cancer are the tenth leading cause of death in US. Although brain cancer in pediatrics is rare. However‚ the number of new cases are increasing (12.7%) aged <20 years [1]. Glioblastoma Multiforme (GBM) is a malignant tumor which originates from astrocytes. It is a rapid growing tumor that affects the nervous system including the brain and the spinal cord [2]. As the years progress‚ the incidence of GBM increases due to different risk factors like age or race‚ which is associated with poor prognosis

Introduction Astrocytoma is a type of brain cancer. Astrocytomas are tumors that develop from star-shaped cells called astrocytes. Astrocytes are a type of brain cell that normally help to provide nutrition‚ oxygen‚ and structural support to the brain tissue. Astrocytomas may appear in different parts of the brain and nervous system. What are the causes? A tumor is formed when astrocytes grow into a mass of tissue. The exact cause of why the normal brain cells grow into a mass of tissue is not known

both lungs. These cells do not create healthy lung tissue‚ they divide immediately‚ forming tumors. As tumors grow and reproduce‚ they keep the lungs from being able to give oxygen to the bloodstream. Tumors that stay in one area and do not spread are called benign tumors. Tumors that spread to other organs‚ either through the bloodstream

diagnosed in children aged 1 - 2 years. Treatment Treatment options depend on the size and location of the tumor. •Small tumors may be treated by laser surgery or cryotherapy. •Radiation is used for both local tumor and for larger tumors. •Chemotherapy may be needed if the tumor has spread beyond the eye. The eye may need to be removed (a procedure called enucleation) if the tumor does not respond to other treatments. In some cases‚ it may be the first treatment. Retinoblastoma is curable

metastatic breast cancer and toxic side effects of currently available treatments necessitate the development of effective tumor-selective therapies. Neural stem cells (NSCs) possess inherent tumor tropic properties that enable them to overcome many obstacles of drug delivery that limit effective chemotherapy strategies for breast cancer. We report that increased NSC tropism to breast tumor cell lines is strongly correlated with the invasiveness of cancer cells. Interleukin 6 (IL-6) was identified as a major

(1 point) Both stage I and stage IV lung cancer is presented with cellular differentiation‚ loss of normal tissue structure‚ as well as irregular size and shape of the nucleus. Normal cells are able to divide and die cancer cells are pile up on top of each other forming a tumor. The staging and grading of cancer depends on

established rules for prevention. The ACS recommends that women age twenty and older perform monthly breast self-exams‚ and it also suggests clinical examinations every three years (ACS Breast). Mammography is also a wonderful tool for detecting tumors; however‚ there is conflicting data on when and how often women should have mammograms. What is known is that mammography is the best way to determine if a palpable lump is actually cancerous or not. Treatment methods for breast cancer can be lumped

Thyroid Cancer Thyroid cancer is a cancerous tumor or growth located within the thyroid gland.Thyroid cancer is the most common endocrine cancer. Thyroid cancer is one of the few cancers that has increased in incidence rates over recent years. It occurs in all age groups from children through seniors. The American Cancer Society estimates that there will be about 62‚450 new cases of thyroid cancer in the U.S. in an average year. Of these new cases‚ about 47‚230 will occur in women and about
