cancer 2nd most common cause of death in the united states
Cancer2nd most common cause of death in the United States
  • Uncontrolled growth and spread of abnormal cells can result in death.
  • Over 9.8 million Americans alive today have a history of cancer. (3 million in 1971)
  • About 547,000/year people will die of cancer.
  • About 500,000 (4 of 10) people diagnosed with cancer will be alive in 5 years.

(www.cancer.org, 2006)

breast cancer specific
Breast Cancer Specific:
  • The American Cancer Society estimates in 2006 that …
    • there will be 212,920 new cases of invasive breast cancer to be diagnosed, and 61,980 non-invasive cases.
    • approximately 40,970 females are expected to die from breast cancer.
    • about 1,720 cases of breast cancer expected in men, accounting for <1% of all breast cancer. Approximately 460 men will die of this diagnosis.
  • The National Cancer Institute estimates about 2.3 million women with a history of breast cancer were alive in 2002.

(American Cancer Society, www.cancer.org, 2006)

Biopsy:

    • Fine-needle aspiration:
    • Cutting needle biopsy:
    • Incisional biopsy:
    • Excisional biopsy:

Suction from syringe to

gather clumps of cells from a tumor.

Obtain small core of tissue

Surgical removal of small area of tissue.

Surgically remove entire tumor for

analysis.

(Altman, 1992)

Anatomic site of primary tumor (Lung, colon, breast).

  • Classification of the tissue of origin (Epithelium, connective tissue)
  • Extent of tumor progression (Degree of invasion or metastasis)
  • Degree of cell anaplasia (Benign or malignant)

Tumor Nomenclature

tumor localized swelling or mass
Tumor - Localized swelling or mass
  • Benign:
    • Tumors can compress, invade and destroy adjacent normal tissue; do not invade other tissue and generallynot a danger to life.
  • Malignant:
    • Endanger life. Can choke out normal tissue, and spread to other parts of the body (Metastases) through the blood and lymph systems.

(Dollinger et al, 2002)

cell disorders
Hyperplasia

Dysplasia

Metaplasia

Anaplasia

An increase in the number of cells of a tissue or organ without tumor formation.

A cell variation in size and shape from normal. More severe than hyperplasia.

Unusual cell growth. Differentiated tissue from one kind into another.

Most serious growth. Absence of normal cellular differentiation in tissue. Cells divide at an increased rate compared to normal cells. Found in most malignancies.

Cell Disorders

(Otto, 2004)

carcinoma
Carcinoma
  • Develops in the lining and covering tissues of organs
  • 85 – 90% of all Cancers are generally found in organs that secrete
    • Examples: Lungs secrete mucus, breast secretes milk, pancreas secretes digestive juices

Carcinoma in situ: Earliest stage of cancer, with the tumor confined to a local area.

Sarcomasaccount for 2% of breast cancer. This is a solid tumor that originates in connective tissue, bone, muscle, cartilage or fat.

:

(Love, 1990)

where breast cancer can develop
Where breast cancer can develop:
  • Milk ducts
  • Between ducts
  • In fat
  • In lymphatic system
  • Blood vessels
  • Nipple
  • Lobes where milk is produced

(Lang, 2005)

slide19
Ductal

Inflammatory: Blockage of the lymph drainage from skin on the breast. Red, swollen, thick and pitted.

Medullary: Invasive, well defined division of cancer and non-cancer tissue. Large Ca cells and immune system cells around the tumor border.

Mucinous: Invasive cancer cells produce mucus and grows into a jelly-like tumor.

Lobular

Paget’s disease: Affects nipple and areola. Starts in milk duct as either in situ or invasive cancer. Good prognosis.

80% of breast cancers are invasive ductal carcinoma. Pathologic classifications of less common types of breast cancer:

(Jennings-Dozier et al, 2002)

7 warning signs of cancer
7 Warning Signs of Cancer
  • C change in bowel or bladder habits
  • A a sore that does not heal
  • U unusual bleeding or discharge
  • T thickening or lump in breast or elsewhere
  • I indigestion or difficulty swallowing
  • O obvious change in a wart or mole
  • N nagging cough or hoarseness

(Dollinger, 2002)

additional warning signs specific to breast cancer

Additional Warning Signs Specific to Breast Cancer

Breast discharge or bleeding

Change in shape of breast or nipple

Tender lymph nodes

Skin dimpling

Noted rash or veins of the breast

(Dollinger, 2002)

risk factors for breast cancer
Risk Factors for Breast Cancer
  • Family history (less than 7% of breast cancers are thought to be hereditary).
  • Long menstrual cycles or early menarche
  • Late menopause
  • First pregnancy after age 30.
  • Higher education or socioeconomic class
  • Stress
  • Obesity
  • Living in Northern U.S.
  • History of colon or other female cancers.

(Dollinger, 2002)

differential diagnosis before you treat make sure the diagnosis is correct
Differential Diagnosis: Before you treat, make sure the diagnosis is correct.
  • Differential diagnosis is the method by which a clinician considers the possible causes of a patient’s clinical findings before making a final diagnosis.
  • Patient with diagnosis of breast cancer:
    • Breast, lung and prostate carcinomas.
    • Be aware of any history of malignancy.
    • “Lymphedema is an important differential diagnosis in limb swelling”

(Tiwari, 2003)

Methods to Diagnose Breast Cancer

(Altman, 1992)

diagnostic tools explained
Diagnostic tools explained
  • Biopsies:
  • Fine Needle Aspiration – Removes cells through a thin hypodermic needle connected to syringe and moved in and out of tumor to acquire tissue for evaluation. Fluid is evaluated by a cytologist. This method used for a palpated lump, if negative further biopsies needed.
  • Core Needle Biopsy – A large needle which can yield a tissue sample. Needle insertion can be guided by ultrasound or a MRI scanner, which is called image-guided. This tissue study is completed by a pathologist.
  • Open biopsies are often prescribed to double check or rule out cancer.
  • Incisional biopsies remove tissue samples through a small incision, enough tissue for pathologist to confirm his conclusion.
  • Excisional biopsies remove the entire lump and some healthy tissue surrounding the lump.

(Braddock, 2002)

diagnosis continues
Diagnosis continues
  • Mammogram is a technique completed routinely for early detection, This is completed by compressing the breast and obtaining an oblique and a craniocaudal view. Good procedure to spot lumps to small to be felt. Patterns of interspersed cords of cancer cells among the breast tissue make diagnosis and detection difficult.
  • Magnetic resonance imaging (MRI) Combination of magnetic and radio waves that are a high sensitivity device which can show the extent of the invasive or non-invasive disease. This procedure is completed by showing blood vessels in tissue. This tool is valuable for high risk females as well as following neoadjuvant therapy.
  • CAT scan is computer aided to create a three dimensional images of organs and structures for further specific diagnosis, if needed.
  • Ultrasound is a high frequency sound wave beamed through breast tissue and reflections are detected and turned into images. Cancer cells usually have a distinct outline compared to normal cells. The results of this examination are operator dependent.
  • Bone scan detects increased blood circulation in a bone, which could reveal metastases.
  • Pet Scan (Positron emission tomography) similar to X-ray except Pet scans show cell activity, by detecting the rate cells consume glucose. Cancer cells use up sugar faster than normal cells.
  • Tumor testing can be completed by using estrogen and progesterone receptors as well as other genetic measurements.

(Dixon, 2006)

BREAST - Monthly breast self-exam between Age 20-40 Health professional breast check /3yrs

  • Age 40 - 1st mammogram
  • Age 40-50 - Health professional breast check/yr; mammogram every 1-2 yrs.
  • Over 50 = Health professional and annual mammogram

Female Protection Against Cancer

(Jennings-Dozier et al, 2002)

male breast cancer
Male breast cancer
  • < 1% of breast cancer
  • 1500 new cases and 400 fatalities/year (Compared to 203,500 new cases in women)
  • Risk increases with family history of mutated BRAC2
  • Prognosis similar to female, testing size, grade and nodes.
  • Treatment with mastectomy and other interventions as prescribed by oncologist.
