An abnormal new growth
enclosed sack like pouches that have a definite wall; usually containing a liquid, solid or semi-solid material
neoplasms are also called
a type of cyst present on the ovary. Most are caused by excess scar tissue from the deterioration of a graafian follicle
Ovarian cyst (dermoid)
a rare ovarian cyst that contains a waxy tissue and other structures not normally found in the body - like teeth or hair follicles
an abnormal sack like structure located on a sebaceous or oil gland.
Sebaccous cyst (wen)
another name for Sebaccous cyst
the manner or method in which the growth occurs
three types of non-neoplastic changes
a non-neoplastic change; excess growth; an increase in size of a body part or organ by an increase in size of the cells already present.
three types of hypertrophy
a type of hypertrophy; an increase in size of a body part or organ due to increased functional demand. Examples: The increase in size of the female uterus in preparation of pregnancy, breast tissue due to lactation.
a type of hypertrophy;an increase in size of a body part or organ due to disease - tumors. Example: Wilm’s tumor, a rare tumor of the kidney in children.
a type of hypertrophy;an increase in size of a body part or organ to compensate or make up for the loss of a similar or paired organ. Example: removal of a kidney, the other kidney would compensate; also the lungs, the lungs have the ability to work after the other has been removed
a non-neoplastic change; excess growth; an increase in size of a body part or organ by an increase in the total number of cells making it up.
a non-neoplastic change; the replacement of one type of tissue with another type of tissue not normally found in that part of the body. Example: oat cell carcinoma
Classification of neoplasms or tumors
the state of a disease
benign or malignant
GENERALLY a suffix of oma. Generally this type of tumor will not kill.
malignant tumor of connective tissue (bone cancer) occurs in persons under 30
malignant tumor of tissue of epithelial tissue (breast cancer or lung cancer) occurring in persons between 45- 60.
when a tumor is classified by tissue of origin; what tissue it originated first. Shown by its prefix
ALL of this type of tumor, if left untreated will kill
benign tumor characteristics(5)
1. Grow by expansion.
2. Don’t metastasize - don’t spread.
3. Don’t recur after surgery - removal or treatment.
4. Don’t cause great tissue damage.
5. Resemble original tissue of origin.
malignant tumor characteristics(5)
1. Grow by the process called infiltration. They take over existing tissue.
2. Mestatasize (spread) - the process by which a malignancy spreads itself to other parts of the body. Usually by means of the lymph or blood stream.
3. Can reoccur after surgery.
4. Cause extensive tissue damage.
5. No resemblance to original tissue of origin.
lining tissue. Also the inner most tissue.
BENIGN NEOPLASMS of Epithelial tissue (3)
2) Papilloma (polyp) .
3) Nevus (mole)
glandular - a benign tumor of glandular epithelial.
a benign tumor of epithelial that appears as a pedestal stalk like growth. Most frequently in the nasal cavity or intestinal track
