Slide 1-

Breast Cancer Research Presented by Manish Modi Stevens Institute of Technology REU SUMMER 2005
Slide 2-

Statistics More than 180,000 new cases of invasive breast cancer are diagnosed and more than 40,000 deaths result from the disease each year.1 Each year, about 1,300 men in this country learn they have breast cancer 2
Slide 3-

What is Breast Cancer? Cancer that starts in the breast. The main types of breast cancer are ductal carcinoma in situ, invasive ductal carcinoma, lobular carcinoma in situ, invasive lobular carcinoma, medullary carcinoma, and Paget’s disease of the nipple. www.abcgonline.com/archive/2000/diction/diction.htm

2005 Estimated US Cancer Deaths* ONS=Other nervous system. Source: American Cancer Society, 2005. Men 295,280 Women 275,000 27% Lung and bronchus 15% Breast 10% Colon and rectum 6% Ovary 6% Pancreas 4% Leukemia 3% Non-Hodgkin lymphoma 3% Uterine corpus 2% Multiple myeloma 2% Brain/ONS 22% All other sites Lung and bronchus 31% Prostate 10% Colon and rectum 10% Pancreas 5% Leukemia 4% Esophagus 4% Liver and intrahepatic 3% bile duct Non-Hodgkin 3% Lymphoma Urinary bladder 3% Kidney 3% All other sites 24%

2005 Estimated US Cancer Cases* *Excludes basal and squamous cell skin cancers and in situ carcinomas except urinary bladder. Source: American Cancer Society, 2005. Men 710,040 Women 662,870 32% Breast 12% Lung and bronchus 11% Colon and rectum 6% Uterine corpus 4% Non-Hodgki lymphoma 4% Melanoma of skin 3% Ovary 3% Thyroid 2% Urinary bladder 2% Pancreas 21% All Other Sites Prostate 33% Lung and bronchus 13% Colon and rectum 10% Urinary bladder 7% Melanoma of skin 5% Non-Hodgkin 4% lymphoma Kidney 3% Leukemia 3% Oral Cavity 3% Pancreas 2% All Other Sites 17%

Types of Breast Cancer Breast Cancer In Situ () In Situ Breast Cancer is the preliminary kind in which the cancer has not spread to internal organs (good prognosis) Invassive () Invassive Breast Cancer a developed form of the disease that has already started to affect internal organs.
Slide 8-

Ductal Carcinoma Tumor develops in the tubes that connect the lobular (milk producing tissues) to the nipple. Two types of Ductal Carcinoma DCIS (Ductal Carcinoma in situ) IDC (Invasive Ductal Carcinoma) Invasive Ductal Carcinoma Accounts for 80% of all breast cancers Paget’s Disease

Slide 10-

Lobular Carcinoma Develops in the Fatty tissue in the Breast LCIS (Lobular Carcinoma In Situ) Periperal Tumor that can be removed ILC (Invasive Lobular Carcinoma) Cancer has metastisized other organs

Prevention Diet Drugs Early Detection
Slide 14-

Drugs Harmonal Therapy SERMs (Selective Estrogen-Receptor Modulators) Aromatase Inhibitors Biologic Response Modifiers
Slide 15-

SERMs Bind to estrogen receptors in breast cancer cells, starving cancer cells Tamoxifen (Nolvadex) Evista (raloxifene) Fareston (toremifene) Tamoxifen Most commonly used Hormonal Therapy Used to help men and women
Slide 16-

Aromatase Inhibitors Prevent production of estrogen in adrenal glands Common Aromatase Inhibitors Aromasin (exemestane) Femara (letrozole) Arimidex (anastrozole) Megace (megestrol)
Slide 17-

Biologic Response Modifiers Bind with certain proteins on breast cancer cells, preventing their growth Herceptin (trastuzumab) Other Hormonal Therapies Treat breast cancers that are dependent on estrogen for survival Zoladex (goserelin acetate) Faslodex (fulvestrant)
Slide 18-

Early Detection Breast Cancer Self Test Mammography Automated Target Recognition Technology Applying Wavelets to Mammograms
Slide 19-

Mammography Uses X-rays Primary Screening Method 1951 Leborgne first showed presence of calcification using a mammographic image Mammography Quality Standards Act improved quality and interpretation of images Low positive predictive rate

Slide 22-

Improving the Mammogram: Even well trained radiologists misdiagnose 10-20% of mammograms they review1 Applying Wavelets Improves texture of images Filters/Windows signals and performs Fourier Transforms Use of Compression Methods (Huffman) Computer Aided Diagnosis

Pro’s For Using this Technique Microwave Attenuation low enough to allow imaging of the entire breast Low Power Pulses (avoids ionization) Microwave Imaging in Space Time Allows 3D rendering Allows Discovery of tumors <0.5 cm Microwaves frequency in the middle High Frequency allows better resolution images Low Frequency allows better penetration
