Malignant Neoplastic Diseases are tumors or malignant growths brought on by abnormal cells that have the ability to spread to anywhere in the body via the bloodstream. Malignant neoplastic disease are commonly known as cancer.
Neoplastic disease in a more technical sense is the excessive division of cells. This is caused by a variety of factors, that results in the atypical bodies of tissue neoplasms. A neoplasm has the ability form anywhere in the body and is commonly called a tumor. More often than not the term noeplasm tumor is used in conjunction with cancer, neoplasms can also be benign or nonmalignant. There are numerous causes, symptoms, diagnosis and treatments as well as different prognoses of people with neoplastic disease.
There are numerous factors than enhance the risks of developing neoplastic disease. Prolonged use of excessive consumption of alcohol, smoking and obesity have all be linked to the disease. Also, lowered immune systems and genetic predisposition can also be factors. neoplasms can also be caused by viruses such as hepatitis B and the human papilomavirus (HBV). Overexposure to sun, chemicals and other environmental toxins as well as radiation have been known to also play roles in the development and causes of neoplastic diseases.
Symptoms of neoplastic disease vary in severity and type. Commonly they are are related to the location of the neoplasm and are usually generalized. Some typical symptoms include night sweats, weight loss, anemia, fatigue and shortness of breath. However, there also may be more visible symptoms such as skin lesions or lumps. Occasionally, the symptoms can be asymptomatic meaning they do not appear until the disease is advanced.
The diagnosis of neoplastic diseases vary greatly. The most common and well known method is a biopsy. This is where the cells of the neoplasm are examined. This is an extremely reliable test as it confirms the malignancy as well as the type of growth. Other methods include magnetic resonance imaging (MRI), positron emission tomography (PET) and computerized axial tomography (CAT). These are usually done after the initial diagnosis to map the size, spread of the disease and exact locations. Other times blood tests are done which check for markers in the blood which can point to tumors. Bone marrow biopsies are common for diseases as as leukemia.
Treatment option for neoplastic disease vary vastly. Benign neoplasms usually require no treatment and are commonly removed without any further complications. Lesions appearing on the surface skin are also usually removed without complication. However, malignant forms of the disease will require other methods. These can include surgery, chemotherapy and radiation. Many times depending on the severity treatment is a combination of the three mentioned. If cancers have spread to organs such as lymph-nodes, these organs are usually removed to prevent further spreading.
Prognosis will vary based on location and malignancy. A benign neoplasm will have a better prognosis than maligannt but there are times where a malignant neoplasm is not treatable. The location and form will determine the treatment options as some respond better depending on these factors.
