with a brain tumor‚ it is a scary life-changing event. The brain is one of the most important vital organs‚ and if found with a brain tumor‚ go to the doctor for immediate help. The brain and spine make up the central nervous system or CNS. Where each vital function is controlled. So if you have a tumor in your CNS‚ it can effect everything you do like: your thought process‚ how you talk‚ and even how you can walk. There are two types of brain tumors‚ primary and secondary tumors. A primary

believe that Cellphones cause brain tumors? The issue defines that all phones may cause radiation to your brain which regular people or scientists believe otherwise. Always two different sides to the story just like this one. People even scientists know that maybe cell phones cause tumors. Radiation from your cell phone can cause cancer and the energy is a form of electromagnetic radiation. Many studies have examined people that do have different types of tumors if they’re are cell phone users. Cell

The Tumors Are all tumors dangers? A tumor is a mass of new tissue growth that doesn’t react to normal controls or the organizing influence of other tissues. It has no useful function in the body. This applies to both benign tumor and malignant tumor. Many people think that the types of tumors are similar. Actually benign tumor and malignant tumor are very different from each other in riskiness‚ spreading way‚ location‚ examination‚ treatment‚ recovery and effectiveness to the body.

Anal tumor is a standout amongst the most aggressive variety of cancer‚ particularly if not detected in its initial stages. Its uncomplimentary location‚ which makes it an unthinkable for a large number of people‚ is yet another reason behind why this tumor is frequently ignored. What Is Anal Tumor? Anal malignancy grows at the opening of the rectum (anus) from a lump which is made by the unusual and uncontrolled development of cells in the anus. Despite the fact that it’s rare‚ it’s often disregarded

CARDIAC TUMORS INTRODUCTION Cardiac tumours occur quite rarely‚ with metastatic neoplasms three times more prevalent than primary tumours. A large variety of benign and malignant tumours of the heart have been described. These tumors are found mainly in the heart‚ but can occur in the pericardium or the great arteries. Secondary cardiac involvement from malignant tumors of adjacent organs (lung‚ thymus) or from kidney (Wilms tumor) or liver‚ or even remote organs‚ are also seen. ANATOMY AND PHYSIOLOGY

Radiation therapy (RT) is an essential component in the interdisciplinary treatment of brain tumors. Independently of histology‚ radiation plays a central role and has shown to increase local tumor control. Developments in radiation oncology are always aiming at an increase precision of dose delivery: More conformal coverage of target volumes‚ steep dose gradients to surrounding tissues‚ and sparing of organs at risk (OAR). In photon therapy‚ based on 3D-RT‚ stereotactic radiotherapy was a big step

2: Using the Scientific Method Protocol: Background information: Tumor cells are cells that are able to divide and generate new cells at uncontrolled rates. Therefore‚ in a short amount of time‚ a single mutated tumor cell can produce many other tumor cells. These cells can eventually take over the human body‚ resulting in death. But‚ for these tumor cells to survive‚ they need nutrition and oxygen just like normal cells. Tumor cells are interesting in that they can release a substance – a protein

suggested the relationship between PRL and CNS tumors. Ciccarelli et al reported in 2001 that high PRL levels and increased PRL receptors were found in some of the patients with meningiomas and schwannoms‚ indicating that PRL might be involved in the growth of the two benign intracranial tumors [9]. The later study by Leães et al in 2007 showed that hyperprolactinemia‚ intracellular PRL and its receptor were common findings in patients with primary CNS tumors such as meningioma‚ glioblastoma‚ astrocytoma

Primary Source: Tumor Microenvironment Topic Summary Cancer has become one of the world’s leading trends in diseases‚ both in discussion and in medicinal related research. Major insights and discoveries within cellular biology can be accredited to the drive of understanding and curing cancer. The battle of cancer began to rise in public attention around the era of Henrietta Lacks‚ who provided the world’s first immortal cell line. Most research of the time‚ and even up to the past decade‚ was targeted
