Stage 0
Cancer cells are present in either the lining of the glands that make milk (lobules) or the tubes (ducts) that link these glands to the nipple. But cancer cells have not spread to the nearby fatty tissue.
Stage I
Cancer has spread from the lobules or ducts to nearby tissue in the breast. Cancer cells have not spread to surrounding lymph nodes, stays in the lining.
Stage II
Cancer has spread from the lobules or ducts to nearby tissue in the breast. Sometimes cancer cells have also spread to the lymph nodes.
Stage III
Later stage of breast cancer (locally advanced). Tumors have spread to lymph nodes under the arm, chest or above or below the collarbone. Tumors that have spread to other tissues near the breast may also be considered stage III.
Stage IV
Advanced stage of breast cancer (Metastatic). Cancer has spread from the breast and lymph nodes to other parts of the body such as the bone, liver, lungs, or brain.
Ductal carcinoma
Breast cancer that occurs in the milk ducts.
Lobular carcinoma

Detection of "hot" and "cold" spots in tissue. Associated w/circulation.
Tissue biopsy
Tissue sample for microscopic examination.
Why is breast biopsy done?
To determine the exact nature of a mass in the breast. It involves the removal of breast tissue for pathologic examination.
Fine Needle Aspiration (FNA)
22 or 25 gauge needle and syringe are inserted into the mass and a few cells are aspirated and sent to pathology to cytologic studies.
Core biopsy
A large bore trocar (True-cut needle) is inserted into the mass and a core of suspended tissue is w/d for histologic examination.
A computer-guided system used to digitally loacte and pinpoint nonpalpable breast leisons.
Sentinel Node
The breast mass in injected w/a radioisotope dye several hours before the procedure. The dye is taken up by the lymph nodes of the breast. The nodes are excised before the mass and a Geiger counter is used to locate the areas of radioactivity.
Fiberoptic ductoscopy

The thyroid gland is controlled by the__________loacted within the brain which makes_____________.
Pituitary gland, TSH
Tests for diagnosing Thyroid disease
Blood tests (T4 and T3), Ultrasound exam (during pregnancy, tells is a thyroid humor is solid or cystic), Thyroid scan (tells if the tumor os functioning or nonfunctioning, Radioactive Iodine uptake (hyperthyroid), and TSH assay (increase for hypo and decrease intake for hyper).
Euthyroid (well) goiter
If dietary iodine is slightly inadequate, too little thyroxin will be secreated, and the pituitary will sense the deficiency and produce more TSH. The thyroid gland will enlarge to make sufficient thyroxin.
Hypothyroid goiter
If dietary iodine is severely reduced, the gland will keep growing under the influence of TSH, but it may never be able to make enough thyroxin.
Symptoms of Hyperthyroidism
Fatigue, wt loss, nervousness, rapid heart beat, increased sweating, feeling hot when others don't, changes in menstrual periods, more frequent bowel movements, and tremors.
Increased fatty deposits behind the eyes causing the eyes to push foward. Usually seen in Graves Disease in someome w/Hyperthyroidism.
Removal of one or both lobes of the thyroid gland. Usually done due to hyperthyroidism or thyroid carcinoma. The parathyroid glands, imbedded posterially in the thyroid, MUST be spared for they produce CA.
Performed usually due to hyperparathyroidism. One to all four parathyroid glands may be taken. If all four are taken out, constant calcitonin level monitoring is needed. If one can be spared, usually they'll get implanted in the pt's forearm.
Partial Thyroid Lobectomy
Half of the thyroid lobe is removed. This operation is not performed very often, a benign leison must be ideally located in the upper or lower portion of one lobe for this operation to be a choice.
Thyroid Lobectomy
This is typically the "smallest" operation performed on the Thyroid gland. It is performed for solitary dominant nodules which are worrisome for cancer or those which are indeterminate following a fine needle biopsy.
Subtotal Thyroidectomy
Removes all the problem side of the gland as well as the isthmus and the majority of the opposite lobe. This operation is typical for small, non-aggressive thyroid cancers. Also a common procedure for goiters.
Total Thyroidectomy
This operation removes all of the thyroid gland. It is the operation of choice for ALL thyroid cancers-many surgeons prefer this for all thyroid cancers regardless of the type.
Complications of Thyroidectomies
Be careful of the recurrent laryngeal nerve! Pneumonia, and Thrombophlebitis
Liver biopsy is used to determine...
Liver disease or transplant rejection, used when other non invasive exams ( abnormal liver function tests, staging for chronic hepatitis, ID alcoholic liver dz, FUO, evaluation of cirrhosis~hardening of liver tissue, and screening for familial dz) can not make a diagnosis.

A new opening in the stomach and jejunum also known as a Roux-en-Y. This procedure may be done to reestablish continuity between the stomach and intestinal tract~ tumor obstruction or gastric bypass in bariatric sx.
The jejunum is divided, the distal end is anastomosed to the side of the stomach, and the proximal end is anastomosed to the side of the jejunum at the lower level. The result is a Y-shaped anastomosis that diverts the flow of bile and pancreatic enzymes directly into the jejunum bypassing the created gastric stoma.
Bariatric surgery
Used to treat morbid obesity, the capacity of the stomach is reduced to approximately 30ml (size of a medicine cup) to restrict food absorption or intake.
Gastric bypass
The size of the stomach is reduced by creating a small pouch in the fundus.
Vertical Banded Gastroplasty
4 linear staple lines are placed vertically on the lesser curvature side of the stomach just left of the gastroesophageal junction. This allows for a small passage of gastric contents and the total intake at any given time is about 1 ounce. This surgery has better outcomes compared to gastric bypass.

Compression forces and Deceleration forces.
Compression forces
Also known as concussive forces may result from direct blows or external compression against a fixed object. Most commonly, these crushing forces cause tears and subscapular hematomas to the solid viscera. These forces also may deform hollow organs and transiently increase intraluminal pressure, resulting in rupture.
Deceleration forces
