The term Neoplasm is a Greek word which means Noes-New, plasma-tissue
Types of Neoplasm
A benign tumor
- Slow growing
- Margin well defined
- Do not spread to other organs than that direct extension
- Benign tumors which arise from both epithelial and connective tissue are usually referred to with a name and a phrase called " Lomas"
- Grow more rapidly
- Margins are I'll define
- Infiltrate to surrounding tissue
- Malignant tumor of epithelial origin is called " carcinoma" while that of connective tissue or mesodermal origin are called " sarcoma"
Malignant Tumor may form metastasis
Metastasis - This means invasiveness to distant organs. This can be by:
- Direct spread
- Via lymphatic
- Via bloodstream
- Through body cavities
Causes of neoplasm
These are sometimes referred to as carcinogenic agents
- Nutritional Deficiency
- Trauma or dental irritation
- Virus e.g epsten bar (E.B) virus
- Premalignant lesion e.g. leucoplakia
- Vitamin deficiency
- Oral sepsis.
Effects of Neoplasm on human
This depends on the site of a tumor
- Pathological fracture
- Cachexia (a) Anorexia (b) malabsorption
Treatment of Neoplasm
- A combination. For example; both chemotherapy and surgery
There are many types of breast Neoplasms, which can be divided into the following broad oversimplified categories as a starting point.
- intralobular (epithelial and stromal)
- breast lymphoma
- metastasis to breast
Intralobular and interlobular refer to the terminal duct lobular unit.
Although many of the epithelial lesions/changes listed below are neoplastic, they are best thought of as neoplasms at increased risk and along a continuum with normal breast at one end and invasive carcinoma at the other.
