There are 2 types of asbestos fibres based on crystalline structure;a-serpentine{chrysolite}and b-amphibole. Included within the amphibole are amosite,tremolte,crocidolite and anthophyllite.

Glioblastoma Multiforme Glioblastoma Multiforme, or GBM, is the most aggressive and most common primary brain tumor, but it isn’t quite that simple. GBM has quite a complex background and can start in many different ways, so that’s why I feel I should start from the very beginning of GBM so that you can fully understand what it is all about. Let me start by saying that GBM is the highest grade of glioma brain tumors, so it only makes sense for me to tell where GBM and glioma tumors come from. A glioma is a type of brain tumor that grows from glial cells, cells that support nerve cells with energy and nutrients and help maintain the blood-brain barrier. There are various types of glial cells, each with a different function.…
Benign tumors are totally different than malignant tumors. In other words, benign tumor is noninvasive and encapsulated, it is well-differentiated in, which it composed of organized and specialized cells that closely resemble the normal cells.…
The brain is one if not the most important organ in our body. It controls the vital functions of the body including speech, thoughts, memory, vision, breathing, movement and more. Since the brain is such an important organ, any little change or imbalance in the brain can lead to a serious problems. Any amount of swelling, bacteria, or abnormal growth in the brain could lead to a life threatening illness. An abnormal growth, such as a tumor impedes on different functions depending on where that tumor lies within the brain.…
A pituitary tumor is an abnormal growth in the pituitary gland. The pituitary gland is the part of the body that regulates most hormones. Some of these pituitary tumors produce excessive hormones, which regulate important body functions, while others restrict some of the normal functions of your pituitary gland, thus decreasing hormone production. Around 20% of the human race have pituitary tumors.…
2.3 Function of Tumour Marker Tumour marker are was the product of cancer. Thus, tumour marker can help to use as assessment for cancer case. Generally, the outcome of tumour marker test is unreliable as the non-cancerous condition may affect the positive results. Prostate Specific Antigen can be used to evaluate prostate cancer.…
Neuroblastoma is a type of childhood cancer that starts in immature nerve cells in the sympathetic nervous system. The autonomic system ( which is part of the peripheral nervous system) is divided into to the parasympathetic system and the sympathetic nervous system. The parasympathetic nervous system controls activities when the body is at rest. The sympathetic nervous system controls involuntary body functions like breathing and digestion.…
Benign Lesions of the Breast: A) Benign proliferative breast disease: 1. Fibroadenoma: Fibroadenoma is the most benign soft tissue mass of the breast and accounts for approximately 40%-50% of all breast biopsies (Liberman, 2000). Usually it is occurring in patients between the ages of 20-35 years , it increases in size during pregnancy and tends to regress as the age of the patient increases, it is usually single, but in 20% of cases there are multiple lesions in the same breast or bilaterally. Grossly, the usual fibroadenoma is a sharply demarcated, firm mass, usually no more than 3cm in diameter (Rosai, 2004).…
For each type of a brain tumor the symptoms corresponding can vary based on the tumors type and location. However, the most common types of symptoms include; recurrent headaches, issues with vision, seizures, changes in personality, short-term memory loss, and difficulty speaking or comprehending. Recurrent headaches are you usually associated with metastatic brain tumors. Now these are not normal headaches that a typical person has in the morning but as the day progresses the headache seems to vanish. Nonetheless, a brain tumor headache is no ordinary everyday headache but one that can hurt and feel like the “worst headache of your life”.…
Once colon cancer has been spotted in the body a number of tests are run to make sure that the cancer is either benign or malignant. Colon cancer is the third leading cause of death from cancer patients. The process in which determining if the cancer is benign or if it is indeed malignant is called "staging. If the cancer is benign the tumor is just simply removed ,but if it is malignant more treatment is required.…
Can a mammogram save your life? Hard to believe this remains a topic of debate. Mammograms are x-ray images of a woman’s breasts used to detect cancer (“Mammograms”). While recognizing the potential effects of radiation and the issues around false positive/negative results, the benefits of mammograms far outweigh these concerns. These tests identify cancer early, increase chance of survival, and are a reliable method of preventative cancer screening.…
The figure at the right shows the difference in the process of the cell division between a normal cell to a cancer cell. The normal cell replication is even, while the cancer cell replication is nonstop. Neoplasm, an abnormal growth of a tissue, forms a mass referred to as a tumor. There are two types of tumors, malignant and benign. Malignant tumors are cancerous; they cause major health concerns as metastasis starts to take place.…
