in cancer. To begin‚ carcinoid tumors are small tumors that show no symptoms and can commonly be treated before they grow. Another type of tumors‚ mucinous cystadenocarcinoma tumors produce a jelly like substance called mucin that causes abdominal pain. Colonic-type adenocarcinoma tumors often go unnoticed until they are found during surgery for appendicitis. These types of tumors are very rare and much more

Cancer is a perilous illness and is certainly not a joke‚ nor are brain tumors such as a brainstem glioma. The fatal disease mainly targets children from the ages of five to ten regardless of their medical history‚ gender‚ or race. Brainstem gliomas‚ like all cancer‚ does not affect just the diagnosed child‚ it is a disease

a quick and precise diagnoses of the patient’s illness. The bones‚ heart‚ and thyroid can easily be viewed or imaged with the use of radioisotopes in medicine. Additionally‚ in some cases radioisotopes can be used to treat diseased organs or even tumors. This treatment is expended in most forms of cancer. Over 10‚000 hospitals worldwide use radioisotopes in medicine. Approximately 90% of all procedures are for diagnoses. The most popular radioisotope for diagnoses is technetium-99‚ used for roughly

Astrocytes are responsible for protecting other nerve cells found within the brain and spinal cord and are known as glial cells and form tissue which is known as glial tissue. Tumors that arise from glial tissue‚ including astrocytomas‚ are collectively referred to as gliomas. They accounts for 35 to 50 percent of all tumors that are present in the brain and spinal cord. Astrocytoma is separated into two classification systems and into four different groups‚ which are determined by the histopathologic

collect multiple slice data at the same time‚ with PET has the most interest in cancer imaging. FDG-PET has been applied to accurate biopsy of infiltrative tumors‚ tumor grading‚ and prognostication. Brain tumors form a significant percentage of pediatric oncology. The use of FDG-PET in brain tumors have helped distinguish viable and recurrent tumors from post-therapeutic changes. These diagnostic images in technology also reveal disease sites that are not detected yet by conventional staging methods

A genetic disorder in where many soft fibrous swell and grows from nerves in the skin and also in other parts of the body. The tumors form in the issues and structures of the nervous system. Neurofibromatosis may also deal within bones‚ skins‚ muscles and connective tissues‚ the brain and visceral organs too. This genetic disorder is inherited from the parents that have neurofibromatosis. There is a possibility of fifty percent that the parents children ends up inheriting the gene or developing

cell phone for a decade don’t have different cancer rates than those who have not. Last year‚ a different study found no connection between cell phones and cancer. But it showed a possible connection between heavy phone usage and glioma‚ a brain tumor that is rare but deadly. However‚ this information was not enough to support the case. That study of over 14‚000 people in many countries‚ along with animal experiments‚ led to classifying electromagnetic energy from cell phones as possibly carcinogenic

magnetic field created in ways that allows for a high quality image to be generated (2). These images contrasts specific tissue and different anatomical structures. For example‚ MRI can reveal the gray and white matter in the brain‚ diagnose brain tumors and inflammation in certain body parts‚ and can create images of the spine‚ joints‚ abdomen‚ lungs--numerous parts of the body (2). . First‚ MRI relies heavily on electromagnetic energy‚
