Tumor

There are some significant differences between the two kinds of tumor. Each kind of tumor has its own characteristics. Benign tumors cannot spread out to other parts of the body because they are capsulated by a fibrous sheath of connective tissue. Therefore, they remain at their original sites. In contrast, malignant tumors (cancers) are not capsulated, so they have the ability to metastasize through blood and lymphatic vessels in a process called metastasis (1). The result of this process is new masses of the tumor will be created known as metastatic tumors. Another different characteristic is in their size and shape. Benign tumors are typically small and have smooth regular margins almost like normal cells. On the other hand, malignant tumors…

Enchondroma is a type of noncancerous bone tumor that begins in the cartilage. While these tumors are not frequently cancerous, they can still lead to deformity and fractures of large or small long bones. Although the cause of enchondromas are unknown, the tumors may be either from an overgrowth of cartilage that lines the ends of the bones or a persistent growth of original, embryonic cartilage. Enchondromas can affect anyone but specifically affects patients between the ages of 10 to 20 years…

A brain tumor is an abnormal growth of cells within the brain, which can be cancerous or non-cancerous (benign). It is generally caused by abnormal and uncontrolled cell division, normally either in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic blood vessels), in the cranial nerves (myelin-producing Schwann cells), in the brain envelopes (meninges), skull, pituitary and pineal gland, or spread from cancers primarily located in other organs…

Discussion Question #6 Article Summary My research paper is about a cytokine --- Tumor necrosis factor alpha, which is involved in systemic inflammation and is found in high concentration in patients diagnosed with autoimmune disorders. The article chosen describes the effects caused by a change in the level of cytokine Tumor necrosis factor-a (TNF-a). The cytokine TNF-a is a proinflammatory, recognized to encourage HIV-1 reproduction and is involved in the development of HIV-1 related…

In 2008, my grandmother began feeling especially tired, had trouble sleeping, often forgot information she knew by heart, and could not perform basic mental tasks, which are all symptoms of brain tumor (Liu et al., 2009). While she just overlooked it thinking she was stressed or exhausted, her second youngest son (the one who lives near her) advised her to go to the hospital to check her brain as a precautionary measurement. Thankfully, she listened and was diagnosed with a brain tumor that was…

The tumor development recognition framework comprises of two fundamental stages: preparing and discovery. The preparation stage is made out of two stages. In the first place, picture enrollment and division are led on the mind pictures. Second, tetrahedral cross sections are built for the portioned mind and tumors, individually. In our study, mind is sectioned by an edge identification. This technique synergistically consolidates the Active Appearance, Live-Wire, and GC strategies to exploit…

shape feature extraction of MRI brain tumor image retrieval. We used T1 weighted image of MRI brain tumor images. There are two modules: feature extraction process and classification. First, the shape features are extracted using techniques like Scale invariant feature transform (SIFT), Harris corner detection and Zernike moments. Second, the supervised learning algorithms like Deep neural network (DNN) and Extreme learning machine (ELM) are used to classify the brain tumor images. Experiments…

Brain tumors Sign and Symptoms Primary Alternative Names: Gliomas, Medulloblastomas Causes The causes of primary brain tumors are still unknown. Genetic factors and inherited disorders play a role in some types of brain tumors. Risk Factors Risk factors for brain tumors vary according to the type of tumor. Some types of tumors are more prevalent in men than in women. Some types of brain tumors usually occur in children, while others are more common in older people. Symptoms Brain tumors…

What are the different types of adult brain tumors and how are they caused? How are brain tumors treated? Brain tumors are treated by surgery or chemotherapy. Surgery is a very common treatment for primary brain tumors.Sometimes it takes a lot of time to fully take out a brain tumor because not all tumors can be fully removed. Which means that a surgeon will have to attempt to reduce the tumor’s size. How are brain tumors caused? Brain tumors are caused by some genetic diseases which put you…

in determining the response of brain tumors to chemotherapy, radiation, and surgery. Patients over sixty years old have a lower response rate and shorter duration of response than younger patients. Tumor cells from younger patients were sensitive to BCNU, but cells from older patients barely responded to the BCNU. Only a few studies evaluate age as a parameter of response. Older patients may have to take medicine due to chronic illnesses, and this means that there should be special attention to…
