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 the ECM and basement membrane

a higher survival rate due to a higher status of overall health. (Furuya) Ovarian cancer manifests itself in the form of epithelial tumors that develop on the exterior of the ovaries. Their growth is hasty and cancer cells migrate quickly by direct extension into organs within close proximity and through circulating blood and lymph. The development of these tumors can be related to a response initiated through excessive estrogen exposure. (Ignatavicius) Symptoms generally include abdominal pain

pressure (hypertension). CAUSES The most common cause of acromegaly is an overproduction of growth hormone by the pituitary gland. This can result from: A noncancerous (benign) tumor on the pituitary gland (common). A tumor in another part of the body (rare). Acromegaly can also be caused by a tumor that makes growth hormone itself. SIGNS AND SYMPTOMS Common signs and symptoms include: Larger than normal hands‚

Thus‚ as an alternative to treatments designed only to kill cancer cells‚ researchers must today focus on developing the means to reduce or even to prevent the migration of these cells14. * Tumor-cell invasion and migration. The process of tumour-cell invasion and metastasis is conventionally understood as the migration of individual cells that detach from the primary tumour‚ enter lymphatic vessels or the bloodstream and seed in distant

exploitation of tumor mutations and their ability to establish an immune response in the body. Given that about 95% of a tumor mutation is specific to the one patient concerned‚ the idea of exploring those mutations on an individual level has become more popular. The basis of the personalized cancer vaccine concept is that each cancer patient has tumor cells that produce specific neoepitopes‚ which are the mutated proteins specific to that tumor in that one patient. Therefore‚ if each tumor cells in a

In Egypt‚ astrocytic tumors are the most common glial tumors (79.4% of all gliomas)[1].Histopathologic diagnosis is important for definitive prognostication and treatment. According to the 2007 WHO classification‚ astrocytoma is classified into four pathological grades: pilocytic astrocytoma (Grade I)‚ diffuse astrocytoma (Grade II)‚ anaplastic astrocytoma “AA” (Grade III) and glioblastoma multiforme “GBM” (Grade IV) [2]. The tumor cells vigorously invade the

Angiogenesis is the growth of new blood vessels that tumors need to grow. The field of angiogenesis has grown enormously in the past 30 years‚ with only 40 papers published in 1980 and nearly 6000 in 2010. Why do you think angiogenesis research grew so fast? Studies show that angiogenic therapies provide a potential to conquer cancer‚ heart diseases‚ and more than 70 of life’s most threatening medical conditions. We all know that tumor can really be a serious thing for an embryo. According
