Tumor

Tumors and tumor-like lesions usually been discussed in a large category, because their appearances sometimes are similar and make differential diagnosis extremely difficult. But tumors are non-neoplastic lesions, while tumor-like lesions are not, therefore, treatment and prognosis of these two groups of disorders are usually different. The incidences of tumors and tumor-like lesions have big differences in literature, this may due to the classification of benign, malignant and non-neoplastic conditions

Genetic and phenotypic variation is observed between tumors of different tissue and cell types which mainly due to tumor heterogeneity. Heterogeneity is therefore as an important feature of malignant tumor in diverse genetic backgrounds, pathological patterns, differentiation stages, genetic mutation spectrum, transcriptomics and proteomics gene expression profile, et al. It indicates the high complexity and diversity in cancer progression. Tumor heterogeneity and drug resistance are great challenges

medical conditions tumors an usually refers to a process that's not especially dangerous. For instance uterine fibroid are common benign tumors. Benign is not cancerous, will not cause death. There are different types of benign tumors the most frequent tumor in women is perimenopausal. The benign tumor can be deadly if it grows in an enclosed space such as the skull, or in regions of the body where their presence can damage vital organs they can be dangerous. Malignant tumors are cancerous cells

systematic classification of tumors, there is more than one adopted scheme. Some classification schemes are based on the site of origin of the tumor i.e. the cell or tissue from which a tumor arises, some on their microscopic appearance while others on the genetic defects found in their cells. However, none of these adopted schemes are followed with rigid logic or consistency and there are present a number of exceptions to them. These classification schemes help categorize tumors keeping in mind their characteristic

Brain tumor is a congregation or growth of abnormal cells in the brain. There are many different types of brain tumors exist. Some brain tumors are benign and some are malignant (cancer). Brain tumors can start in the brain, or cancer can start in other parts of the body and spread to the brain. Most benign brain tumors do not contain cancer cells. Usually benign tumors can be removed and less relapse. The boundary of benign is usually clear, and the cells of benign tumors do not invade surrounding

Brain tumors are devastating depending on their malignancy and also their propensity to cause neurological deficits which may cause permanent disability. Malignant brain tumors can occur at all ages [1-2] and are associated with poor prognosis. Surgery forms the mainstay of treatment for brain tumors [2-5]. It is well known that significant tumor decompression is associated with a relatively favourable prognosis [6-10]. An important challenge in brain tumor surgery is the accurate recognition of

Tumor marker are substances that are produced by cancer to make a tumor found in your blood. They are produced in a much higher cancer level. It could be found in blood, urine, tumor tissues or other tissues if the patient have cancer. Tumor markers are proteins. Most are associated with one cancer. There is a bone test. A bone test when they determine if your bones are damaged either from cancer or some other cause. The scan will detect if you have cancer in your bones. People don’t usually have

and novelist. Widely known by most people, brain tumors affect lives everyday. The average person does not know the types of tumors, factors contributing to the location of the tumor, and the symptoms a person may have when they have a tumor. Primary and secondary brain tumors make up the two basic groups of tumors (1 “Brain”). Primary brain tumors originate in the central nervous system,

tumors are treated but if surgery is not a viable treatment radiation can also be used. Schwannomas are most commonly non-cancerous and begin in the hearing nerve. The hearing nerve can also be called the acoustic nerve, 8th cranial nerve, or the vestibulocochlear nerve. For the most part, this type of tumor is found in between the cerebellum and the pons at an angle. This type of tumor exhibits slow growth as these tumors slowly grow they move nerve fibers which can cause complications. Furthermore

TUMOR A tumor, also known as a neoplasm, is an abnormal mass of tissue which may be solid or fluid-filled. A tumor does not mean cancer - tumors can be benign (not cancerous), pre-malignant (pre-cancerous), or malignant (cancerous). There are many different types of tumors and a variety of names for them - their names usually reflect their shape and the kind of tissue they appear in. A tumor is a kind of lump or swelling, it does not necessarily pose a health threat. Tumor are not necessarily cancerous
