3. Thesis
Early detection is key in providing an optimistic prognosis for women diagnosed with breast cancer

4. Breast Anatomy
The breast tissue begins under the clavicle to below breast, axilla to sternum and includes the pectoral muscle

5. Breast Tissue Anatomy
The breast tissue is made up of fatty tissue, lobules, lobes and ducts
Lobules: Gland that produces milk in women who are lactating
Lobes: Made up of numerous lobules
Both the lobules and the lobes connect directly to the ducts
Ducts: Tubes that carry milk to the nipple during lactation

6. Types of Breast Tissue
There are four types of breast tissue: fatty, fibro glandular, heterogeneously dense, extremely dense Dense breast tissue is the most difficult to evaluate and make an accurate diagnosis

7. What Is Breast Cancer?
Type of cancer that occurs when the cells in the breast begin to grow in an abundance and form a tumor These cells can be found in the ducts, lobes or the glands Breast cancer is the number one cause of cancer in women: 1 in 8 women develop breast cancer

8. Breast Cancer Types
There are many types of breast cancer; however can be categorized into two main types: Noninvasive (in situ) and Invasive
Noninvasive: Often referred to as In Situ (in its original place). The cells do not break away and spread to any other healthy tissue
Ductal Carcinoma In Situ (DCIS): Abnormal cells are found in the lining of breast milk ducts. These abnormal cells have not spread or invaded beyond the walls of the ducts into surrounding breast tissue
Lobular Carcinoma In Situ (LCIS): Confined to the milk-producing glands (lobules) of the breast. Tumors classified as LCIS are made up of small cells that do not leave the lobules.
Invasive: Any cancerous cell that invades normal (healthy) tissue is deemed invasive.
Invasive Ductal Carcinoma (IDC): Originate in the milk ducts of the breast and travel to surrounding tissue.
Invasive Lobular Carcinoma (ILC): Begin in the lobules of the breast. The cells in the lobules disperse and invade surrounding tissue.

9. Risk Factors Gender: 1 in 8 women will develop breast cancer
Age: Risk increases after 45 years old
Ethnicity: Non-Hispanic whites have the highest risk
Family history: Maternal and Paternal
Genetics: Inheriting the gene mutation (BRCA1/BRCA2)
Previous Radiation: Specific to breast area
Other risk factors include: Smoking, being overweight, consuming more than 2-3 alcoholic beverages per day, not bearing children, and not breast feeding

10. Signs Of Breast Cancer

11. Diagnosing Breast Cancer
Self and clinical breast exam
A self breast exam is the first step. Consists of using the fingertips to press against the entire breast tissue to feel for any lumps or suspicious changes in the breast. These should be completed monthly.
A clinical breast exam should be completed from the patients primary care provider during the annual physical.
Imaging modalities:
Mammography
Tomosnythesis
Magnetic Resonance Imaging (MRI)
Ultrasound
Breast Biopsies

12. Mammography Gold standard of imaging for breast cancer
During a mammogram, the patient’s breast is placed between two flexible, radiolucent paddles that compress and flatten the breast tissue. This compression allows for the layers of the breast tissue to be spread apart, allowing for less overlapping of the tissue in the breast.
Limitations to mammography:
Low detection rate for those women with dense breast
High false positive recall rate (results that show a person has a disease when they do not)

13. Mammography-Images

14. Tomosynthesis
New screening tool that features pseudo 3D digital imaging; uses a low-dose x-ray system
Obtains multiple thin, high-resolution 2D slices and reconstructs them into 3D images
Provides better imaging for those women who have dense breast tissue; requires more angles. This results in an increase in accuracy of size, shape, localization of any tumors that may be detected
Uses increased compression allowing:
Less blurring on the image from patient motion
Tissue to be spread out further, which causes the tissue to become thinner
Thinner tissue will provide smaller abnormalities to be better detected on the images
Thinner tissue also means less dose to the patient
With smaller abnormalities being detected it provides earlier diagnosis of breast cancer, which can lead to more treatment options and a more positive prognosis

15. Mammography vs. Tomosynthesis
Breast Cancer in 2D (mammography) vs. 3D (Tomosynthesis)

16. MRI
MRI is a nonionizing imaging tool that uses strong magnets and radio waves that interact with the body to produce detailed images of organs and soft tissues in the body  
Used to aide in detecting the presence, stage and/or type of breast cancer
If cancer is detected, MRI will assist in measuring the size and shape of the detected lesion

17. Ultrasound
Ultrasound uses sound waves to help differentiate between a solid mass and a fluid-filled cysts in the breast
A fluid filled cyst detects different sound wave patterns that a solid structure
Ultrasound will not specify whether the tumor is cancerous or benign
Used for patients who have suspicious findings on a mammography or MRI.

18. Breast Biopsies
Performed when other imaging detects suspicious findings
Aide in diagnosing abnormalities in the breast tissue
Samples are obtained and sent to lab for testing
Lab reports assist in determining a patient’s treatment plan
MRI, ultrasound and x-radiation imaging guide the retrieval of fluid or small specimen
Ultrasound guided biopsy

19. Treatment Options
Once diagnosed, a patient may endure one or more of the following:
Surgical
Radiation therapy
Chemotherapy

20. Surgery Lumpectomy Mastectomy
Surgical removal of a lump that presents as cancerous inside the breast tissue
Less invasive than mastectomy
Surgical removal of the entire breast and lymph nodes to eliminate any and all tissue that may contain breast cancer
May have a single (one breast) or a double (both breast) mastectomy
Both techniques are methods to reduce the chance of cancer spreading or returning to the same area

21. Radiation Therapy
Uses ionizing radiation to direct all radiation dose solely to the cancerous cells and destroy them
Patients may receive radiation 5 days in a row, lasting up to 6-8 weeks
Radiation therapy machine
This form of treatment can be completed before or after surgery
Before surgery: Minimizes the tumor before removal (less tissue has to be removed)
After surgery: Targets the area removed in order to ensure all cancerous tissue was fully removed

22. Chemotherapy
Type of treatment that uses chemical substances that are administered intravenously over a course of time in cycles to kill the cancerous cells throughout the entire body
Usually done for patients with metastatic breast cancer
Administered either before or after surgery:
Before Surgery: Reduces the size of the tumor which results in less tissue being removed during surgery
After Surgery: Eliminates any cancerous cells that may still be present and/or to reduce the chances of the cancer returning
Most intensive treatment option
Because it is treating the whole body
Chemicals used causes lots of side effects such as: nausea, vomiting, appetite changes, severe constipation, and hair loss

23. Early Detection is Key
In order to avoid intensive treatment, such as chemotherapy, the focus of early detection is vital
Qualities of early detection:
Women being aware of their risk factors, so they know when to start their initial mammogram. This aides in detection of smaller lesions
Being aware of their signs and to take actions early
Obtaining a mammogram with tomosynthesis software increases early detection
When a patient is diagnosed early, they are provided with more treatment options

24. Follow-up Care
Monthly visits with the patient’s primary care provider to evaluate the patients body physically and mentally
Mammograms: follow up screening every six months or annually, dependent on how long a patient has gone without breast cancer

25. Prognosis
Due to earlier detection, 90% of women who have been diagnosed with breast cancer, survive for at least five years after initial diagnosis
Currently, there are 3.1 million (women) breast cancer survivors in the United States
It is estimated that 40,920 women succumbed to the disease in 2017

26. Conclusion Breast cancer is the number one cause of cancer in women
Women who get self breast exams, annual screenings with tomosynthesis provide early diagnosis
Once diagnosed, women are faced with treatment options that include:
Surgery
Radiation Therapy
Chemotherapy
Early detection offers an optimistic prognosis of 90% survival of those diagnosed
