Benign tumor

processes of the cell cycle, apoptosis, and die. When cancer cells cannot perform this process of dying they continue to rapidly grow and multiply. Eventually they become a large growth of cells also known as a tumor. When a tumor is not harmful it is called a “benign” tumor. When a tumor is harmful and cancerous it is considered “malignant”. From there the cancer is at stage 1 and will begin to spread through time. Moving its way through the stages and hopefully it has already been discovered…

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…

regional failure with or without distant metastasis. Recurrent tumors usually extensively damage surrounding tissue. In rNPC patients, physical status and immune system are generally poor because of prior treatment. A study of Lee from Hong Kong reported that 52% of patients developed rNPC within 2 years, and 39%, within 2–5 years6. Precision imaging was role to support the diagnosis of…

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 are…

modality used for detection of brain tumor and breast cancer. A forward model design depicts the placement of laser source and photo-detector around the tissue boundary. The light propagation on the phantom takes place in Near-Infra-Red wavelength. The incident light on the tissue boundary was absorbed and scattered. The scattered rays are detected by the photo-detector and scattered voltage of the tissue was measured. The scattered voltages vary for normal and tumor cell in the range of…

radiation therapy (IMRT). Intensity-modulated radiation therapy is a newer, modern technique that uses advanced technology to manipulate beams of radiation to conform to the shape of a tumor target. IMRT uses various small photon or proton beams of different intensities and angles to accurately irradiate a tumor. Unlike other types…

Comparative morphological analysis of paediatric double hit lymphoma to those seen in adults The index patient had an incisional rectal biopsy initially which displayed features in keeping with a diffuse large B-cell lymphoma. The neoplastic tumour cells displaying a diffuse arrangement. The individual cells having an increased nuclear-to-cytoplasmic ratio, round nuclei with vesicular chromatin pattern and prominent nucleoli. The tumour showed CD20, BCL6, and CD10 immunopositivity was…

Sensitivity of Cancerous C.elegans with Mitochondria Dysfunction Mitophagy is a selective autophagic elimination of damaged or excessive mitochondria, especially when cells are under adverse stress. Mitophagy has been identified as the cause of various human diseases and even cancer. In recent years, researchers gradually regard mitophagy as the target for cancer treatment, although the role of mitophagy in the developmental and metabolic process of cancer is still not clear. In this…

swelling on or inside the ovary. It may be solid or filled with fluid. If it is solid, it is called a tumor. This can be frightening because it immediately brings cancer to mind, but tumor is just the medical term for any swelling. There are many types of ovarian cysts, namely, functional cysts, dermoid cysts, serous & mucinous cystadenomas, endometriomas, functional tumors, fibromas and brenner tumors. Conversely, the choice of ovarian cyst treatment used to treat the cysts differ between the…

Peripheral giant cell granulomas (PGCG) are relatively uncommon reactive exophytic lesions of the oral cavity. Such a term is also synonymous to peripheral giant cell epulis, peripheral giant cell reparative granuloma though the word reparative granulomas is now considered obsolete in modern medicine because it’s not truly reparative.4,5 Clear aetiology of PGCG still remains elusive to and what is available currently are the laid hypothesis by various scholars for example local irritation from…
