Tumor

Glomus tumors are usually the benign tumor of glomus cells with immunocytochemical and structural features of smooth muscle cells [1]. The majority of cases of glomus tumor are benign but rarely they demonstrate malignant features both clinically and histologically (aka glomangiosarcoma) [2]. Glomangiosarcoma in extracutaneous sites is uncommon but few cases have been reported. Glomangiosarcoma of the heart is extremely rare due to rarity or near absence of glomus bodies in the myocardium. We…

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…

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…

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…

In 1896 Roentgen presented the idea of the x-ray. Only a few months later, systems were already being designed to use the x-ray for diagnosis. Within 3 years, the radiation was being used in cancer treatment. A single idea for treatment grew in a short period of time, with the help of technology. Today we are seeing scientific advances like never before. As advancements in technology grow, the options for cancer treatment improve drastically. Sterotactic radiation, cytotron, and an…

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…

aspartames have also shown to cause headaches and migraines. Headaches can also be experienced in lower doses if one has an allergy to formaldehyde, a byproduct of aspartame. Aspartame consumption in rats has shown to promote the growth of malignant tumors, which should raise doubts on whether aspartame in truly safe for human consumption. Animals are good to use for aspartame studies because humans studies are affects by too many uncontrollable variables that could tamper with the results, such…

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…

Hypoxia is a crucial feature of locally advanced solid tumors resulting from a poor oxygen supply delivery owing to excessive cellular proliferation and abnormal vascular architecture. Under these circumstances, cancer cells develop a series of responses in order to adapt to hypoxic conditions. The tumor suppressor p53 has been shown to mediate the cellular response to hypoxia depending on many contexts including cell type, duration and severity of hypoxic exposure. The sphingolipid ceramide,…

Targeting solid tumors - primary & metastatic - irrespective of their anatomical location in the body or pathological sub-type – and permeating drug molecules into the targeted tumor mass, will improve therapeutic outcomes and reduce life-threatening systemic toxicities induced by routinely administered chemotherapeutic regimens. Creating molecular dimension-specific temporary pores in the cell membrane using precisely computed, safe radiofrequencies (RF) from an external source, to…
