Metastasis in know as the spreading of cancer cells from one location in which the tumor is present to another part in the body. Metastasis is one major in distinguishing the difference between a benign or malignant tumor. Along with this metastasis is also a huge cause of why death occurs in cancer. In the absence of metastasis in a benign tumor‚ the cancer can be removed with chemotherapy or through surgery. Once cancer has metastasized it is not easy to remove it from the affected area.

of pulmonary metastasis with widespread progression that leads to respiratory failure. Tumor invasion and metastasis is multistep complex process in which tumor cells alter cell–extracellular matrix (ECM) interactions at the primary tumor site to invade adjacent tissues and thus translocate through the vasculature to other systems to form secondary tumors there. A family of proteolytic enzymes called MMPs are the key proteases playing an important role in tumor invasion and metastasis by degrading

Once the SLN is localized‚ a suture is placed through the node to provide traction. The node is then dissected free from the surrounding tissue. All feeding blood vessels‚ afferent and efferent lymphatics may be ligated. Using the radiocolloid method‚ the gamma probe is used to locate any other SLNs and to confirm low radioactivity counts in the axilla and no residual SLNs. Ex vivo and in vivo radioactivity counts are recorded for each node. The axillary tissue is also carefully palpated for any

changes occurring during the natural history of tumor growth and development. Genetic changes accumulate in the form of mutations‚ activation of proto-oncogenes‚ or the loss of tumor suppressor genes that could promote tumor progression‚ invasion‚ and metastasis; this process provides a rational basis for targeting one or more critical genetic defects in cancer cells by using gene-mediated therapy approaches(Parks & Bramson‚ 1999). Glioblastoma is a heterogeneous disease with a spectrum of histopathological

very low at 30%. In advanced prostate cancer‚ metastasis occurs in distant organs such as the brain‚ liver‚ lungs‚ lymph nodes‚ and bone. Particularly‚ 90% of patients with advanced prostate cancer present metastasis in the bone. Both localized and advanced prostate cancers do not respond to standard chemotherapeutic interventions and thus require alternative treatments. (is treatment of bone mets only palliative? If so‚ it can be said here) Metastasis of prostate cancer cells initially depends on

spread‚ it is called metastasis (3). Cancerous cells split from where they initially formed (primary cancer)‚ hitchhike through the framework of the blood or lymph system‚ and form new tumors (metastatic tumors) in different areas of the body. The metastatic cancer is not any different than the original cancer and tumor (4). For example‚ abnormal cells in the lung can travel to the bones and develop there‚ but it’s still classified as lung cancer. The reason cancer and metastasis is so dangerous is

Theory on the Role of Cancer Stem Cells in the Organ Tropism of Breast Cancer Metastasis Organ Tropism This paper is on the role of cancer stem cells in the organ tropism of breast cancer metastasis. Cancer mortality is increasing despite vast research efforts. This paper will discuss the characteristics of cancer stem cells and their potential microenvironments. I will focus on a theory of treatment for breast cancer and the role of cancer stem cells in organ tropism. Adult stem

a growth or tumor that can appear painless. Testicular cancer is a pain that involves the testes and it may cause a swelling or a lump that man or boys can feel or touch by themselves or they can go for a checkup with a doctor. The cancer can be metastasis into either parts of the body by a flow of the blood stream or by lymphatic system. The testicular cancer has a rate of 95 percent and that’s a very good rate for that type of cancer for men. Testicular cancer can harm young men at the age of 18

These are usually slow growing‚ with late metastasis predominately to the liver‚ adrenal glands‚ kidneys and bones. Tumors usually range in size from 1 to 10 cm. They are typically found in the central bronchi‚ although one third occur beyond the segmental bronchi. The most characteristic radiographic
