Metastasis Metastasis is a pathogenic agent's spread from an initial or primary site to a different or secondary site within the host's body; it is typically spoken of as such spread by a cancerous tumor. The newly pathological sites, then, are metastases. Cancer occurs after cells are genetically altered to proliferate rapidly and indefinitely. This uncontrolled proliferation by mitosis produces a primary heterogeneic tumour. The cells which constitute the tumor eventually undergo metaplasia, followed by

Benign Prostatic Hyperplasia (BPH): Definition, Epidemiology and Etiology Benign prostatic hyperplasia is a common disease with proliferation of the periurethral zone (transitional zone) of the prostate, which leads to lower urinary tract symptoms (LUTS). Since BPH involves hyperplasia rather than hypertrophy, the often used term benign prostatic hypertrophy should not be used.he prevalence of benign prostate hyperplasia is age dependent: starting with the age of 35, the prevalence increases each decade by 15%. Nearly 100% of 90 year old men have benign prostate hyperplasia (pathologic definition). The pathologic prevalence does not correlate with the clinical significance.

Breast Apocrine Metaplasia Apocrine metaplasia is sometimes described as a ‘benign epithelial alteration’ of breast tissue, which means that epithelial cells are undergoing an unexpected change. The word apocrine means something to do with sweat, but only a resemblance. It’s not actually sweat gland related.pocrine metaplasia is a ‘ non-proliferative ‘ breast lesion, and is usually associated with breast fibrocystic disease. The term “proliferative” would mean that cells are growing and growing, and in a somewhat unpredictable way. Proliferative cells growth is therefore usually associated with carcinoma.

- Two types of metaplasia are common in chronic nonerosive gastritis: mucous gland and intestinal. Mucous gland metaplasia (pseudopyloric metaplasia) occurs in the setting of severe atrophy of the gastric glands, which are progressively replaced by mucous glands (antral mucosa), especially along the lesser curve.

Neoplasm Definition Neoplasm Definition. By Dr Ananya Mandal, MD. The term neoplasia refers to a mass that has developed due to abnormal cell or tissue growth. Neoplasia refers to various types of growths including non-cancerous or benign tumors, precancerous growths, carcinoma in situ and malignant or cancerous tumors. The term neoplasm is derived from a combination of the Greek words neo meaning new and plasma meaning formation.

Hyperplasia Hyperplasia, or hypergenesis, is an increase in the amount of organic tissue that results from cell proliferation. It may lead to the gross enlargement of an organ and the term is sometimes confused with benign neoplasia or benign tumor. Hyperplasia is a common preneoplastic response to stimulus. Microscopically, cells resemble normal cells but are increased in numbers. Sometimes cells may also be increased in size. Hyperplasia is different from hypertrophy in that the adaptive cell change in hy

Girl or boy name or both? Best Answer: I would argue that they're all male given names, though it absolutely depends on what country you are from. For example, in the United States, it is perfectly acceptable to name a little girl Avery or Kendall. Charlie could be a girl's name if it was short for Charlotte, and I've even met a female Logan. The rest I would argue are undoubedtly male names.

- Endometrial hyperplasia is an abnormal thickening or growth of the lining of the uterus. There are several varieties: Simple hyperplasia. Complex hyperplasia without atypia-this type is a little thicker than simple hyperplasia, and has more crowding and abnormal architecture to the glands.Without treatment, about 10% of patients will progress to endometrial cancer.omplex hyperplasia without atypia-this type is a little thicker than simple hyperplasia, and has more crowding and abnormal architecture to the glands.

What is Neoplasia? - Definition, Types & Examples - Definition, Types & Examples This lesson will discuss the concept of neoplasia. We'll specifically talk about the differences between benign tumors, carcinoma in situ, and malignant tumors. This lesson will also define metastasis and oncology and show examples of different types of malignant and benign tumors.

Dysplasia 1 Dysplasia is the earliest form of pre-cancerous lesion which pathologists can recognize in a pap smear or in a biopsy. 2  Dysplasia can be low grade or high grade (see  Carcinoma in situ  below). 3  The risk of low grade dysplasia transforming into high grade dysplasia, and eventually cancer, is low.

- Therefore, let's just focus on the important definitions you need to recall: Neoplasia is the abnormal growth and proliferation of abnormal cells or abnormal amounts of cells due to a benign or malignant process. There can be benign tumors, or neoplasms, and malignant ones. Remember that it's the malignant tumors, or cancer, that can metastasize, which is when cancer spreads around the body.

Causes of Hyperplasia Causes of Hyperplasia. Hyperplasia, and particularly atypical hyperplasia, is considered one of the risk factors for breast cancer—and while there are no known causes of hyperplasia, genetics (i.e., a family history) and weight and lifestyle (especially being overweight) have been linked to breast cancer.
